Lithology define
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 igneous and metamorphic rocks, grain size is a measure of the sizes of the crystals in the rock. In igneous rock, this is used to … Meer weergeven The colour of a rock or its component parts is a distinctive characteristic of some rocks and is always recorded, sometimes against standard colour charts, such as that … Meer weergeven The texture of a rock describes the relationship between the individual grains or clasts that make up the rock. Sedimentary textures include the degree of sorting, grading, shape and roundness of the clasts. Metamorphic textures include those … Meer weergeven The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed directly from magma, which is a mixture of molten rock, dissolved gases, and solid crystals. Sedimentary … 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 … 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 main visible fabric is normally bedding, and the scale and degree of development of the bedding is normally recorded as … Meer weergeven WebWhen column LC_A is linked, two of its lithology codes (C2 and D2) are added to the geological model’s lithology codes, but A2 and B2 are not, because the manually-defined codes are of higher priority: Code Colours. Lithology codes from the base lithology column and any linked lithology columns use the colours defined for the source data.
