摘要:
为弄清金山店铁矿东区膨胀岩形成机理,分别用X射线衍射仪、扫描电镜和电子能谱仪检测和鉴定膨胀岩中膨胀矿物的种类、含量及膨胀岩的原岩. 检测和鉴定结果表明,膨胀物主要是蒙脱石,其次为伊利石和高岭石,膨胀岩的原岩为石英闪长岩. 在此基础上,对东区工程地质特征、膨胀岩形成的物质基础和动力条件进行了系统分析,揭示出膨胀岩体的低温热液蚀变、强膨胀岩体的地质构造、近矿强膨胀岩的热力接触变质等3种膨胀岩的形成机理,并提出了下盘膨胀岩分布具有条带性、大理岩层缺失部位即为膨胀岩、膨胀岩的膨胀性与岩体的破裂程度呈正比的发育规律. 根据研究成果,预测膨胀岩主要分布在34-40勘探线间,中间厚度在90 m左右,具有两端薄中间厚的特点.
Abstract:
To investigate the formation mechanism of the expansive rock at the east part of Jin Shandian iron mine,the types and their contents of the expandable mineral, the original rock in the expansive rocks were measured by using X-ray diffraction, scanning electron microscope and electron spectrometer. The test results show that the expandable minerals are mainly montmorillonite, followed by illite and kaolinite, and the original rock of the swelling rocks is quartz diorite. The engineering geological characteristics, the formation mechanism and the dynamic conditions of the expansive rock at east area were analyzed systematically. Three formation mechanisms: the low temperature hydrothermal alteration of expansive rock, the geological structure of strong expansive rock and thermal contact metamorphism of strong expansive rock near the mineral were suggested. The growth patterns of the expansive rock including the stripped distribution at the footwall, and the missing part of the marble stratum corresponding to expansive rock, and directly proportional relationship between the expansibility and the degree of fracture were also revealed. It is predicted that the expansive rock is mainly located in the 34-40 exploration line, with a distribution of the thickest part of 90 m in the middle, and thinnest part at the two ends.
