What Is Marble A Clastic Rock

Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals.

What is marble a clastic rock.

Any type of mineral may be present but they in general represent the minerals that exist locally. The word breccia has an italian origin and means stone made of cemented gravel. Commonly associated with unsieved volcanic activity. Clastic rock is formed from particles of other rock.

Marble is a metamorphic rock. None of the above. Where the volcanic material has been transported and reworked through mechanical action such as by wind or water these rocks are termed volcaniclastic. What is the difference between clastic and non clastic.

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. 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. The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together. 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. A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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.

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. 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. Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments over two millimeters in diameter. And template lang meaning broken are clastic rocks composed solely or primarily of volcanic materials.
