| 中文摘要: |
| 瓮福磷矿英坪矿段的B矿层不同类型磷块岩具有明显变化规律,由上往下显示为:白云质磷块岩—致密状磷块岩—含砂(砾)团块状磷岩—砂砾状磷块岩(具典型的条带状构造)—(含团块)砂砾状磷块岩—砂砾或团块状磷块岩。通过系统分析含矿岩系各矿石类型纵、横分布特征,发现B矿层含有典型的条带状沉积构造,它选择性集中分布,沿条带状构造磷块岩分布区,矿层整体厚度较大。分析表明,在其展布方向的NE处,可能为今后该区磷块岩深部找矿勘探的有利地段。 |
| 英文摘要: |
| The different types of phosphate rock in the B layer phosphate ore has obvious change rule, it is from the top-down:the dolomitic phosphate rock-compact phosphate rock-sand (gravel) lump phosphate rock-sand and gravel phosphate rock(it has the typical banded structure)-(lump)grit phosphate rock-sand and(or)gravel phosphate rock or lump phosphate.Through the systematic analysis of the longitudinal and lateral distribution chaaracteristics of various types of the phosphate ore deposits in ore-bearing,we found that the B layer phosphate ore contains typical banded sedimentary structure, and it’s selectively concentrated distribution.The ore bed thickness more larger along the banded structure of phosphate rock in area.Analysis It is analysis show that along the banded structure distribution direction of NE,it may be a favorable ore-prospecting location for further exploration of deep phosphate rock in this area. |
