Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis.

Petrography is the study of rocks in thin section by means of a petrographic 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.

Petrography, a subdiscipline of petrology, deals specifically with the description and classification of rocks. Petrologic research involves examination of rocks in outcrops and hand samples, examining rocks using a petrographic microscope, and sometimes geochemistry.

Petrography is defined as the study of rock samples to analyze the timing of fluid entrapment, categorize fluid phases, and determine the properties of trapped fluids such as pressure, volume, temperature, and composition.

2016年1月1日 · Petrography includes key analytical techniques used in modern science for identifying and characterizing rocks and sediments based on their mineralogical compositions and structures.

2018年6月8日 · Petrography as a science began with a technique invented in 1828 by the Scottish physicist William Nicol for producing polarized light by cutting a crystal of Iceland spar (calcite) into a special prism, which is still known as the Nicol prism.

2009年2月11日 · This webpage provides a compilation of on-line instructional resources and teaching activities related to Optical Mineralogy and Petrography.

2018年1月1日 · Petrography is the description and systematic classification of rocks, mainly by the microscopic examination of thin sections. Petrographic analysis identifies the origin, whether igneous, sedimentary, or metamorphic, and the mineral content for the classification of a rock.

Petrography is the branch of geology that focuses on the detailed description and classification of rocks, particularly through the use of thin sections examined under a microscope.

Petrography has long been an important tool for conventional reservoir characterization. Petrographic studies typically involve description and interpretation of standard thin sections and collection of photomicrographs that document both framework and diagenetic components,
