What is the mineral with crystals that breaks into flat sheets?
Mica is crystalline and forms layers.
A foliated metamorphic rock forms when crystals what?
Foliated metamorphic rocks exhibit a layering affect with parallel layers of mineral crystals one on top of the other. A good example of this is gneiss, which has alternating layers of light and dark minerals. Foliation takes place when pressure is applied to crystals and they recrystallize or align themselves at right angles to the direction of the applied directional stress.
Is flint intrusive or extrusive?
Flint is a chemical sedimentary rock formed from the precipitation of silica rich solutions in layers of marine sediments.
Can a rock that is changed by metamorphism have crystals in parallel layers?
Yes
A metamorphic rock with visible layers or bands is said to be what?
Visible layers or bands in metamorphic rock is designated as 'foliation' and the rock is said to be 'foliated'.
Is rock with visible layers and no visible mineral crystals likely to be formed from lava hardening on Earth's surface?
Probably not. While layered lava flows are not uncommon, most layered rocks formed from the accumulation and lithification of sediment.
What are the source materials for the ingredients of sedimentary rocks?
Some minerals in sedimentary rocks include halite mineral crystals which are in rock salt and gypsum mineral crystals which are in rock gypsum. Also, calcite crystals are found in oolitic limestone and travertine.
What is the mineral with crystals that breaks into flat sheets?
Mica is crystalline and forms layers.
A rock has alternating layers of dark and light colors the rock has visible quartz crystals and does not contain any fossils where was this rock most likely formed?
deep under the earth
What is a mineral alignment?
A mineral alignment is a layered arrangement of firmly joined crystals of minerals; the minerals are aligned in layers or bands.
What are rocks that have visible layers and elongated mineral grains?
Maybe Sedimentary Rocks?
Is a rock with visible layers and no minerals likely to have formed lava hardening on Earth's surface?
yes
What is the hue or appearance of a mineral?
The definition of hue is color. Appearance could also relate to color, or if the mineral has cleavage or is fractured. Cleavage refers to the formation of a mineral in layers, and fracture is when a mineral has no specific formation pattern. These characteristics are visible. How a mineral appears is what it looks like.
What is metamorphic rock in which mineral crystals are arranged in parallel layers or band?
They are called foliated metamorphic rocks.
What is a rock's texture?
The texture of a rock consists of it's grain or mineral crystal size, the arrangement of the grains or crystals, and the degree of uniformity of the grains or crystals. Examples of rock texture would be: * Coarse grained--visible crystals or grains as in granite. * Fine grained--small grains, invisible to the unaided eye as in shale. * Porphyritic--large visible crystals in a fine grained matrix as in granite porphyry. * Schistose--layers of flattened micaceous minerals such as in mica schist. * Foliated--a metamorphic rock texture of parallel mineral banding as in gneiss. * Homogenous--same grain apperance in all directions as in basalt.
A foliated metamorphic rock forms when crystals what?
Foliated metamorphic rocks exhibit a layering affect with parallel layers of mineral crystals one on top of the other. A good example of this is gneiss, which has alternating layers of light and dark minerals. Foliation takes place when pressure is applied to crystals and they recrystallize or align themselves at right angles to the direction of the applied directional stress.
What is it called when rock forms of small pieces of other rocks are deposited in layers and are cemented together by disolved mineral material?
rock formed of small rocks that are cemented together by dissolved mineral material?
