What type of rock is White to gray medium soft fine grained rock?
The rock described is likely to be shale, which is a sedimentary rock composed of clay minerals. Shale is typically white to gray in color, medium soft in texture, and fine-grained.
Which 2 groups is broken down into smaller groups by grain size?
Sedimentary rocks and igneous rocks can be broken down into smaller groups based on grain size. In sedimentary rocks, grain size categories include clay, silt, sand, and gravel. In igneous rocks, grain size categories include fine-grained, medium-grained, and coarse-grained.
What is meaning the grain of the rock?
fine grained or coarse grained
WHAT IS A FOLIATED METAMORPHIC ROCK WITH MEDIUM TO COARSE GRAINED CRYSTALS AND WHOSE PARENT ROCK?
A foliated metamorphic rock with medium to coarse-grained crystals is typically schist. Schist is characterized by its well-developed foliation and often contains visible mineral grains, such as mica, garnet, or quartz. Its parent rock is usually shale or mudstone, which undergoes metamorphism under heat and pressure, leading to the alignment of minerals and the development of foliation.
What is the grain size of welded tuff?
The grain size of welded tuff can vary depending on the specific conditions under which it was formed. Generally, welded tuff has a fine-grained to medium-grained texture due to the rapid cooling and solidification of the volcanic ash during welding. This process can result in a range of grain sizes, typically ranging from less than 1 millimeter to several millimeters in size.
Fine grained medium grained and coarse grained what are these?
I'm not too sure
Is quartzite rock fine grained course grained or medium grained?
Coarse
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.
What is a type of medium-grained clastic sedimentary rock?
sandstone
What lists the rocks in order of increasing grain size and increasing grade of metamorphism?
The list that orders rocks in increasing grain size and increasing grade of metamorphism is: shale (fine-grained) - slate (fine-grained) - phyllite (medium-grained) - schist (medium to coarse-grained) - gneiss (coarse-grained).
Which is an example of a medium-grained clastic sedimentary rock?
Sandstone is an example of a medium-grained clastic sedimentary rock. It is formed from the accumulation and cementation of sand-sized grains (0.06–2mm) of mineral, rock, and organic particles.
What is the texture of amphibolite?
Amphibolite typically has a medium to coarse-grained texture with a foliated structure. It consists mainly of amphibole minerals such as hornblende, which gives it a dark color and a shiny appearance.
What type of rock is White to gray medium soft fine grained rock?
The rock described is likely to be shale, which is a sedimentary rock composed of clay minerals. Shale is typically white to gray in color, medium soft in texture, and fine-grained.
Is diorite a coarse grained rock?
Yes, diorite is a coarse-grained igneous rock that typically contains a mixture of light and dark minerals. It forms from the slow cooling of magma deep within the Earth's crust, resulting in visible crystals that are larger than those in fine-grained rocks.
What are three types of sedimentary rock texture?
Three types of sedimentary rock texture are clastic (made of broken fragments), crystalline (formed from the precipitation of minerals), and biogenic (composed of organic material such as shells or plant remains).
What is a medium grained rock?
A medium-grained rock is a type of igneous, sedimentary, or metamorphic rock characterized by mineral grains that are roughly between 0.25 mm and 2 mm in size. Examples include granite, which has visible crystals, and sandstone, which consists of sand-sized particles. The size of the grains typically indicates the cooling history of the rock; medium-grained rocks often form in environments where the cooling rate is moderate. Their texture can affect their physical properties and how they are used in construction and other applications.
What does dolerite mean?
A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.
