| 摘 要： | 贵州习水河坝矿区磷矿，产在上震旦统灯形峡阶中上部位，矿层厚．０．６５～１．８５ｍ，Ｐ２Ｏ５含量２０％～３１．８５％，是贵州境内新近发现的磷矿。岩矿石中富含藻类、古孢子及软舌螺化石，经研究认为磷矿磷质来源与生物有关，是水体生物－化学作用生成的磷矿床。分布在贵州习水、开阳、瓮安及都匀一带，是在本区寻找优质磷矿有远景、有希望的地区。

PHOSPHATE DEPOSIT IN XISHUIHE REGION,GUIZHOU : GEOLOGICAL CHARACTERISTICS AND GUIDE FOR ORE-HURTING |
| |
| Abstract: | Abstract A newly located phosphate resource, the phosphate deposit at the dam sector of Xishui river in Guizhou lies in the middle and upper parts of Late Sinian Dengyinxia stage, thickening 0. 65～1. 85 m and grading 20～31. 5% P2O5. The rocks and ores are crowded with so numerous fossils such as algae, palaeospore and hyokitha as there to be possibility for the phosphate materials to have been supplied by organism and hence for the deposit to have been originated by biochemical process in the water body. Promising areas for hurting Xishui deposit of its kind, furthermore highgrade, are bellyed to cover Xishui, Kaiyang, Wengan and Duyun |
