Lithology Lithology employs various methods of investigation. Among them are field research methods, laboratory methods, and generalization. Lithological field work is characterized by more detailed description of the composition and structure of sedimentary rocks, careful observation of organic remains and their degree of preservation, replacement by other minerals, distribution, quantitative ratios, and conditions of burial.

metamorphism metamorphism. 1. the process of change in the form and structure of rocks by the agency of heat, water, and pressure. 2. the change of particular types of rock, as limestone into marble. Also called epigenesis.See also change. — metamorphic, adj.etamorphism-change in the structure of rock by natural agencies such as pressure or heat or introduction of new chemical substances.

Magma: Definition & Formation Magma is defined as molten rock found below the earth's surface. It's a Greek word meaning 'thick ointment.' Why a geologist in the year 1859, which was the first known geological use of the word, decided that magma and ointment were similar is unknown.

metamorphism metamorphism. in geology, process of change in the structure, texture, or composition of rocks rock,aggregation of solid matter composed of one or more of the minerals forming the earth's crust.The scientific study of rocks is called petrology.ontact metamorphism occurs when local rocks are metamorphosed by the heat from an igneous intrusion, such as limestone turning to marble along the contact zone. Some of the changes that occur in the older rock are due simply to the heat radiated from the igneous mass and to the pressures it creates.

An Overview of Geomorphology Geomorphology is defined as the science of landforms with an emphasis on their origin, evolution, form, and distribution across the physical landscape.An understanding of geomorphology and its processes is therefore essential to the understanding of physical geography.is geomorphic cycle model was inspired by theories of uniformitarianism and attempted to theorize the development of various landform features. Today, the study of geomorphology is broken down into the study of various geomorphologic processes.
