| 摘 要： | 在对莱芜接触交代铁矿地质特征研究中发现以往地质报告在矿体连接上存在混乱,使矿体形态失真。为便于今后矿体对比和成矿规律的认识,提出了矿体形态分类原则,并以三分法对矿体形态进行分类。指出矿体产状变化是矿体膨胀收缩、分支复合和尖灭再现的结果。根据矿体形态分类指出了找矿方向。不同的矿体形态反映不同的控矿构造,反映不同的矿体规模,反映不同的成矿岩体形态产状。单斜缓倾矿体的成矿岩体是岩床,控矿较小;陡倾矿体和背向斜矿体的成矿岩体是岩盖,控矿较大。

| Abstract: | During the study on geological characteristics of Laiwu contact geothermal metasomatic iron deposit,it is found that the information of ore bodies contaction o given in the former report is in messy,which caused distortion of ore body shape.In order to contrast ore bodies and recognize mineralization rule,classification principle of ore bodies are put forward,and the ore bodies are classified by using trichotomy method.The change of ore occurrence is the result of ore expansion and contraction,and branch recombination and thinning out.According to morphological classification,ore prospecting directions are pointed out.Different ore bodies reflect different ore-controlling structures,different ore body sizes,and different rock ore occurrences.Monocline dipping ore body mass is the bedrock mineralization,and ore-controlling scale is small.Ore-forming rock of steep inclined ore bodies is rock cover,and ore-controlling scale is large. |
