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 Rock - Pictures, Definition & More - Geology.com
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.
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.
Diorite : Properties, Formation, Composition and Uses - Geology …
2023年8月21日 · 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: A Salt-and-Paper Looking Coarse-Grained Rock
2023年6月27日 · Diorite is a coarse-grained, intermediate plutonic, or intrusive igneous rock. It has mainly plagioclase feldspar, biotite, hornblende, sometimes pyroxenes, and other minerals. This rock’s composition lies between gabbro, a mafic rock, and granite, a felsic rock with 52-63 wt.% silica content.
Diorite: Identification, Characteristics, Pictures & More
Diorite is an intrusive igneous rock composed primarily of plagioclase feldspar and smaller amounts of mafic minerals like hornblende and biotite. It has a phaneritic texture, meaning its interlocking crystals can be seen with the naked eye. It is known for having a characteristic ‘salt and pepper’ appearance.
Diorite: Composition, Properties, Occurrence, Uses - Geology In
Diorite is a geologically significant igneous rock offering insights into the processes shaping the Earth's crust. Its characteristic mineralogical composition and intrusive origin make it a valuable tool for geologists in understanding past tectonic events.
Diorite - ALEX STREKEISEN
Diorite is a coarse-grained, intrusive igneous rock that is intermediate in composition between granite and gabbro. Diorite is composed primarily of plagioclase feldspar, amphibole, and pyroxine minerals with small amounts of biotite mica.
What is Diorite? - WorldAtlas
2017年12月1日 · An igneous rock formed by subterranean crystallized magma, Diorite is composed of plagioclase feldspar, quartz, hornblende, pyroxene and biotite. Varieties that lack hornblende are referred to as "leucodiorite".
Gabbro vs. Diorite — What’s the Difference?
2024年5月9日 · Diorite ( DY-ə-ryte) is an intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is intermediate in composition between low-silica (mafic) gabbro and high-silica (felsic) granite.
