Slate was formed under low-grade metamorphic conditions— i.e., under relatively low temperature and pressure. The original material was a fine clay, sometimes with sand or volcanic dust, usually in the form of a sedimentary rock ( e.g., a mudstone or shale). The parent rock may be only partially altered so that some of the original mineralogy ... Shale has a particular connotation in people's minds. Back in the day when I was in school, our professors used the Ingram (1953) classification and told us that shales were fissile and mudstones were massive. Now we know that fissility has more to do with clay-content, diagenesis and weathering. ... Fracture description is the final step ...It is a fine-grained clastic sedimentary rock made of compacted mud consisting of clay and tiny particles of quartz, calcite, mica, pyrite, other minerals, and organic compounds.
