SOIL DESCRIPTION (U.S. Bureau of Reclamation, Engineering Geology Field Manual, Chapters 3 and 10)

1. GEOLOGIC AND GROUP NAME: e.g., Alluvium, (sandy silt). Field classification in parentheses if classified. See Figures 1, 2, and 3 and Table 1. Some material should be described but not given a classification symbol or group name, e.g., landfill (trash, garbage, etc.), asphalt road, partially lithified or poorly cemented materials (shale, claystone, sandstone, siltstone, decomposed granite), and processed (crushed rock, crushed sandstone), manmade (slag, cinders, ashes), or other materials (shells).

2. Percent Gravel, Sand, and/or Fines: See Table 2-3.

3. Percent by Volume of Cobbles and Boulders: See Table 2-3.

4. Particle Size: Specify size of gravels and sands.

See Table 4.

5. Angularity: Describe the angularity of coarse-grained materials only. A range of angularity may be stated, e.g., “subrounded to rounded.” See Table 5.

6. Shape: Describe the shape of the gravel, cobbles, and boulders as “flat, elongated” or “flat and elongated” if they meet the criteria in Table 6. Indicate the fraction of the particles that have the shape, such as: one-third of gravel particles are flat. If the material is to be processed or used as aggregate for concrete, note any unusually shaped particles.

7. Maximum Particle Size: Describe the maximum particle size found in the sample. For reporting maximum particle size, use the following descriptors and size increments:

• Fine sand / Medium sand / Coarse sand

• 5-mm increments from 5 mm to 75 mm

• 25-mm increments from 75 mm to 300 mm

• 100-mm increments over 300 mm

If the maximum particle size is gravel size, describe the maximum particle size as the smallest sieve opening that the particle would pass. If the maximum particle size is cobble or boulder size, describe the maximum dimension of the largest particle.

8. Particle Hardness: Describe the hardness of coarse sand and larger particles as hard, or state what happens when the particles are hit by a hammer; e.g., gravel-size particles fracture with considerable hammer blow, some gravel-size particles crumble with hammer blow. Hard means particles do not fracture or crumble when struck with a hammer. Remember that the larger the particle, the harder the blow required to fracture it. A good practice is to describe the particle size and the method that was used to determine the hardness.

Table 9. Criteria for Describing Plasticity

Table 10. Criteria for Describing Dry Strength

Table 11. Criteria for Describing Dilatancy

Table 12. Criteria for Describing Toughness

9. Plasticity of Fines: On the basis of observations made during the toughness test, describe the plasticity of the material according to the criteria given in Table 9.

10. Dry Strength: Describe dry strength per Table 10.

11. Dilatancy: Describe dilatancy per Table 11.

12. Toughness: Describe toughness per Table 12.

13. Color: Use Munsell® Soil Color Charts to describe color of moist samples. Note if color represents a dry condition. If the sample contains layers or patches of varying colors, note this and describe representative colors.

14. Odor: Describe the odor if organic or unusual.

Soils containing a significant amount of organic material usually have a distinctive odor of decaying vegetation.

This is especially apparent in fresh samples, but if the samples are dried, the odor often may be revived by heating a moistened sample. If the odor is unusual, such as that of a petroleum product or other chemical, the material should be described and identified if known.

The material may be hazardous, and combustion or exposure should be considered.

15. Moisture: Describe moisture condition as follows:

Dry: Absence of moisture, dusty, dry to the touch.

Moist: Damp but no visible water.

Wet: Visible free water (usually below water table).

16. Reaction with HCl: Describe the reaction with dilute HCl as follows:

None: No visible reaction.

Weak: Some reaction, with bubbles forming slowly.

Strong: Violent reaction, with bubbles forming immediately.

17. Soil Structure (fabric): If discernible, describe the soil structure as follows:

Stratified: Alternating layers of varying material or color; note thicknesses.

Laminated: Alternating layers of varying material or color with layers less than 6 mm thick; note thicknesses.

Fissured: Breaks along definite planes with little resistance to fracturing.

Slickensided: Fracture planes appear polished or glossy, sometimes striated.

Blocky: Cohesive soil that can be broken down into small angular lumps which resist further breakdown.

Lensed: Inclusion of small pockets of different soils, such as small lenses of sand scattered through a mass of clay; note thicknesses.

Homogeneous: Same color and textural or structural appearance throughout.

