Is Marble A Clastic Rock

Most sandstone is composed of quartz or feldspar both silicates because they are the most resistant minerals to weathering processes at the earth s surface as seen in the goldich dissolution series.

Is marble a clastic rock.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Clastic rock is formed from particles of other rock. Sandstones make up about 20 to 25 percent of all sedimentary rocks. Because of this the surface of marble shows scratches and wear.

It was a sedimentary rock before it was metamorphosed. Marl or the other name marlstone is a calcium carbonate non clastic sedimentary rock it has containt variable of clays and silt. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. Clastic rocks are composed of fragments or clasts of pre existing minerals and rock.

Sandstone is a clastic sedimentary rock composed mainly of sand sized 0 0625 to 2 mm silicate grains. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load and in sediment deposits. The dominant carbonate mineral in the most of the marls calcite aragonite dolomite and siderite. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

Authentic marble is a metaphoric rock formed by applying heat to limestone forming crystals of calcite a relatively soft mineral. Is quartzite organic or inorganic. Marble is calcium carbonate caco3. Is marble clastic chemical or organic.

All that is required is some combination of high temperature and high pressure enough time for the recrystallization to take pl. A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering. It is an igneous volcanic rock. Never has been alive.

Non clastic or chemical rock is composed of chemical precipitate out of solution. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Marble is a metamorphic rock. Iı belongs to the family of pelitic rocks clays 0 02 mm the fine particles in water sales and a carbonate is a variety of mudstone.

None of the above.
