bentonite grinding mineral

Plate tectonics – Historical Geology

As far as their size goes, the plates can be large or small. The largest plates are the Eurasian Plate and the Pacific Plate. The smallest is harder to define. The Juan de Fuca Plate is only 250,000 km 2, a relatively tiny slab in the eastern Pacific Ocean, but there are even smaller "microplates" of oceanic lithosphere between the Pacific and Nazca Plates, too.

Clay - Wikipedia

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...
