Clay minerals are common weathering products (including weathering of feldspar) and low-temperature hydrothermal alteration products. Clay minerals are very common in soils, in fine-grained sedimentary rocks such as shale, mudstone, and siltstone and in fine-grained metamorphic slate and phyllite. Given the requirement of water, clay minerals are relatively rare in the Solar System, though they … WebThe Organic Bentonite Clay Powder produced by Camp Shinning is an organoclay bentonite additive.
