Feldspar
Feldspar processors reported co-product recovery of mica and silica sand. Feldspar is mined from large granite bodies (called plutons by geologists), from pegmatites (formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vapor-rich pockets that allow the growth of extremely large crystals), and ...

Silica | The Canadian Encyclopedia
Silica. Silica, or silicon dioxide (SiO 2), occurs as the MINERAL quartz and is the most abundant mineral of the Earth's crust. It also occurs in the skeletal parts of some animals (eg, certain protozoa) and various plants. Quartz forms hexagonal crystals and melts at 1723°C; it has a low thermal coefficient of expansion and is very resistant to …

6.1 Clastic Sedimentary Rocks – Physical Geology
The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.

Basalt
Basalt is a fine-grained and dark-colored rock. Black color is given to basalt by pyroxene group mineral augite. Width of the sample is 12 cm. Basalt is usually black or dark gray and relatively featureless. It is composed of mineral grains which are mostly indistinguishable to the naked eye. Basalt may also contain volcanic glass.

Magma's Role in the Rock Cycle
Magma is a molten and semi-molten rock mixture found under the surface of Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases. When magma is ejected by a volcano or other vent, the ...

Silica, Crystalline
Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure ...
