- Orbicular diorite from Corsica (corsite). QAPF diagram with dioritoid fields highlighted in yellow and diorite in red. Mineral assemblage of igneous rocks.
- Diorite is a block of igneous rock, found in large pockets in the ground. Polished diorite is the polished version of diorite.
- As diorite is an intrusive rock, it forms beneath the Earth’s surface when trapped magma slowly cools, crystallizing deep in the Earth’s crust.
- Diorite is coarse grained intrusive igneous rock that commonly mineralogy is plagioclase feldspar and dark colored minerals such as hornblende and biotite.
- Diorite (red) on the QAPF diagram. Diorite in the wider sense (yellow) includes adjacent fields of quartz diorite, quartz monzodiorite, monzodiorite, foid-bearing...
- If there is more mica, the diorite will be darker in color. Some examples of diorite include: -Gabbro: A type of diorite that contains a high ratio of mica.
- Diorite is an intrusive, coarse-grained, igneous rock, meaning it forms from the slow cooling and solidification of magma (molten rock) underground.
- The streak of Diorite is bluish black whereas its fracture is not available. Luster of Diorite is the interaction of light with the surface of Diorite.
- In the field and in common practice, most dioritoids are simply referred to simply as ‘diorite’. Quartz is almost entirely absent from true diorite.
- Diorite rock has a contrasting mix of black and white mineral grains. ... Diorite accepts a bright polish and can be attractive as a gemstone.
