A clastic texture refers to sedimentary rocks made up of fragments of pre-existing rocks that have been broken down, transported, and then deposited. These fragments, called clasts, can vary in size and are typically held together by a cementing material such as silica, calcite, or clay minerals. Clastic textures are commonly found in sandstone, conglomerate, and shale rocks.
What else can I help you with?
Is gneiss clastic organic or chemical?
None of the above. These terms describe sedimentary rocks. Granite is igneous.
When large masses of magma solidify far below earth's surface they form igneous rocks that have what kind of texture?
Igneous rocks formed from large masses of magma solidifying far below Earth's surface typically have a coarse-grained texture. This is because the slower cooling process allows larger mineral crystals to form within the rock.
What type of rock is clastic and non-clastic?
Clastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock. Non-clastic sediments are made up of dissolved minerals or organic matter.
What are three of clastic sedimentary rocks?
Shale, sandstone, and conglomerate are examples of clastic sedimentary rock.
Is conglomerate clastic organic or chemical rock?
Conglomerate is a clastic rock. They are coarse-grained sedimentary rocks.
Would texture or composition be more important to classify a clastic sedimentary rock?
composition
How do clastic rocks differ from non-clastic rocks in terms of process of formation?
Clastic rocks are composed of broken pieces of older rocks that have been broken up by the process of weathering and are therefore sedimentary in nature. The "clasts" (bits of older rock) may vary in size.
How does one clastic detrital sedimentary rock have a texture and composition different than another?
Different clastic sediments have different textures based on the size, shape, and sorting of the grains they are composed of. The composition of a clastic sedimentary rock will vary depending on the mineralogy of the grains present in the rock. Factors such as the source rock, transportation distance, and depositional environment can all contribute to the differences in texture and composition between clastic sedimentary rocks.
What kind of texture will a sandstone rock have?
Sandstone will have a gritty clastic texture, created by the cemented particles of sand sized particles of rock. You should be able to see the individual sand grains.
What texture refers to rocks composed mainly of mineral and volcanic fragments?
The texture that refers to rocks composed mainly of mineral and volcanic fragments is known as "clastic texture". This texture is characterized by the presence of distinct particles or fragments that are cemented together to form the rock.
Which rock has a clasic texture......... a rock salt b gypsum c marble d sandstone?
You probably mean clastic. In that case: Sandstone.
What besides size and position determines clastic sedimentary rock texture?
Clastic sedimentary rock texture is also influenced by factors such as mineral composition, sorting (uniformity of particle size), rounding (degree of edges and corners), and grain angularity (shape of grains). These factors can provide information about the energy of the environment where the rock was formed.
Is chalk clastic or non clastic?
Chalk is non-clastic, as it is primarily composed of the mineral calcite (calcium carbonate) formed from the remains of microscopic marine organisms such as plankton. These organisms contribute to the fine-grained texture of chalk through chemical precipitation rather than mechanical weathering or erosion.
Difference between clastic rocks and non-clastic rocks?
Clastic rocks are sedimentary rocks consisting of bits and pieces of other rocks created by physical/mechanical weathering. Non-clastic are also sedimentary rocks; however are absent bits and pieces of other rocks and are formed through chemical processes (e.g. hydrolysis, evaporation, precipitation, oxidation) or form out of organic material (e.g. coal, chalk).
Is breccia chemical clastic or organic?
clastic
Is chalk clastic chemical or organic?
It is clastic
What is an example of a medium-grained clastic sedimentary rock?
Sandstone is an example of a medium-grained clastic sedimentary rock. It is composed of sand-sized particles that are typically visible to the naked eye, giving it a medium-grained texture. Sandstone forms from the accumulation and cementation of sand grains.
