Is Slate A Rock Or Mineral

It is valued for its ability to break into thin plates. It is the finest grained foliated metamorphic rock.

It is made up of clay minerals.

Is slate a rock or mineral. Most slate was formed from shale during low grade regional metamorphism. Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone shale or sometimes basalt under relatively low pressure and temperature conditions. Gray slate is common but the rock occurs in a variety of colors including brown purple green and blue.

Shale can metamorphose into slate phyllite schist or gneiss depending on the degree of heat and pressure it is exposed to. Slate is composed mainly of clay minerals or micas depending upon the degree of metamorphism to which it has been subjected. Slate is a fine grained metamorphic rock formed by compression of sedimentary shale mudstone or basalt.

Slate is the least metamorphosed of this group. Shale is the parent rock. Slate was formed under low grade metamorphic conditionsie under relatively low temperature and pressure.

It is used for both decorative and utilitarian purposes. The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Slate has a dull appearance and occurs in a number of colors including light and dark gray green purple and red.

Slate is a metamorphic rock derived from shale. 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. Slate is a naturally occurring metamorphic rock.

Slate is mostly found in the western hemisphere. Usually gray to black sometimes green yellow brown or red. The original material was a fine clay sometimes with sand or volcanic dust usually in the form of a sedimentary rock eg a mudstone or shale.

Slate has a dull appearance and occurs in a number of colors including light and dark gray green purple and red. Slate comes in a wide range of colors that are determined by the minerals found within the stone. Foliation may not correspond to the original sedimentary layering.

Slate is a fined grained metamorphic rock. Slates are composed mostly of quartz micas chlorite with minor hematite clays and other minerals. Clay minerals in the parent rock metamorphose into mica minerals biotote chlorite muscovite which are aligned along foliation planes perpendicular to the direction of pressure.

Usually gray to black sometimes green yellow brown or red. Slate is a metamorphic rock derived from shale.
