Kimberlite tailings doubtful at best that it could ever be used as a construction material. In fact kimberlite exposed to water or air will alter to serpentine soil with very fine particles extremely fast. Some mines use this characteristic and stockpile kimberlite ore in outside pits and after a couple of years it can then be processed without any crushing hence better preserving the diamonds it contains. New process is described for the preparation of free flowing hydrated amorphous silica from kimberlite tailing. The process comprises treating of kimberlite with acid, further reacting it with alkali solution to obtain soluble metal silicate
Types of volcanic eruptions general mass behind it moves forward. Pahoehoe lava can sometimes become A'a lava due to increasing viscosity or increasing rate of shear, but A'a lava never turns into pahoehoe flow. Hawaiian eruptions are responsible for several unique volcanological objects. Small volcanic particles are carried and formed by the wind, chilling quickly into teardrop-shaped glassy fragments known as Pele's tears (after Pele, the Hawaiian volcano deity). During especially high winds these chunks may even take the form of long drawn-out strands, known as Pele's hair. Sometimes basalt aerates into reticulite, the lowest density rock type on earth. Although Hawaiian eruptions are
