Rocks, substances made of varying minerals and elements, vary in size, shape, and texture. These are classified three different ways. They are either sedimentary, igneous, or metamorphic. Answer and Explanation:1 Granite is an igneous rock. Igneous rock is rock that has formed from magma that ...
Obsidian and pumice are igneous rocks that solidified so rapidly from a melt that their atoms were unable to move into an ordered atomic structure. Instead, they rapidly formed a random network of atoms known as a "glass." Obsidian and pumice are amorphous, and their compositions can vary dra...
What is Obsidian? Obsidian Rock Color:Deep black or blackish green Fracture:Conchoidal Mohs scale hardness:5 – 6 Luster:Vitreous Specific gravity:c. 2.4 Optical properties:Translucent Obsidian is a volcanic glass that occurs naturally as an extrusionaryigneous rock. ...
Green Obsidian Properties Category:Igneous rock, specifically a volcanic glass formed from rapidly cooled lava. Color:Deep emerald green, sometimes with a subtle sheen or iridescence. The color variations can range from near black with green flashes to a vibrant, almost apple-green hue. ...
There are three basic groups: Obsidian Igneous Rock Fossilicious Limestone Sedimentary Rock Gneiss Metamorphic Rock Coal Biogenic Rock igneous-rocks created by volcanic activity. sedimentary-rocks created by weathering and cementing back together and metamorphic-rocks created by heat and pressure...

Flood basalts are pretty much the most mineralogically undeveloped igneous rock on the planet. If you’re lucky you will find some peridot (but not likely) and that is about it. This means there is no Lamproite or Kimberlite from which one can get diamonds. There are no diamond-bearing ...
What type of igneous rock is andesite? Andesite is afine-grained, extrusive igneous or volcanic rock. It is dark grey and made up of equal amounts of light and dark minerals, although the crystals are too small to be seen without a magnifier. Occasionally andesite may contain some larger ...
