What Is Marble A Clastic Rock

The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together.

What is marble a clastic rock.

Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment table grain size is largely a function of the distance the particle was transported. Marble is a metamorphic rock. A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering. Where the volcanic material has been transported and reworked through mechanical action such as by wind or water these rocks are termed volcaniclastic.

Commonly associated with unsieved volcanic activity. The word breccia has an italian origin and means stone made of cemented gravel. None of the above. In general the greater the distance traveled the smaller and more rounded the sediment particles will be.

What is the difference between clastic and non clastic. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. Breccia is a sedimentary rock made up of angular particles over two millimeters in diameter clasts with the spaces between the particles filled with smaller particles and mineral cement matrix. Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments over two millimeters in diameter.

This is a reflection of the great variation in mineral composition texture and other properties of these rock types. Pyroclastic rocks or pyroclastics derived from the template lang el meaning fire. Clastic rock is formed from particles of other rock. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Any type of mineral may be present but they in general represent the minerals that exist locally. Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals. Noncarbonate chemical sedimentary rocks differ in many respects from carbonate sedimentary rocks and terrigenous clastic sedimentary rocks and there is no single classification that has been universally accepted.
