摘要
在对辽宁砖庙矿区硼矿床的矿物学研究中发现了硬石膏。该矿物产于硼矿体中,与遂安石、菱镁矿、镁橄榄石、袁复礼石、硼铝镁石等共生。通过矿物学研究和稀土元素、硫同位素的分析表明,由于硬石膏是蒸发沉积变质成因的。
Anhydrite was discovered in boron deposits of Zhuanmiao area, Liaoning Province. It is hosted in boron ore body, and is coexisted with suanite, magnesite, forsterite, yuanfuliite and sinhalite etc. The analysis results of REE and sulfur isotope for anhydrite show that it was formed within an original evaporated environment in marine. Therefore, we think that boron deposits was formed in the environment of evaporation sedimentation metamorphism.
