How can mineral quartz be in an igneous and sedimentary rock?
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
What are rocks that have a glassy texture called?
Obsidian
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
What is the occurrence of quartz?
*volcanic rocks*jewelry*mountains
What are the 3 kinds of rocks?
Sedimentary, Igneous and Metamorphic.
Is amethyst igneous metamorphic or sedimentary?
Amethyst is a variety of quartz, which is a mineral that is formed in igneous and metamorphic rocks. Amethyst is typically formed in hydrothermal veins within igneous rocks or as a product of metamorphism in rocks rich in silica. Therefore, amethyst is not classified as a specific rock type, but rather a mineral that can be found in both igneous and metamorphic rocks.
How are igneous rocks classified acording to their..?
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Rocks that originated from the liquid phase are classified as?
Igneous rocks are classified as rocks that originated from the liquid phase, specifically from the cooling and solidification of magma or lava.
What two rocks are found in the outer core?
igneous quartz
How are rocks physically classified?
they are classified into 3 major kinds of rocksthey are the ;IGNEOUS ROCKS,SEDIMENTARY ROCKS,AND METAMORPHIC ROCKS
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
Is milky quartz a igneous metamorphic or igneous rock?
milky quartz is either metamorphic or igneous
How does quartz get into rocks?
Quartz is commonly found in many types of rocks, including igneous, metamorphic, and sedimentary rocks. It forms from the crystallization of silica-rich magma in igneous rocks, from the alteration of pre-existing minerals in metamorphic rocks, and from the cementation of grains in sedimentary rocks. Quartz can also be deposited as a vein or replacement mineral in existing rocks.
What rocks are classified as?
Mantle rock is classified as ultramafic igneous rock.
What do volcanic rocks and plutonic rocks have in common?
Both volcanic rocks and plutonic rocks are types of igneous rocks formed from the cooling and solidification of molten materials (magma or lava). They both contain minerals such as quartz, feldspar, and mica. Additionally, both types of rocks can be classified based on their texture, composition, and mineral content.
How could the mineral quartz be in an igneous rock and sedimintary rock?
Quartz can be present in igneous rocks if it crystallizes from magma during the cooling process. In sedimentary rocks, quartz can be derived from the weathering and erosion of pre-existing rocks rich in quartz, transported and deposited as sediment, and then cemented together to form the sedimentary rock.
Igneous rocks that result when lava solidifies are classified as what?
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
