Possible definitions for eurite

augite
Most common pyroxene mineral, occurring chiefly as blocky crystals in basalts, gabbros, andesites, and various other dark igneous rocks. It also is a common constituent of lunar basalts and meteorites and may be found in certain metamorphic rocks, such as pyroxenites. Because the diopside-hedenbergite series and augite are nearly indistinguishable, the term augite is sometimes used to designate any dark green to black pyroxene with monoclinic symmetry (three unequal crystallographic axes with one oblique intersection).


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.


Curie
Polish-born French physical chemist. Born in Warsaw, she studied at the Sorbonne (from 1891). Seeking for radioactivity, recently discovered by H. Becquerel in uranium, in other matter, she found it in thorium. In 1895 she married fellow physicist Pierre Curie (1859-1906). Together they discovered the elements polonium and radium, and they distinguished alpha, beta, and gamma radiation. For their work on radioactivity (a term she coined), the Curies shared a 1903 Nobel Prize with Becquerel. After Pierre's death, Marie was appointed to his professorship and became the first woman to teach at the Sorbonne. In 1911 she won a Nobel Prize for discovering polonium and isolating pure radium, becoming the first person to win two Nobel Prizes. She died of leukemia caused by her long exposure to radioactivity. In 1995 she became the first woman whose own achievements earned her the honor of having her ashes enshrined in the Pantheon in Paris. See also F. and I. Joliot-Curie.


Curitiba
City (metro. area pop., 1995 est.: 2,270,000), capital of Paraná state, S Brazil. It lies about 3,050 ft (930 m) above sea level in the Brazilian Highlands near the headwaters of the Iguazú River. Founded in 1654 as a gold-mining camp, it became the state capital in 1854. From the early 19th cent. it received many European settlers, and immigration continued during the 20th cent. with the arrival of Syrians and Japanese. It is a modern commercial center. Its cathedral (1894) was inspired by that of Barcelona.


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.
