A Study Of Ore-forming And Ore-controlling Structures In The Jiaojia Gold Deposit Of Shandong Province

The Jiaojia gold field is located in the northwestern of Jiaodong area, tectonicallybelongs to the Cathaysian second uplift with glue north uplift. Multistage mantle plumeevolution of tectonic units in the Guo store mantle branch west side of the peripheraldetachment zone. Jiaojia gold deposit is one of the last three decades an importantprospecting achievements for our broken with altered rock type gold, and achieved fruitfulresults of the prospecting, research results can be described as "voluminous".Take full advantage of previous data on the basis of field studies progress, startingfrom the regional tectonic and seismic characteristics, geological features, geochemistry,and ore-controlling structures, mineralization study from the mantle plume evolution viewJiaojia gold Tin ore-controlling structure conditions, analysis of mantle branchore-controlling characteristics, the establishment of the ore-controlling mode of Jiaojiagold field. Initial speculation prospecting direction. Main understanding of:1、Combined with regional geological features to study the geophysical characteristicsof that: exquisite hybrid rock along the NNE of a low angle thrust fault penetration, thespatial geometry of the rock in south-central to the south and thin thick North wedge, andhas characteristics repeatedly activities.2、Tectonic units of the2mantle plume evolution in multi-level the Guo store mantlebranch is the main ore-controlling structures, the peripheral detachment with developmentof a series of ductile-brittle shear structure to control Jiaojia gold field output features ofthe deposit.3. The Jiaojia Matang, hope children Mountain Temple Zhuang and other golddeposits, as well as in recent years proven the deep gold deposits-Jisho deep Ministrygold deposit, Matang deep Ministry gold deposit, coke home deep Ministry gold deposit,low grade ore body can linking inter-linkages between the various ore bodies, is not anisolated, deep, shallow gold is actually the case with a gold deposit, and can be integratedto Jiaojia gold field mode..4、Yanshan Movement glue Northwest mineralization concentrated into the stage ofthe evolution of mantle branch of the Laiyang-Lacey mantle sub-plume and its peripheralGuo store Qishan Panshi stores, etc., and the formation of the corresponding series (whichcan have a certain equally spaced) NE-trending secondary detachment detachment zoneand the NW to the horizontal sheets of fracture. Large-scale magmatic activity in the deeprole of ductile shear zone axis, and rock in the invasive process of the exquisitely complexbody, rise late ore hydrothermal along the new fissure metasomatism role, and activationtransfer part of the early gold, along the related tectonic weak zone penetration andaggregation of mineralization.5、 Jiaojia gold field deep good exploration potential, Ⅰ, the main ore body, alongthe main tectonic belt slows, and extends along the tendency III orebody at the change ofthe tendency of the main structural interval will still appear.
