矽卡岩在我国有广泛分布,并形成鉄、銅等許多有价值的金屬矿床,但截至目前为止,其中尚未見有合褐帘石的。最近,我们根据河北地质勘探公司順便检查队自翼西南某矽卡岩鉄矿区采来的标本进行研究,发现透辉石矽卡岩中有不少褐帘石(在标本中含量可达30％以上)。因而岩石定名应改为“褐帘石透辉石矽卡岩”。在野外肉眼鉴定时,誤將褐帘石当作綠帘石或阳起石了。現在將我們初步研究结果报导于下,供有关同志們参考,特别希望在矽卡岩分布地区工作同志注意此种褐帘石的发现。褐帘石的产狀:这种褐帘石透輝石矽卡岩产于接 Skarn is widely distributed in our country, and formed a lot of valuable metal deposits such as copper, copper and so on, but up to now, there has not been any co-curtain stone. Recently, according to a survey by Hebei Geological Prospecting Company, a team from a skarn mining area southwest of the skull mining specimens were found in diopside skarn there are a lot of brown curtain stone (in the specimen content of up to 30% the above). Therefore, the name of the rock should be changed to “brown curtain diopside skarn.” When the naked eye in the wild identification, the mistaken brown curtain stone as eclogite or actinolite. We will now report the results of our preliminary study for the reference of the relevant comrades. In particular, we hope that comrades working in skarn areas will pay attention to the discovery of such brown curtain stone. The appearance of brown curtain stone: This brown curtain stone diopside skarn produced in the access
