摘要
矿床产于大义山复式花岗岩体与中、上石炭统壶天群白云岩的接触部位,成矿母岩为大义山复式岩体中各种不同时代、不同岩性花岗岩,控矿构造环境是屏弊条件下的局部开放环境,方解石岩是硼矿床的侍征含矿岩石,含高镁质的围岩可以生成大量钙镁质矽卡岩,矽卡岩的产状特征有矿床学意义。
The boron deposit is located along the contact zone between Dayishan composite granite body and dolomite of Hutian Group of the Middle to Upper Carboniferous. Mineralizing Parent rocks are different times and lithologic-varying granites- Ore-controlling structural settings is recognized as opening setting in some areas under the condition of the restriction- Calcitite is a characteristic host rock of boron deposit. High magnesian country rock can be converted voluminously into Ca-Mg-skarn. The occurrence of skarn is of met allogenic significance.
