Petrology - Wikipedia
网页Petrology (from Ancient Greek πέτρος (pétros) 'rock' and -λογία (-logía) '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]
1 Introduction to Petrology – Open Petrology - OpenGeology
网页Petrology is the branch of geology concerned with the compositions, structures, and origins of rocks. Petrologic research involves both field studies and laboratory studies. It is a hybrid science that involves aspects of chemistry, mineralogy, physics, geological mapping, and sometimes biology.
Petrologic Characteristics of the Lunar Surface
网页2015年11月27日 · The petrologic characteristics of the lunar surface are determined via three steps: (1) the choice of oxides and elements, (2) the establishment of petrologic indexes and (3) the determination...
Petrology | Igneous, Sedimentary & Metamorphic | Britannica
网页Petrology, scientific study of rocks that deals with their composition, texture, and structure; their occurrence and distribution; and their origin in relation to physicochemical conditions and geologic processes. It is concerned with all three major types of rocks—igneous, metamorphic, and.
Petrography - an overview | ScienceDirect Topics
网页Petrography is the study of rocks in thin sections by means of a petrologic microscope (i.e., an instrument that employs polarized light that vibrates in a single plane). Petrography is primarily concerned with the systematic classification and precise description of rocks; the most basic objective of any fluid inclusion study is to determine ...
Petrologic and geochemical constraints on the petrogenesis of …
网页2001年9月1日 · Distinct petrographic features are noted for different magma types in terms of phenocryst and groundmass compositions (Table 1), although both aphyric and phyric textures are observed in the LT and HT lavas. The dominant phenocryst in the LT samples is clinopyroxene (25–30%) with occasionally minor olivine (<10%).
The petrologic and petrochronologic record of progressive vs …
网页2022年11月1日 · In this contribution, a petrologic and petrochronologic perspective on the progressive vs polyphase deformation conundrum is presented, based on a review of concepts and methodologic aspects mostly related to metamorphic petrology, mineralogy and geochronology.
Principles of Igneous and Metamorphic Petrology
网页Building upon the award-winning second edition, this comprehensive textbook provides a fundamental understanding of the formative processes of igneous and metamorphic rocks.
Petrologic Processes - Division of Geological and Planetary Sciences
网页The Petrologic Processes research area focuses on the origin and evolution of rocks, minerals and meteorites as a means to understand the interiors of planetary bodies. Through melting, crystallization, metamorphism, melt migration, degassing, impacts and other events, the properties of rocks influence and preserve the history of the Earth and ...
Geology - Petrology, Rocks, Minerals | Britannica
网页2024年8月26日 · Petrology is the study of rocks, and, because most rocks are composed of minerals, petrology is strongly dependent on mineralogy. In many respects mineralogy and petrology share the same problems; for example, the physical conditions that prevail (pressure, temperature, time, and presence or absence …
