| 中文摘要: |
| 在宜昌磷矿杉树垭磷矿区新一轮地质勘探工作中,在原主要工业矿层之下新发现了一工业磷矿层,命名为中磷层一矿层(Ph21).Ph21矿层受NW向古构造控制,其厚度、品位的变化具有明显的分区性和方向性,即呈NW-SE向展布,从杉树垭矿区东部矿段向北,其厚度、品位均呈增加趋势.新工业磷矿层的发现不仅具有巨大的经济价值,而且对宜昌磷矿北部地区找矿具有重要意义. |
| 英文摘要: |
| In prospecting for Shashuya diggings,Yichang phosphorite mine,a new industrial ledge of phosphorite(Ph21) have been found below the originally major industrrial ledge.Ph21 ledge is controlled by palaeo-structure and the thickness and grade change in NW-SE direction.From the east Shashuya ore domain to north the new ledge appears to increase in thickness and grade.Finding of the new industrial ledge have not only the great economy value,but also important guidance for the P ore-searching in north of Yichang phosphoritemine. |
