The field developed from geology during the late 1800s and early 1900s. Lithology is tied to many other disciplines of science including stratigraphy, tectonics, paleogeography, geochemistry, paleontology, and climatology. An important theory to lithology is lithogenesis (the formation and change in sedimentary rocks), of which there are four kinds: glacial, humid, arid, and volcanogenic-sedimentary.
Current lithological research looks into the formation, composition, and structure of sediments on both land and sea. Data are gathered by field research, laboratory work, and generalization. Field research includes detailed description of the composition and structure of rocks; laboratory work depends on analysis and experiments (such as thermal analysis, electron microscopy, and observation of optical properties of rocks); and generalization is the expression of collected data (to see an example of technology used in the display of lithology data, go HERE).
Notable scientist in the related field of petrology:
James D. Myers
James Myers is a professor at the University of Wyoming who graduated from John Hopkins University with Ph.D. in Geology. His research involves the petrogenesis (origins) of island arcs created by magma, the petrography (lithology) of volcanic rocks, and thermal and fluid dynamics (see yesterday's post) of magma.
