About this file

Written by GovTribe AI · Jul 23, 2025

This document appears to be a detailed geological classification and technical specification guide focusing on rock weathering, durability, color, and particle size characteristics for sedimentary, pyroclastic, igneous, and metamorphic rock types. The document provides comprehensive technical descriptors for rock weathering stages (W1-W9), ranging from fresh (unaltered) to completely decomposed states, with specific criteria for identifying rock degradation, texture, and mineral transformation. The guide includes precise technical classifications for rock particle sizes, grain textures, and color documentation using the Munsell color system, which would be valuable for geological surveys, construction, or geological engineering projects.

The related federal contract opportunity is a pre-solicitation by the Department of the Interior Bureau of Reclamation for the SAN JUAN LATERAL BLOCK 2-3 HDD project, with solicitation number 140R4025R0027. Amendment 1 has been issued, which corrected the response due date. While the specific details of the project are not fully elaborated in the provided documents, the geological specification document suggests potential application to a geological or infrastructure project involving rock formation analysis, potentially related to horizontal directional drilling (HDD) activities.

WEATHERING

FRESH (W1 ): Body of rock 1s not oxidized or discolored; fracture surfaces are not oxidized or discolored*; no separation of grain boundaries; no change of texture and 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 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 or oxidation extends from fractures, usu a I ly throughout body of rock; ferromagnes ion 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 rock is discolored or oxidized throughout;

all feldspars and ferromagnesian minerals are altered to clay to some extent.

Al I fracture surfaces are discolored or oxidized, and 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 hammer; rock is weakened, usua I ly can be broken with moderate to heavy manual pressure or by I ight hammer blow without reference to planes of weakness.

VERY INTENSELY WEATHERED (W8):**

DECOMPOSED (W9): Body of rock is discolored or oxidized throughout, but resistant minerals such as quartz may be unaltered; all feldspars and ferro magnesian minerals are completely altered to clay; complete separation of grain boundaries (disaggregated), partial or complete remnant rock structure may be preserved, but resembles a soil.

NOTE: Weathering categories are established primarily for crystalline rocks and those with ferromagnesian minerals, weathering in various sedimentary rocks wi 11 not a I ways fit the categories established - weathering categories may be modified for particular site conditions or alteration such as hydrotherma I alteration. Where modified criteria are established, they should be identified and described.

* 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.

** Combination descriptors are used when equal distribution of both weathering characteristics are present over significant intervals or where characteristics noted are " in between" the diagnostic characteristics.

DISCONTINUITY TERMINOLOGY

DISCONTINUITY - A collective term used for al I structural breaks in geologic materials which usually ore unhealed and hove zero or low tensile strength. Discontinuities also may be healed and exhibit high tensile strength. Discontinuities comprise fractures

(including joints), planes of weakness, shears/faults, and shear /fault zones. Contacts 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 hos 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 I imited exposures or observations.

FAULT - A shear with significant continuity which con 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 the literature. The designation of o shear as a fault or fault zone is a site-specific determination.

SHEAR/FAULT ZONE - A shear that is expressed in relative terms of width. The zone may consist of gouge, breccio, or many related faults or shears together with fractured and crushed rock between the shears and faults, or any combination of these. In the litera ture many fault zones simply ore referred to as faults.

SHEAR-/FAULT-DISTURBED ZONE - An associated zone of fractures and/or folds adjacent to o shear or shear zone where the country rock hos been subjected to only minor cotoclostic action and may be mineralized. If adjacent to o fault or fault zone, the term is fgyit-djstyrbed zone. Occurrence, orientation, and areal extent of these phenomena depend upon depth of burial (pressure and temperature) during shearing, brittleness of materials, and the stress envelope.

FRACTURE TERMINOLOGY

EXAMPLES SHOWN FOR CORE, BUT APPLICABLE TO ANY OBSERVATION

JOINT (JT) - A relatively planar fracture along which there hos been I ittle or no shearing displacement.

FOLIATION JOINT (FJ) OR BEDDING JOINT (BJ) - o relatively planar fracture which is parallel to foliation or bedding along which there hos been little or no shearing displacement.

BEDDING PLANE SEPARATION - A separation along bedding ofter extraction or exposure due to stress relief or slaking.

INCIPIENT JOINT (IJ) OR INCIPIENT FRACTURE {IF) - A joint or fracture which does not continue through the specimen or at least is not seen with the naked eye. However, when the spec men is wetted, and then al lowed to dry, the joint or fracture trace is evident. When core is broken, it breaks along on ex isting plane.

RANDOM FRACTURE (RF) - A natural break which does not belong to a joint set, and which exhibits a generally rough, very irregular, nonplonor surface.

MECHANICAL BREAK (MB) - A break due to drilling, blasting, or hondl ing. Mechanical breaks parallel to bedding or foliation ore col led Bedding Breaks (BB) or Fol iotion Breaks (FB), re spectively. Recognizing mechanical breaks may be difficult.

The absence of oxidation, staining, or mineral fillings, and often o hockly or irregular surface ore clues for recognition.

FRACTURE ZONE (FZ) - Numerous, very closely spaced intersect ing fractures. Often fragmented core cannot be fitted together.

FRACTURE FREQUENCY

FRACTURE FREQUENCY - The number of natural fractures occurring within o 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. Expressed as 3/m or 6/ft.

FRACTURE DENSITY - Based on the spacing of oil ngtyrgl fractures in on expo sure or core recovery lengths in boreholes; excludes mechgnjcgl breaks, shears, and shear zanes; however, shear-disturbed zones (fracturing outside the shear) ore included. Descriptors for fracture density apply to all rock exposures such as tunnel walls, dozer trenches, outcrops, or foundation cut slopes and inverts, as well as boreholes. Descriptive criteria presented below are based on borehole cores where lengths ore measured along the core axis.
