中文摘要: |
如下事实表明,黔东隆里-秦溪地区极有可能存在一颇具规模的优质金石原生矿:(1)金刚石及其伴生矿物、化探异常紧密共生;(2)业已查明在贵州境内存在三个金刚石补给源,直接补给湖南沅水干流的三个金刚石工业砂矿它们分别是:a.马坪金刚石原生矿;b.清水江、都柳江上游的早泥盆世古砂矿;c.隆里金刚石异常。然而前二者对沅水砂矿的贡献率几乎可以忽略不计,显然隆里金刚石异常是其重要补给源无疑;(3)成矿期古地面构造变形所导致的差异剥蚀表明,潜在矿体保存条件良好;(4)在秦溪-罗里间存在一“Google地球”影像异常,并与一伴生矿物异常相重叠,似乎并非巧合。因此,不应忽 视该区金刚石原生矿的找矿前景。 |

The reality shows there maybe a sizeable high quality primary diamond deposit in Longli-Qinxi area:(1)diamond is paragenetic wih its associated mineral and geochemical anomaly;(2)3 diamond recharge sources has been found which recharge 3 diamond placer of stem stream of Yuan river in Hunan directly:a.Maping primary diamond deposit,b.early Devonian ancient placer of upper Qingshuijiang and Duningjiang,c.Longli diamond anomaly.The function of the first two is small,obviously Longli anomaly is an important recharge source;(3)different erosion caused by paleo-surface structural deformation in the mineral stage shows the potential oreody kept well;(4)a ‘Google Earth’ imaging abnormality was found in Qinxi-Luoli area,and overlap with a associated mineral anomaly,it’s seemed not a coincidence.So the prospecting potential in this area should not be ignored. |
