Impact Of the rocks exposed at the Earth's surface, approximately 90 percent constitute silicates. Approximately a quarter of that rock is intrusive–for example, granite–a quarter is extrusive–volcanic–and the other half is metamorphic and "Precambrian"–a period of time that extends from abou...
Granite is acoarse-grained rockcomposed of aluminosilicate minerals that crystallizes slowly and at much higher temperatures than basalt. What are the 3 major types of lava? The high temperatures and pressure under Earth's crust keep magma in its fluid state. There are three basic types of magma...

black color to the obsidian. Most black obsidians contain magnetite, an iron oxide, nanoinclusions, the composition of obsidian is extremely felsic. Obsidian mainly consists of SiO2 (silicon dioxide), usually 70% or more. Crystalline rocks comprise granite and rhyolite with the composition of ...
The origin of these poorly stratified quartzofeldspathic rocks has been controversial since they were first named more than a century ago. They have variously been called granite, metagraywacke, wildflysch, boulder gneiss, migmatite, metadiamictite, olistostrome, and sedimentary melange, among ...
Basalt is the dark, heavy volcanic rock that makes up most of the world's oceanic crust. Some of it erupts on land, too, but to a first approximation, basalt is an oceanic rock. Compared to the familiar granite of the continents, basalt ("ba-SALT") is darker, denser and finer graine...
By contrast, the southern margin of the Asian plate (south Lhasa block) shows a very different evolution, being dominated by the pre-collision Gangdese composite I-type granite batholith, together with its extrusive calc-alkaline equivalent, the Linzizong volcanics (e.g. Chung et al., 2005,...
