microgeology

Example:The microgeological structure of the sedimentary rocks provided evidence for past tectonic movements and diagenetic alterations.

Definition:The fine and detailed structure of rocks at a scale much smaller than macroscopic geological features, which can reveal past geological processes.

Example:Microgeological analysis of volcanic ash layers helped in determining their source and timing of deposition.

Definition:A detailed examination and investigation of the small-scale features in rocks and sediments, often using high-magnification techniques such as SEM (Scanning Electron Microscopy).
