What Is Marble A Clastic Rock

What is the difference between clastic and non clastic.

What is marble a clastic rock. In general the greater the distance traveled the smaller and more rounded the sediment particles will be. Where the volcanic material has been transported and reworked through mechanical action such as by wind or water these rocks are termed volcaniclastic. The word breccia has an italian origin and means stone made of cemented gravel. 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.

This is a reflection of the great variation in mineral composition texture and other properties of these rock types. Commonly associated with unsieved volcanic activity. Clastic terrigenous sedimentary rocks consist of rock and mineral grains or clasts of varying size ranging from clay silt and sand up to pebble cobble and boulder size materials. 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. 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. The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together. 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.

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. Any type of mineral may be present but they in general represent the minerals that exist locally. None of the above. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Pyroclastic rocks or pyroclastics derived from the template lang el meaning fire. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments over two millimeters in diameter. Clastic rock is formed from particles of other rock.
