Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
These terms refer to the crystalline structure of the minerals that are present in a body of rock. Rocks with an interlocking mineral structure have formed from melt or from recrystallization and therefore are igneous or metamorphic. Their crystals have formed in a set order of crystallization, filling the spaces fully between them. Examples are granite, basalt, schist, and phyllite. Non-interlocking rock structures are usually clastic sedimentary rocks, which are formed from the compaction and cementation of rock particles of various types. Compaction and cementation will leave air and fluid spaces between rock particles which, although cemented together, are not interlocking. Examples are sandstone, limestone, and shale.
== Talc is a mineral. == True... but Talc is a Metamorphic rock. == Actually it is a metamorphic mineral, not a rock.
Phyllite is a metamorphic rock.
Diamond is a mineral form of carbon. It is not a metamorphic rock, but a mineral formed from extreme heat and pressure.
Cobalt is a mineral, not a rock.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Metamorphic rocks that consist of only one mineral and have large interlocking crystals often have a coarse-grained texture. This means that the individual mineral grains are easily visible to the naked eye. Examples of such rocks include quartzite (formed from quartz) and marble (formed from calcite).
Mineral crystals in rock can be interlocked when forming or metamorphosed, or simply cemented together. Rocks with interlocking crystals tend to resist breakage by a force better than cemented rock.
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Granite is composed of interlocking mineral crystals of quartz, micas, and feldspars mainly.
Rocks are normally composed of interlocking mineral crystals or clasts. It is rare for metamorphic rocks to be porous and as such there is likely to be very little if any air in them. An example of a very porous rock due to the presence of gasses coming out of solution from a lava is pumice.
Foliation
Nonfoliated rock
They are called foliated metamorphic rocks.
In all three rock types: igneous, sedimentary, and metamorphic. By definition, a mineral has a crystalline structure, and rocks are composed of combinations of minerals. Rocks with interlocking crystalline mineral structures are usually igneous or metamorphic.
Non-foliated metamorphic rock is composed of non-layered visible mineral crystals.
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
