轰矿是分布在北海道西南部草原地区的低温热液金银脉状矿床之一,矿床以大量方解石,锰矿物或伴随少量的以铜、铅、锌硫化物为特征.其开发历史较久,从1897年至1943年封坑前出矿约100万吨(品位Au10g/T,Ag300g/T).其后,1963年到最近曾进行小规模出矿和探矿,但现在已封坑.在本报告中,研究轰矿床主要矿脉忠越 Heshun Mine is one of the low-temperature hydrothermal gold-silver vein deposits located in the grassland of southwestern Hokkaido. The deposit is characterized by a large amount of calcite, manganese ore or a small amount of copper, lead and zinc sulfide, and has a long history of development. Approximately one million tons of ore (grade Au10g / T, Ag300g / T) were mined before the pit closure from 1897 to 1943. Later, small-scale mines and prospecting were carried out recently until 1963, In the report, we studied the loyalty and loyalty of the major mineralized ore deposits
