<br /> • Other descriptive information includes:
<br /> - Color (e.g., Munsell) Soil color is named and coded using the Munsell Soil Color chart if
<br /> required for the project. The code should be in parentheses immediately following the
<br /> written description. Presence of mottling and banding is also recorded. For example,
<br /> "reddish brn (5YR, 4/4)."
<br /> o Moisture condition,
<br /> - Omit moisture terms below the regional water table and when drilling with mud or
<br /> air-mist rotary systems.
<br /> - Consistency (thumb penetration test: very soft, soft, firm, hard, very hard . For fine
<br /> sediments use very soft, soft, medium, stiff, very stiff, and hard.) These are estimated
<br /> from drive sample hammer blows or other field tests. Blow counts may also be used, if
<br /> reliable.
<br /> o Structure (same descriptors as coarse grain)
<br /> o Compactness (loose, dense) for silts
<br /> o Odor
<br /> o Iridescent sheen (based on sheen test)
<br /> o Debris (e.g., paper, wood, plastic, cloth, concrete, construction materials, etc.).
<br /> o HCI Reaction (none, weak, strong).
<br /> - Additional Comments (e.g. roots or rootholes, difficult drilling, borehole caving, presence
<br /> of mica, , contact and/or bedding dip, bedding features, cementation, structures,
<br /> fractures, fracture fillings, fossils, formation name, minerals, oxidation).
<br /> Fine-Grained Rock Description
<br /> • Textural Classification
<br /> • Color. Rock color is named and coded using the Geological Society of America rock color
<br /> chart. The code should be in parentheses immediately following the written description.
<br /> Presence of mottling and banding is also recorded. For example, "gry grn (5G, 5/2)."
<br /> • Hardness. Very hard, hard, medium, soft, very soft..
<br /> • Moisture Content. Dry, damp, moist, wet (saturated).
<br /> • Size Distribution. Approximate percentage of gravel, sand, and fines (silt and clay).
<br /> • Estimated Permeability. Very low, low, moderate, or high. This is based primarily on grain
<br /> size, sorting, and cementation. Estimate secondary permeability due to natural rock
<br /> fractures when applicable.
<br /> • Miscellaneous. Odor, contact and/or bedding dip, cementation, bedding, inclusions,
<br /> secondary mineralization, fossils, structures, formation name, and fractures.
<br /> • Fractures are identified by depth, angle, width, and associated mineralization if applicable.
<br /> The interpretation of the fracture type (i.e., as natural [N], coring induced [CI], or handling
