| 摘 要： | 独山玉矿体赋存于加里东期的辉长岩体中,矿体一般规模较小,属于分布不均匀却又成群出现的小脉状矿体。通过对独山玉矿物成分的分析,认为矿物成分决定了玉石的颜色,玉石中TiO2、Cr2O3等微量元素的含量与玉石颜色相关。在分析独山玉矿地质特征、玉石成分、结构构造特征、矿床成因、找矿标志的基础上,认为独山玉矿资源潜力较大,指出了季河-大盆窑基性岩带中众多的隐伏基性岩体是独山玉的成矿远景区,是独山玉矿的重点找矿方向。

| Abstract: | Hosted in Caledonian gabbro body, Dushan jade orebody of small scales belongs to veinlet orebody in uneven distribution. According to the analysis on mineral composition of Dushan jade, we found that the jade colors are decided by the mineral composition, such as the content of some microelements TiO2 and Cr2O3. After analysing on the basis of geological, texture and structure characters, composition, deposit origin and prospecting criteria of Dushan jade, some conclusion had been got in this paper that most buried basic rock bodies in Ji river-Dapenyao basic rock belt are the metallogenic prospective area and the key prospecting directions for Dushan jade. |
