Granite is a coarse-grained, light-colored igneous rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. At this stage, the liquid will begin to crystallize another phase (so that there are two solids and a liquid in equilibrium along the curve). [email protected] But it is clear that many apparently trivial differences tend regularly to recur, and have a real significance, and so long as any variation can be shown to be of this nature it deserves recognition.

Metamorphic rocks may be classified on the basis of foliation into two types. ), Magmatism in the Ocean Basins. 2010 – Aug. Such variation results from the replacement of one ion or ionic group by another in a particular structure. m is the magma temperature (1500K), T. Mineral modes. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Textural variations correlate well with the topographic features: the higher the elevationthe more aphanitic the Blue.

The main purpose of showing this diagram here is to illustrate how widely natural silicate magmas can vary in their composition: SiO2 contents range from 31% to 76%, and total alkali contents vary from 1% up to 15%. To some extent, the choice of which variation diagrams to plot depends on what specific petrologic questions (hypotheses) you are asking of the data. petrology, branch of geology specifically concerned with the origin, composition, structure, and properties of rocks rock, aggregation of solid matter composed of one or more of the minerals forming the earth's crust. Miarolitic cavities are numerous in some places. Vesicular igneous rocks, such as pumice, look bubbly and form before gases are able to escape as lava forms the rock.
