The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals. Magmas ...

Igneous minerals within a pluton can record deformation history. Therefore, it is useful to understand magmatic fabrics for understanding pluton emplacement. Experimental work done on rocks has helped ...

The rewards of climbing Moxie Mountain are so worth the effort, and then there's so much more to enjoy in this remote area.

Granite - Granite is coarse-grained, plutonic igneous rock, typically rich in quartz and feldspars. Graptoloidea - Graptolites were minute individual tube-shaped animals grouped together into colonies ...

Igneous rocks form from the solidification of molten rock material called magma. This process can occur either below the ...

A close approach to this ideal situation is common in igneous rocks, particularly plutonic ones, and even when equilibrium is not achieved, mineral assemblages can still be understood in terms of ...

Oh, and Pluto—that’s not a planet ... systems capable of isolating slivers of continental crust within the new igneous crust.

Abstract: Apatites crystallized from different types of igneous rocks show significant variations in ... separated from three principal rock types of the Transhimalayan igneous plutonic suite: S-type ...
