发现于四川农乐的钾锶矾,晶体发育完好,(000)解理完整,属于三方晶系,空间群R3m,一轴晶,负光性,Ne=1.549±0.001,No=1.572±0.001。钾锶矾在盐矿床中是后生矿物,其出现可以作为寻找可溶性钾盐矿床的标志。
The potassium-strontium alum found in Sichuan Nongle is well-developed and has complete cleavage (000). It belongs to the trigonal system with space group R3m, uniaxial crystal and negative light. Ne = 1.549 ± 0.001 and No = 1.572 ± 0.001. Potassium strontium alum is a meta-mineral in the salt deposit, and its appearance can be used as a marker for finding soluble potassium salt deposits.
