摘要
胶东金矿集中区是我国最大的黄金生产基地。上世纪末,70%以上的金矿山资源严重枯竭,社会隐患突出。鉴于浅部矿多已被勘查开发,深部找矿成为缓解资源危机的当务之急。胶东中生代岩浆热液交代蚀变与金的成矿作用密切相关,成为深部外围找矿的重要标志。然而,区域构造蚀变岩带与成矿规律的研究非常薄弱,需要加强。在导师吴淦国教授的指导下,本人选择《胶东金矿区域构造蚀变岩带地质特征与流体成矿规律研究》作为学位论文的选题。
     作者本科期间开始参加胶东金矿的科研项目,硕士期间又参加自然科学基金项目“胶西北金矿流体地质地球化学与构造成矿研究”,以及山东黄金科研项目“玲珑矿田东山矿床九曲东段的比例尺成矿定位预测”和“玲珑矿田东山矿床九曲东段的比例尺成矿定位预测”等科研课题。针对选题,经过大量的野外和井下地质观测,系统的室内研究和测试分析,取得了大量的第一手资料。在研读国内外相关文献和综合分析总结前人研究成果的基础上,按时完成了硕士学位论文,取得了以下主要进展:
     1、探索编制了中生代侵入岩分布概图,首次将胶西北的滦家河、毕郭和郭家店等岩体归为滦家河-伟德山型花岗岩岩石单元,并认为它们与含金热液成矿的关系最直接。
     2、胶东西部断裂蚀变带钾化阶段的应变比值大于胶东东部,而绢英岩化阶段构造应变强度西部低于东部。构造应变分析说明钾长石化期间构造应力方向来自西部,可能与郯庐断裂构造的挤压有关;黄铁绢英岩化阶段压力来自东部,作者认为与滦家河-伟德山型花岗岩侵入隆起有关。
     3、计算胶东断裂蚀变带的构造附加静水压力值,显示该值西部高于东部,为郯庐断裂是主要区域流体驱动力的认识,提出了定量化证据。
     4、胶东成矿流体数据显示,钾化带的均一温度自西向东明显升高,而绢英岩带的均一温度西低东高。蚀变岩带流体温度与其应变比值相反的区域性变化趋势,显示西部属于相对高压低温的环境,而东部为相对低压高温成矿流体环境。
     5、胶东地区具有从郯庐断裂由西向东,金矿床类型逐渐由蚀变岩型金矿床向石英脉型金矿床过渡,金矿规模由大变小等区域分布规律。本研究通过蚀变岩规模类型结合流体性质的变化揭示了区域流体成矿的机理,由此认识到胶东具备西部发育规模较大的蚀变岩型金矿,而东部形成规模较小的石英脉型金矿的地质构造环境。
The Jiaodong gold concentrated mineralization zone is the largest gold productionbase in China. Last century,over70percent of gold mines in Jiaodong Peninsula haveserious situation that their golden resources is exhaustion, and there also have someSocial hidden trouble because of this situation. Considering that the shallow gold hasbeen exploration and development, the most important thing is finding a way of deepperipheral forecasting to solve resource crisis. In Jiaodong, Mesozoic magmatichydrothermal alteration has a very close relationship with the gold mineralization, andit is also an important symbol of deep prospection. However, the research of regionalrock band which has been impacted by structure and altered Mesozoic magmatichydrothermal is very weak and it really needs to be enhanced. Because of theguidance from my academic advisor, Dr. WuGanguo, I choose the title of my masterthesis as “The study of geologic characteristics of regional tectonic altered rock beltand regulation of metallogenic fluid in Jiaodong Peninsula”
     When I was an undergraduate student, I had participated a research program inJiaodong. As a graduate student, I have participated National Science FoundationProject “Fluidic geochemistry and tectonic metallogenesis research of gold deposit inNorthwest of Jiongdong Peninsula”, Shandong gold research projects “Scalemetallogenic prediction positioning east area of Jiuqu in Dongshan mine in Linglong”.To write this thesis and get some first hand information, I have done numerous offield work, underground observation, and systematic indoor research and testinganalysis. On the base of reading lots of domestic and overseas related articles, I havefinished my Master thesis on time, and gotten some achievements:
     1. First time group the granite rock mass in Luanjiahe, Biguo and Guojiadian intoLuanjiahe-Weideshan granite unit, and try formation the distribution map of Mesozoicintrusive rocks. This granite unit also is considered that has the closest relationshipwith the hydrothermal solution which contain gold mineralization element.
     2. The strain ratio of Potassium stage in the fracture alteration zone in west ofJiaodong is larger than the east, but the strain ratio of Sericitization stage in thefracture alteration zone in west of Jiaodong is smaller than the east. The structuralanalysis shows the reason should be the pressure came from Tan-Lu fault zone; andthe pressure which impacted the strain ratio of Sericitization stage should be causedby Luanjiahe-Weideshan granite unit invasion.
     3. Calculation tectonic additional hydrostatic pressure of tectonic altered rock belt,and the conclusion shows that the pressure in west of Jiaodong is higher than the east.This conclusion provides quantitative evidence for the inference which thinks theTan-Lu fault zone is the source of driving force for the ore-forming fluid.
     4. The data of Ore forming fluid shows that the homogenization temperature ofPotassium stage in the fracture alteration zone in west of Jiaodong is higher than theeast; and the homogenization temperature of Sericitization stage in the west ofJiaodong is lower than the east. This variation tendency is opposite with the strainratio, and it shows that the metallogenic environment in the west of Jiaodong is Highpressure but low temperature, and the east is low pressure but high temperature.
     5. From west to east in Jiaodong, the gold deposits from the altered rock type to thequartz vein type, and the mines’ scale also are getting smaller. The research in thisthesis use the method of combines the characteristics of alterated rocks with fluidproperties to show the principle of ore-forming fluid mineralization. And through thisprinciple, the thesis finds the reason of larger altered rock type of gold mines are inthe west of Jiaodong area, but smaller quartz vein type in the east.
