菱镁钙钡石(Benstonite)是少见的碳酸盐矿物。原发现于美国阿肯色州温泉区的重晶石坑道中,为很小的析出物,具有清楚的菱面解理,与石英、重晶石及方解石伴生。1972年,笔者在西北某地收集碳酸盐矿物标本中,发现该矿物。近年来,对该矿物做了一定的测试研究工作。经中国矿物岩石地球化学学会确定为Benstonite。矿物译名,根据其主要 Benstonite is a rare carbonate mineral. Originally found in barite tunnels in the hot springs area of ​​Arkansas, USA, it is a small precipitate with clear rhombohedral cleavage associated with quartz, barite and calcite. In 1972, the author collected carbonated mineral specimens somewhere in the northwest and discovered the mineral. In recent years, the mineral has done some testing and research work. The Chinese Society of Mineralogy of Petrology identified as Benstonite. Mineral name translation, according to its main
