diorite |
Also found in: Dictionary/thesaurus, Wikipedia, Hutchinson | 0.03 sec. |
dioriteMedium- to coarse-grained igneous rock that commonly is composed of about two-thirds plagioclase feldspar and one-third dark-coloured minerals, such as hornblende or biotite. Diorite has about the same structural properties as granite but, perhaps because of its darker colour and more limited supply, is rarely used as an ornamental building material. It is one of the dark gray stones that is sold commercially as “black granite.” How to thank TFD for its existence?

Gold mineralization at Lindero is intrusive-hosted within a dioritic porphyry. Drill Holes R05-03 (230az/-55dip) and R05-04 (042az/-45dip) were collared to test the southwest trending contact zone between ultramafic intrusive unit to the southwest and dioritic intrusive and Takla volcanic rocks to the northeast. The Red Property is a copper-gold porphyry prospect characterized by a northwest trending structural corridor that controls the emplacement of a broad dioritic intrusive complex where copper-gold mineralization is associated with diorite-porphyry dykes that cut older Takla Group volcanic rocks. |
