Diorite: Igneous Rock - Pictures, Definition & More - Geology.com
What is Diorite? Diorite is the name used for a group of coarse-grained igneous rocks with a composition between that of granite and basalt. It usually occurs as large intrusions, dikes, and sills within continental crust. These often form above a convergent plate boundary where an oceanic plate subducts beneath a continental plate.

Aug 21, 2023 · Definition of Diorite: Diorite is a coarse-grained igneous rock that falls within the plutonic category, meaning it forms deep beneath the Earth’s surface through the cooling and solidification of magma. It is primarily composed of plagioclase feldspar, …
Diorite - Wikipedia
Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene.
Diorite | Igneous, Intrusive, Plutonic | Britannica
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 Rocks: Identification, Characteristics, Pictures, and More
Mar 31, 2024 · Diorite rocks form through a complex process involving the cooling and solidification of magma deep within the Earth’s crust. This formation process is intricately tied to the geological history of the Earth, shaping the characteristics of diorite rocks. Here’s a deeper look at how diorite rocks are formed: Magma Intrusion:
Diorite: Composition, Properties, Occurrence, Uses - Geology In
Diorite is an intrusive, coarse-grained, igneous rock, meaning it forms from the slow cooling and solidification of magma (molten rock) underground. Diorite is typically composed of plagioclase feldspar, hornblende, biotite, and/or pyroxene minerals. Plagioclase feldspar is a type of feldspar that is rich in sodium and calcium.
