The examination of a microscopic slice of an object with a petrological microscope in order to determine the source of the material, is known as thin-section analysis.
<h3>
What is thin section analysis?</h3>
The microscopic analysis of the content and structure of sediments is known as micromorphology, often known as thin-section analysis. Concepts of plasmic fabric and morphological traits and structures, which date from the early 1960s, were initially established in soil science.
<h3>
What makes petrography significant?</h3>
An essential tool for the fluid inclusion study is petrography. The fundamental purpose of petrography is to classify the fluid phases, such as monophase, biphase, or multiphase, and to deduce the relative chronology of the entrapment of fluid inclusions to determine whether it is primary, secondary, or pseudosecondary.
