A study of barium minerals from the Yukon Territory

University of British Columbia

A study of rare barium minerals from the Yukon Territory has resulted in the discovery of at least one and possibly five new species. The present investigation is concerned with one of these, a barium-calcium-iron-alumino-silicate, which is tentatively classed as an inosilicate and named keeleite. The optical and physical properties, a chemical analysis, and the calculation of its formula are presented. The mineral has also been successfully synthesized. An X-ray study of some supergene and alteration products present in the rocks revealed the presence of an interesting mixture of barium-calcium carbonate salts, similar to those obtained as laboratory products. A paragenesis Is also presented.
