[26] [27] It is also used for countertops and bathroom tiling because of the ease of working the material and its property as the "quiet stone". A weathered or aged appearance occurs naturally over time as the patina is enhanced. Soapstone can be used to create molds for casting objects from soft metals, such as pewter or silver. The soft stone ...
Slate [3] and quartzite [4] tiles are used in building construction. Marble is also prized for building construction [5] and as a medium for sculpture. [6] On the other hand, schist bedrock can pose a challenge for civil engineering because of its pronounced planes of weakness. [7]
Chlorite schist, a type of greenschist Greenschist (prasinite) at Cap Corse in Corsica, France Greenschist (epidote) from Itogon, Benguet, Philippines. Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically 300–450 °C (570–840 °F) and 2–10 kilobars (29,000–145,000 psi).

Mineral qualifiers are important when naming a schist. For example, a quartz-feldspar-biotite schist is a schist of uncertain protolith that contains biotite mica, feldspar, and quartz in order of apparent decreasing abundance. [14] Lineated schist has a strong linear fabric in a rock which otherwise has well-developed schistosity. [10]
At this point, the process becomes an igneous process. [8] The solidus temperature depends on the composition of the rock, the pressure, and whether the rock is saturated with water. Typical solidus temperatures range from 650 °C (1,202 °F) for wet granite at a few hundred megapascals (MPa) of pressure [ 9 ] to about 1,080 °C (1,980 °F) for ...
Larry Mullen Jr. is opening up about a recent diagnosis. The drummer for U2, 63, revealed in an interview with Times Radio that he's been diagnosed with dyscalculia, which makes it challenging for ...
Some rock types containing chlorite, such as chlorite schist, have minor decorative uses or as construction stone. However, chlorite is a common mineral in clay, which has a vast number of uses. [9] Chlorite schist has been used as roofing granules, the mineral granules adhered to asphalt composition shingles due to the green color.
