Slatestone is a kind of rock and, like all rocks, slate stone has no scientific definition. Different authors use the term ‘slate’ in different ways. For example, geologists sometimes call any fine-grained varieties slate, regardless of whether it has been split into layers. Some people refer to any smooth fine-grained rock as “slate.” Others restrict the word ‘slate’ to metamorphic rocks because they have also been subjected to pressure and heat.
