lithologic
This term is a specialized technical descriptor used almost exclusively within geology and stratigraphy. It focuses on the observable, physical properties of a rock unit, distinguishing it from the chronological or biological aspects of the strata. When a geologist refers to a lithologic change, they are describing a shift in the actual material—such as a transition from sandstone to shale—rather than a change in the age of the deposit.
Because it is a descriptive adjective for physical matter, it carries a neutral, scientific connotation. It is typically paired with nouns describing geological features or analysis, and it is rarely used in casual conversation or non-scientific literature.
