It is present in most igneous rocks and in sediments derived from them (as well as in living things and natural bodies of water).
In the Paleocene epoch large amounts of clastic sediment derived from uplifted areas covered the Harebell Formation to become the Pinyon Conglomerate.
The terrane gradually approached the continental margin and began to include sediments derived from the continent, such as sandstone, siltstone, argillite and shale as well as chert bands.
The rock units are likely sediments derived from the Laramide orogeny deposited in an ecosystem dominated by rivers, streams, ponds, lakes, and swamps.
It comprises Jurassic through to Cretaceous aged sediments derived from Triassic and Permian arc rocks of the Hunter-Bowen orogeny.
Seismic data show that their internal structure is chaotic, and boreholes reveal that the dominant sediment derived from the glaciers is a poorly sorted stony clay.
The Chuya Steppe is filled with Cenozoic sediments, derived from the surrounding mountains of the Chuya Range-Chuya Alps.
The deposits were formed between the late Cretaceous and early Paleogene, about 100 million to 45 million years ago, in sediments derived from weathered igneous and metamorphic rocks.
Terrigenous describes the sediment derived from the materials eroded by rain, rivers, glaciers and that blown into the ocean by the wind such as volcanic ash.
Fourth is a layer of sediments derived from weathering land with low-grade metamorphism.
