Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene.The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic granite.

Igneous rock compositions: This chart illustrates the generalized mineral composition of igneous rocks. It shows that diorites and andesites are composed mainly of plagioclase feldspar, amphiboles, and micas; sometimes with minor amounts of orthoclase, quartz, or pyroxene.

2023年8月21日 · Diorite is an intriguing igneous rock that holds a significant place in the world of geology, art, and construction. Its unique combination of minerals, textures, and appearances has captivated scientists, artists, and builders for centuries.

Discover the properties, formation, and uses of diorite, a coarse-grained igneous rock known for its durability and distinctive salt-and-pepper appearance. Learn about its types, sourcing locations, and how to care for diorite in this detailed guide.

Diorite, medium- to coarse-grained intrusive igneous rock that commonly is composed of about two-thirds plagioclase feldspar and one-third dark-coloured minerals, such as hornblende or biotite. The presence of sodium-rich feldspar, oligoclase or …

Diorite Composition. Diorite is an igneous rock classified as an intermediate intrusive (plutonic) rock based on its geochemical composition. This translates to a position between felsic rocks (high silica content) and mafic rocks (low silica content).

Diorite is a fairly common rock type, but many people have never even heard of it. Chances are good that you have seen and touched diorite many times in your life, whether or not you were aware of it at the time.
