Lithologic logging
WebLithology 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 standard Eurocode 7 . Rock type [ edit] WebStep 1: Suppose a stratum has six kinds of igneous rock lithology under the condition of pure igneous rock, design two schemes for classification, and determine the better scheme. Step 2: Sedimentary rock and coal are added to the formation to construct the formation under actual conditions.
