İngilizce - İngilizce
a metamorphic rock consisting of interlocking grains of quartz
- a rock composed of quartz grains cemented with silica
hard metamorphic rock consisting essentially of interlocking quartz crystals
Sandstone that has been converted into a solid quartz rock. Quartzites are usually white; they fracture smoothly and break up into rubble under frost action. Sandstone may be converted to quartzite by precipitation of silica from waters below the Earth's surface; such rocks are called orthoquartzites, whereas those produced by recrystallization (metamorphism) are metaquartzites. Because they weather slowly, they tend to project as hills or mountain masses. Many prominent ridges in the Appalachian Mountains are composed of quartzite. Pure quartzites are a source of silica for metallurgical purposes and for the manufacture of silica brick. Quartzite is also quarried for paving and roofing materials
A crystalline rock formed mainly of quartz
{i} metamorphic rock mainly composed of quartz
metamorphosed sandstone
A stone which was formed in water deposited sediments and consists of sand grains which have been cemented together It can be chipped, but is difficult to work
Massive quartz occurring as a rock; a metamorphosed sandstone; called also quartz rock
The characteristic product of the metamorphism of a siliceous sandstone or grit The term is also used to denote sandstones and grits which have been cemented by silica
A quartz rock that has metamorphic d from sandstone; used by miners to describe any drillresistant sandstone
A compact granular rock composed of quartz It is a metamorphosed sandstone, and siliceous cement is often so blended with the quartz grains as to give the rock a nearly homogeneous texture Primary materiel in silica brick
Quartz-rich sandstone that has been metamorphosed
A metamorphic rock formed from pure quartz sandstones
Generalized term for a sandstone that has been recrystallized or cemented (see orthoquartzite and metaquartzite)
A very hard, unmetamorphized sandstone that consists primarily of quartz grains that have been cemented together with secondary silica so that the rock breaks across or through the grains rather than around them
A granular form of quartz stone which was formed in water deposited sediments and consists of sand grains which have been cemented together It can be chipped, but is difficult to work
A compact granular rock composed of quartz metamorphism It is an extremely hard, fine- to coarse-grained massive rock that forms from sandstone
A sandstone recrystallized by metamorphism
is a metamorphic rock that results from the metamorphism (heat and pressure) of the sedimentary rock quartz sandstone
