摘要
In 1977, we gathered a skyblue to bluish mineral in the gabbro and gabbro-diorite country rock of 3? pegmafite, and our studies showed that it is holmquistite. It is brachyprismatic and acicular, its size 0.5×0.3×0.1mm or smaller, with strong glassy luster, white streak, Moh’s hardness 4—4.5, specific gravity 2.93±0.01 （by specific gravity bottle）.
