| 中文摘要: |
| 研究表明,满克头鄂博组、玛尼吐组、白音高老组和义县组中酸性火山岩是赤峰地区珍珠岩、沸石、膨润土、叶腊石、高岭石等非金属矿床的重要赋矿层位,并形成珍珠岩-沸石-膨润土成矿系列和叶腊石-高岭石成矿系列。在矿床特征和成因研究后认为,矿床的时空分布主要受控于区域性NNE向断裂和中生代火山岩建造,成矿作用对矿床成因类型及组合关系、成矿原岩对矿床地质特征、成矿微环境对矿床的改造均具有重要的控制作用;根据含矿建造、区域构造和矿床的分布特征,在区内划分出呈NNE-NE向展布的赛罕塔拉-查干诺尔、桥头-小牛群、宁城-平泉3条珍珠岩-沸石-膨润土成矿带和查干沐伦-哈拉哈达-罕苏木苏木叶腊石-高岭石成矿带,建立了赤峰地区珍珠岩-沸石-膨润土成矿系列及叶腊石-高岭石成矿系列的成因模式。 |
| 英文摘要: |
| The research shows that the perlite,zeolite,bentonite,pyrophyllite and kaolinite deposits occur mainly in intermediate-acid volcanic rocks of the Manketouebo formation,Manitu formation,Baiyingaolao formation and Yixian formation in Chifeng area as the perlite-zeolite-bentonite and the pyrophyllite-kaolinite deposit series.The research on origin and characteristics of the deposits reveals that the deposits are controlled by NNE regional fault and Mesozoic volcanic formation temporally and spatially.Genetic type and association of the deposits are controlled by the ore-forming processes,geological characteristics by the host rocks,rework by the micro-environments.According to the distribution of ore-bearing formation,regional fault and deposits,Shaihantala-Chagannuoer,Qiaotou-Xiaoniuqun and Ningcheng-Pingquan,the three perlite-zeolite-bentonite ore belts and the Chaganmulun-Halahada-Hansumusumu pyrophyllite-kaolinite ore belt are delineated and the genetic models of perlite-zeolite-bentonite and pyrophyllite-kaolinite deposit series are established in Chifeng area. |