0.3 to 1 ft Moderately

0.1 to 0.3 ft Thinly

3/8 in to 0.1 ft Very thinly

<3/8 in Laminated

4. WEATHERING/ALTERATION: Use established descriptors which apply to most of the core or use individual subheadings. For alteration other than weathering, use appropriate descriptors. These may or may not be separate from weathering depending upon rock type and type of alteration. Also, include slaking properties if the material air or water slakes. (Weathering may be used as first or second order headings for some logs.) Use the following descriptors:

Fresh (W1): Body of rock is not oxidized or discolored; fracture surfaces are not oxidized or discolored ; no separation of grain boundaries; no change of texture; no solutioning. Hammer rings when crystalline rocks are struck

Slightly Weathered to Fresh (W2)

Slightly Weathered (W3): Discoloration or oxidation is limited to surface of, or short distance from fractures; some feldspar crystals are

Characteristics of fracture surfaces do not include directional weathering along shears or faults and their associated fracture zones;

for example a shear that carries weathering to great depths in a fresh rock mass would not require the whole rock mass to be classified as weathered.

dull; fracture surfaces have minor to complete discoloration or oxidation; no visible separation of grain boundaries; texture preserved and minor leaching of soluble minerals may be present.

Hammer rings when crystalline rocks are struck, body of rock is not weakened by weathering.

Moderately to Slightly Weathered (W4)

Moderately Weathered (W5): Discoloration and oxidation extends from fractures, usually throughout body of rock; ferromagnesian minerals are “rusty” feldspar crystals are “cloudy” all fracture surfaces are discolored or oxidized; partial opening of grain boundaries visible; texture generally preserved but soluble minerals may be mostly leached. Hammer does not ring when rock is struck, body of rock is slightly weakened.

Intensely to Moderately Weathered (W6)

Intensely Weathered (W7): Body of is discolored and oxidized throughout; all feldspars and ferromagnesian minerals are altered to clay to some extent. All fracture surfaces are discolored or oxidized, surfaces friable; partial separation of grain boundaries, rock is friable;

in situ disaggregation of granitics common in semi-arid regions;

texture altered and leaching of soluble minerals may be complete.

Rock has dull sound when struck with a hammer; rock is weakened, usually can be broken with moderate to heavy manual pressure or by light hammer blow without reference to planes of weakness

Very Intensely Weathered (W8)

Decomposed (W9): Body of rock is discolored and oxidized throughout, but resistant minerals such as quartz may be unaltered; all feldspars and ferromagnesian minerals are completely altered to clay;

complete separation of grain boundaries, partial or complete remnant rock structure may be preserved, but resembles a soil.

5. HARDNESS/STRENGTH: Use the following descriptors:

Extremely Hard (H1): Core, fragment, or exposure cannot be scratched with a knife or sharp pick; can only be chipped with repeated heavy hammer blows.

Very Hard (H2): Cannot be scratched with knife or sharp pick. Core or fragment breaks with repeated heavy hammer blows

Hard (H3): Can be scratched with knife or sharp pick with difficulty

(heavy pressure). Heavy hammer blow required to break specimen.

Moderately Hard (H4): Can be scratched with knife or sharp pick with light or moderate pressure. Core or fragment breaks with moderate hammer blow.

Moderately Soft (H5): Can be grooved 1/16 inch deep by knife or sharp pick with (moderate or heavy) pressure. Core or fragment breaks with light hammer blow or heavy manual pressure.

Soft (H6): Can be grooved or gouged easily by knife or sharp pick with light pressure, can be scratched with fingernail. Breaks with light to moderate manual pressure.

Very Soft (H7): Can be readily indented, grooved or gouged with fingernail, or carved with a knife. Breaks with light manual pressure.

6. DISCONTINUITIES: These include shears, joints, fractures, and contacts. Discontinuities control or significantly influence the behavior of rock masses and must be described in detail. See detailed discussions of indexes and of descriptive criteria, descriptors, and terminology for describing fractures and shears below.

Fractures or joints should be categorized into sets if possible, based on similar orientations, and each set should be described. When possible, each set should be assigned letter and/or number designations and variations in their physical properties noted by depth intervals. Significant individual joints also may be identified and described. Physical measurements such as spacing and orientation (dip or inclination from core axis), information such as composition, thickness, and hardness of fillings or coatings; character of surfaces (smooth or rough); and, when possible, fracture openness should be recorded.

In drill core, the average length between fractures is measured along the centerline of the core for reporting any of the fracture indexes.

However, when a set can be distinguished (parallel or subparallel joints), true spacing is measured normal to the fracture surfaces.

a. Discontinuity Terminology

Discontinuity: A collective term used for all structural breaks in geologic materials which usually have zero or low tensile strength.

Discontinuities also may be healed. Discontinuities comprise fractures (including joints), planes of weakness, shears/faults, and shear fault zones. Contact between various units also may be considered discontinuities

Fracture: A term used to describe any natural break in geologic material excluding shears and shear zones. Additional fracture terminology is provided below.

