What Is Marble A Clastic Rock

Clastic rock is formed from particles of other rock.

What is marble a clastic rock.

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

Where the volcanic material has been transported and reworked through mechanical action such as by wind or water these rocks are termed volcaniclastic. 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. In general the greater the distance traveled the smaller and more rounded the sediment particles will be.

The word breccia has an italian origin and means stone made of cemented gravel. What is the difference between clastic and non clastic. Clastic rocks are composed largely of quartz feldspar rock lithic fragments clay minerals and mica. This is a reflection of the great variation in mineral composition texture and other properties of these rock types.

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 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. 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. Commonly associated with unsieved volcanic activity. Pyroclastic rocks or pyroclastics derived from the template lang el meaning fire. 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.
