Diabase is composed of plagioclase feldspar (mostly labradorite) and pyroxene ().The crystals that make up dolerite are usually visible to the naked eye, but sometimes porphyritic rocks of basaltic composition with pyroxene and especially plagioclase phenocrysts are also named that way. Ophitic texture (randomly oriented plagioclase laths enclosed by pyroxene grains) is a characteristic ...

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.

Plagioclase minerals are hard, non-metallic minerals that exhibit two cleavage directions that meet at nearly right angles. The name 'plagioclase' refers to this cleavage pattern, coming from the Greek words for 'oblique' (plagios) and 'to break' (klasis).Apart from pegmatites, the plagioclase minerals seldom occur as well-defined isolated crystals, but instead occur as blocky to ...

The uses and properties of the mineral Barite. Barite Occurrence. Barite often occurs as concretions and void-filling crystals in sediments and sedimentary rocks.It is especially common as concretions and vein fillings in limestone and dolostone.Where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes found at the soil-bedrock contact.
