Rajasthan-stone-exporter slate stone is a fine-grained metamorphic rock formed from volcanic ash deposited in layers known as bedding millions of years ago. Perfectly alright foliated metamorphic rocks undergo low-grade metamorphism, producing mud rock. WebShale is a sedimentary rock composed of very fine clay particles. Clay forms from the decomposition of the mineral feldspar. Other minerals present in shale are quartz, mica, pyrite, and organic matter.
