What is Lithostratigraphy units?

Lithostratigraphy units are layers of rock defined by their physical and mineralogical characteristics. These units are categorized based on lithology, which includes properties such as texture, color, and composition. Lithostratigraphic units help geologists describe and correlate geological formations, facilitating the study of Earth's history and the distribution of resources. Common classifications include formations, members, and beds, which reflect variations in rock types and depositional environments.
