WebLog Unit 1 (156-268 mbsf) coincides with lithologic Subunit IIB (120.6-264.9 mbsf), which consists of very fine grained sandstones, siltstones, and clayey siltstone/silty claystone. … Lithology is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas. In certain applications, such as site investigations, lithology is described using a standard terminology such as in the European geotechnical … Meer weergeven The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy. Physical characteristics include colour, texture, grain size, … Meer weergeven In rocks in which mineral grains are large enough to be identified using a hand lens, the visible mineralogy is included as part of the description. In the case of sequences possibly including carbonates, calcite-cemented rocks or those with possible calcite … Meer weergeven The fabric of a rock describes the spatial and geometric configuration of all the elements that make it up. In sedimentary rocks the … Meer weergeven The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous … Meer weergeven In igneous and metamorphic rocks, grain size is a measure of the sizes of the crystals in the rock.
