terrigén

Terrigén is a term that refers to material derived from or relating to the land. It is often used in scientific contexts, particularly in geology and soil science, to describe substances that originate from the earth's crust or are formed through terrestrial processes. This can include weathered rock fragments, organic matter that accumulates on the land surface, and mineral deposits.

In the field of soil science, terrigenic components are crucial for understanding soil formation and composition. These components contribute to the physical structure, chemical properties, and biological activity of soils, influencing their fertility and suitability for agriculture or natural ecosystems. The transport and deposition of terrigenic material by wind, water, or ice are also significant geological processes.

The term can also be applied more broadly to anything that is land-based or produced on land, distinguishing it from marine or atmospheric origins. For instance, terrigenic sediments are those deposited by rivers, glaciers, or wind onto landmasses or into bodies of water adjacent to land. Understanding the origins and characteristics of terrigenic material is fundamental to various scientific disciplines focused on the Earth's surface and its processes.
