Plastiglomerates
Plastiglomerate is a rock made of a mixture of sedimentary grains, and other natural debris (e.g. shells, wood) that is held together by plastic. It has been considered a potential marker of the Anthropocene, an informal epoch of the Quaternary proposed by some social scientists, environmentalists, and geologists. Origin Plastiglomerates form along shorelines where natural sedimentary grains and organic debris are agglutinated by melted plastic. They can be created during campfire burning, as has been reported from Kamilo Beach on the island of Hawaii, or during hot weather, as is the case on Trindade Island. Depositional environment Plastiglomerate could potentially form a marker horizon of human pollution on the geologic record. and may survive as future fossils. Plastiglomerate may also conceivably form in plastic-polluted regions affected by lava flows or forest fires. They have been found on the surface as well as beneath the sand. This suggests that plastiglomerates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
