| 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. |
