clastic rock
Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains
Yes, lunar regolith breccia can contain both crystalline rock fragments and glassy fragments. Crystalline rock fragments are typically from the Moon's crust or mantle, whereas glassy fragments are often formed from impact events that melt and rapidly cool the materials. These fragments provide valuable information about the Moon's history and geological processes.
A sedimentary rock composed of large chunks is called a conglomerate. It is formed from the consolidation and lithification of rounded gravel and pebble-sized rock fragments. These rock fragments are held together by a matrix of sand, silt, or clay.
Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
A clastic rock.
sedimentary
A rock formed from deposits of shell fragment is Limestone.
Sedimentary rock
A sedimentary rock is formed when rock fragments are compacted and cemented together by pressure and minerals. Examples of sedimentary rocks include sandstone, shale, and conglomerate.
clastic rock
Fragmental sedimentary rocks are formed from rock fragments, such as sand, gravel or clay. These fragments become cemented together because of pressure and other chemical reactions.
conglomerate
sedimentary rock
The resulting sedimentary rock is classified as clastic.
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
Sedimentary rock is formed when small rock fragments are cemented together. This happens through a process called lithification where sediments are compacted and cemented together over time. Sandstone and conglomerate are examples of sedimentary rocks formed in this way.
