Possible definitions for dacite

barite
Most common barium mineral, barium sulfate (BaSO4). It commonly forms as platy crystals (known as crested barite). Barite is abundant in parts of Spain, Germany, and the U.S. Commercially, ground barite is used in oil well and gas well drilling muds; in the preparation of barium compounds; as a filler for paper, cloth, and phonograph records; as a white pigment; and as an inert material in colored paints.


dace
Any of various small, slim, active freshwater fishes of the carp family (Cyprinidae). In England and Europe, the dace (Leuciscus leuciscus), a relative of the European chub, inhabits streams and rivers. It is a small-headed, silvery fish that grows to 10-12 in. (25-30 cm) long and weighs 1-1.5 lbs (0.5-0.7 kg). It lives in schools and eats plant and animal material. It is a good bait and sport fish but is not highly valued as food. In N. America, the name is applied to various small cyprinids found in creeks and bogs, mostly in the central and S U.S.


Dacia
Ancient country, central Europe. Roughly equivalent to modern Romania, the area's earliest known inhabitants were Getae and Dacian people of Thracian stock. Known for its rich silver, iron, and gold mines, the region was made a Roman province in AD 107 after two centuries of hostilities. It was abandoned to the Goths in 270 and ultimately divided into the principalities of Walachia and Moldavia.


dunite
Yellowish green to green igneous rock composed almost entirely of olivine. Chromite and magnetite also occur in dunite, as do spinel, ilmenite, pyrrhotite, and platinum in some cases. Dunites may be a source of chromium. Places of occurrence include Dun Mtn., New Zealand (the source of its name), S. Africa, and Sweden.


halite
Naturally occurring sodium chloride (NaCl), common or rock salt. Halite occurs on all continents, in beds that range from a few feet to more than 1,000 ft (300 m) in thickness. Termed evaporite deposits because they formed by the evaporation of saline water in partially enclosed basins, they characteristically are associated with beds of limestone, dolomite, and shale. Halite is found in large deposits in New York and in Russia, France, India, and Canada.


latite
Type of igneous rock that is abundant in W N. America. Usually white, yellowish, pinkish, or gray, it is the volcanic equivalent of monzonite. Latites contain plagioclase feldspar (andesine or oligoclase) as large, single crystals (phenocrysts) in a fine-grained matrix of orthoclase feldspar and augite.


Lucite
Trademark names of the organic compound polymethyl methacrylate, a synthetic polymer of methyl methacrylate. Colorless and highly transparent, it has high dimensional stability and good resistance to weathering and shock. It is used in aircraft canopies and windows, boat windshields, and the like. An object made of Lucite has the unusual property of keeping a beam of ...
