Possible definitions for abadite
apatite
A member of the phosphate group of minerals, the world's major source of phosphorus, found as variously colored, glassy crystals, masses, or nodules. Much of it has a chemical composition approximating Ca5(PO4)3(F,Cl,OH). If not for its softness, apatite would be a popular gemstone; some of the material found is clear, but it is fragile and difficult to cut and polish.
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.
