The name diorite (from Ancient Greek διορίζειν, "to distinguish") was first applied to the rock by René Just Haüy [10] on account of its characteristic, easily identifiable large crystals of hornblende. [4] Dioritoids form a family of rock types similar to diorite, such as monzodiorite, quartz diorite, or nepheline-bearing diorite ...
Hornblende diorite from the Henry Mountains, Utah, US. Hornblende is a common constituent of many igneous and metamorphic rocks such as granite, syenite, diorite, gabbro, basalt, andesite, gneiss, and schist. It crystallizes in preference to pyroxene minerals from cooler magma that is richer in silica and water. [13]
The way a mineral splits (or “cleaves”), particularly along planes in the crystal structure. Cleavage is generally described by. how well a mineral can be split to produce a flat plane, a process controlled by planes of weakness in the crystal structure. the number of distinct directions of these cleavage planes; the angles between those ...

Another feature of these rocks is the presence of large foreign crystals, or xenocrysts, of feldspar and of quartz. Their forms are rounded, indicating partial resorption and the quartz may be surrounded by corrosion borders of minerals such as augite and hornblende produced where the magma is attacking the crystal.
A fluid inclusion is a bubble of liquid and/or gas that is trapped within a crystal. As minerals often form from a liquid or aqueous medium, tiny bubbles of that liquid can become trapped within the crystal, or along healed crystal fractures. These inclusions usually range in size from 0.01 mm to 1 mm and are only visible in detail by ...
The name comes from two related rocks to which granodiorite is an intermediate: granite and diorite. The gran-root comes from the Latin grānum for "grain", an English language derivative. Diorite is named after the contrasting colors of the rock.
Generally, however, these guidelines agree that highly processed foods contain high amounts of total and added sugars, fats, and/or salt, low amounts of dietary fiber, use industrial ingredients ...