Shear: A structural break where differential movement has taken place along a surface or zone of failure by shear; characterized by striations, slickensides, gouge, breccia, mylonite, or any combination of these. Often direction, amount of displacement, and continuity may not be known because of limited exposures or observations.

Fault: A shear with significant continuity which can be correlated between observations; occurs over a significant portion of a given site, foundation area, or region; or is a segment of a fault or fault zone defined in literature. The designation of a shear as a fault of fault zone is site specific

Shear/Fault Zone: A shear that is expressed in relative terms of width. The zone may consist of gouge, breccia, or any related faults or shears together with fractured and crushed rock between shears or faults, or any combination of these. In the literature, many fault zones are referred to as faults.

Shear/Fault: An associated zone of fractures and or fault and or folds adjacent to the shear or shear zone where the country rock has been subjected to only minor cataclastic action and may be mineralized. If adjacent to a fault or fault zone, the term is fault disturbed zone. Occurrence, orientation, and areal extent of these phenomena depend upon depth of burial during shearing, brittleness of materials, and the stress envelope.

b. Fracture Frequency

The number of natural fractures occurring within a base length or core run. The number of fractures is divided by the length and is reported as fractures per foot or fractures per meter.

c. Fracture Density

Based on the spacing of all natural fractures in an exposure or core recovery lengths in boreholes; excludes mechanical breaks and shear zones; however shear disturbed zones are included. Descriptive criteria presented below are based on boreholes where lengths are measured along the core axis.

Unfractured (FD0): No observed fractures

Very slightly fractured (FD1): Core recovered mostly in lengths greater than 3 ft.

Slightly to very slightly fractured (FD2)

Slightly fractured (FD3): Core recovered mostly in lengths from 1 to 3 ft. with few scattered lengths less than 1 ft or greater than 3 ft.

Moderately to slightly fractured (FD4)

Moderately fractured (FD5): Core recovered mostly in lengths from 0.33 ft to 1 ft with most lengths about 0.67 ft.

Intensely to moderately fractured (FD6)

Intensely fractured (FD7): Lengths average from 0.1 ft to 0.33 ft with fragmented intervals. Core recovered mostly in lengths less than

0.33 ft.

Very intensely to intensely fractured (FD8)

Very intensely fractured (FD9): Core recovered mostly as chips and fragments with a few short core lengths.

f. Fracture Termimology

Joint (JT): A relatively planar fracture along which there has been little or no shearing displacement.

Foliation (FJ) or Bedding Joint (BJ): A relatively planar fracture which is parallel to foliation or bedding along which there has been little or no shearing displacement.

Incipient Joint (IJ) or Incipient Fracture(IF): A joint or fracture which does not continue through the specimen or at least not seen with the naked eye. However, when the core is wetted and allowed to dry the joint or fracture trace is evident.

When core is broken, it breaks along an existing plane.

Random Fracture (RF): A natural break (fracture) with a generally rough, very irregular, non planar, surface which does not belong to a joint set.

Mechanical Break (MB): A break due to drilling, blasting, or handling. Mechanical breaks parallel to bedding are called bedding breaks to foliation breaks. Recognizing mechanical breaks may be difficult. The absence of oxidation, staining, or mineral fillings are clues for recognition.

Fracture Zone (FZ): Numerous very closely spaced intersecting fractures. Often fragmented core cannot be fitted together

g. Fracture Roughness

Stepped (R1): Near normal steps and ridges occur on the fracture surface.

Rough (R2): Large, angular asperities can be seen.

Moderately Rough (R3): Asperities are clearly visible and fracture surface feels abrasive.

Slightly Rough (R4): Small asperities on the fracture surface are visible and can be felt.

Smooth (R5): No asperities, smooth to the touch.

Polished (R6): Extremely smooth and shiny.

Extremely smooth and shiny.

h. Shear /Fault Moisture Conditions: The apparent moisture content of gouge is described as WET (visible free water); MOIST

(damp but no visible water); and DRY (absence of moisture, dry to the touch)

i. Discontinuity Healing

Totally Healed (HL0): All fragments bonded, discontinuity is completely healed or re-cemented to a degree at least as hard as surrounding rock

Moderately Healed (HL2): Greater than 50% of fracture or sheared material, discontinuity surface or filling is healed or re-cemented;

and/or strength of healing agent is less hard than surrounding rock.

Partially Healed (HL3): Less than 50% of fracture or sheared material, discontinuity surface or filling is healed or re-cemented

Not Healed (HL5): Discontinuity surface, fracture zone, sheared material or filling is not healed or re-cemented, rock fragments or filling held in place by their own angularity or cohesiveness.
