What Is Marble A Clastic Rock

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.

What is marble a clastic rock.

Where the volcanic material has been transported and reworked through mechanical action such as by wind or water these rocks are termed volcaniclastic. A clast is a fragment of geological detritus chunks and smaller grains of rock broken off other rocks by physical weathering. What is the difference between clastic and non clastic. Pyroclastic rocks or pyroclastics derived from the template lang el meaning fire.

The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together. 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. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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. And template lang meaning broken are clastic rocks composed solely or primarily of volcanic materials. This is a reflection of the great variation in mineral composition texture and other properties of these rock types.

None of the above. In general the greater the distance traveled the smaller and more rounded the sediment particles will be. 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. 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. The word breccia has an italian origin and means stone made of cemented gravel. Marble is a metamorphic rock. Any type of mineral may be present but they in general represent the minerals that exist locally.
