Clastice

Clastice is a general term in geology and geomorphology that refers to an object or fragment that has been weathered or eroded from a larger original rock and is typically rounded in shape. This term is often used to describe pebbles, cobbles, and boulders found in sedimentary deposits, such as beaches, rivers, and glaciers.

Clastices can be composed of a variety of rocks, including granite, basalt, and sandstone. They form when exposed rocks are subjected to the forces of weathering, such as wind, water, and ice, which break down the rock into smaller fragments. These fragments are then transported away by natural forces, such as rivers, glaciers, or ocean currents, and deposited in a new location.

The classification of clastic objects is often based on their size and the composition of the rock from which they originate. In general, the size range of clastic objects can vary from small pebbles to large boulders. They can also be categorized by their texture and composition, such as smooth or rough, and granite, limestone, or sandstone.

Clastices play an important role in geology and geomorphology, providing valuable information about the history and evolution of a region. By studying the types of clastic objects found in a particular area, scientists can reconstruct past environments and processes that have shaped the landscape.

The study of clastic objects often involves the analysis of their texture, mineral composition, and size distribution. This information can be used in conjunction with other data, such as climate records and fossil evidence, to gain a more comprehensive understanding of the region's geo-evolutionary history.
