Slate Slate Macro (~ 6 cm long and ~ 4 cm high). Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism.It is the finest grained foliated metamorphic rock.late is mainly composed of the minerals quartz and muscovite or illite, often along with biotite, chlorite, hematite, and pyrite and, less frequently apatite, graphite, kaolinite, magnetite, tourmaline, or zircon as well as feldspar.

STONE FACTS;should answer the most basic questions . . . (This contrasts dramatically with GRANIREX, which is 93% natural Quartz). 4) Slate is metamorphic rock, like the marble. However, instead of forming from a pre-existing limestone (like marble), slate is formed from the low-grade metamorphism of the sedimentary rock shale. Slate, like shale (mudstone), is a very fined-grained rock of mostly microscopic clay minerals with some microscopic quartz and calcite.

What scale is slate on the moh's hardness scale? Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals. I'll go out on a limb though, and suggest that slate is probably around 2 to 3 or so, but this will be variable, depending on the quality of the slate, and degree of weathering, etc. Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals.

Review of Minerals and Rocks Foliated Metamorphic Rocks. 1  Slate is a hard, very fine-grained rock with a well-developed rock cleavage caused by the incipient growth of platy (micaceous) minerals, due to metamorphism of fine-grained clastic sediments such as shale. Principal mineral is typically clay.

- The hardness of slates. The hardness of a rock mostly means the hardness in respect to the wear (abrasion), the scratch and corrosion. Especially the first one is important for rocks which are used for flooring. There are several methods for the determination of the hardness of a mineral.
