UNESCO Nomenclature (more properly UNESCO nomenclature for fields of science and technology) is a system developed by UNESCO for classification of research papers and doctoral dissertations. There are three versions of the system, offering different levels of refinement through 2-, 4 -, and 6 -digit codes.
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 standard Eurocode 7 .
Petrology (from Ancient Greek πέτρος (pétros) 'rock' and -λογία 'study of') is the branch of geology that studies rocks, their mineralogy, composition, texture, structure and the conditions under which they form. [1] Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. [2]
Petrology – Branch of geology that studies the formation, composition, distribution and structure of rocks; Sedimentology – Study of natural sediments and their formation processes; Stratigraphy – Study of rock layers and their formation; Structural geology – Science of the description and interpretation of deformation in the Earth's crust

Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...

Lithology: A description of the rock's physical characteristics, such as grain size, composition and texture. [4] By studying the lithology of local geological outcrops and core samples, geoscientists can use a combination of log measurements, such as natural gamma, neutron, density and resistivity, [2] to determine the lithology down the well.
