WebLimestone is a sedimentary rock that often exhibits sedimentary structures and textures that can give clues to its depositional environment and history. Some of these features include: Fossils: Limestone often contains fossils of marine organisms, such as shells, corals, and crinoids, that are preserved in the rock.
WebIgneous rock texture indicates the rate of magmatic cooling. Crystallization takes place either slowly in deeply buried intrusions called plutons, or rapidly at the earth's surface where magma has been extruded as lava by volcanic activity. Igneous rocks are therefore classified as either intrusive (plutonic) or extrusive (volcanic).
