Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.
根据Ar-Ar热年代学研究,精确测定了早二叠世伸展变形和晚二叠世挤压变形的峰期时代分别为290Ma和259Ma.2、提出了关于哈尔里克山南麓小铺一带变质带和变质作用的新认识根据显微观察资料和特征变质矿物的出现,把小铺一带的变质岩由SW向NE方向依次划分为黑云母带、石榴石带、十字石带、红柱石带和矽线石带等变质带;初步确定该区的变质作用属于中温-低压型,变质作用发生的时代为290Ma左右,是该区早二叠世地壳伸展的产物。3、首次提出哈尔里克山南麓在石炭纪可能发育弧后盆地的新观点根据哈尔里克山南麓原&居里得能组&岩屑砂岩的碎屑锆石SHRIMP U-Pb定年,确认这套地层的沉积不早于晚泥盆世,很可能是石炭纪,而不是前人所说的前寒武纪;结合对其区域地质背景、源区位置和沉积环境分析,推测该区石炭纪可能为滞后弧后盆地和弧后隆起区构造背景。4、进一步证明哈尔里克山不发育与岛弧演化相关的泥盆纪岩浆活动根据对代表性闪长岩和花岗岩的锆石SHRIMP年代学研究获得的新资料,结合该区已有相关资料的综合研究,确定哈尔里克山岩浆岩分别形成于奥陶纪-志留纪和石炭纪晚期-二叠纪,不存在泥盆纪的岩浆岩,进而认为该区泥盆纪不属于岛弧环境。5、重建了哈尔里克山古生代以来的地质演化过程根据区域资料以及本次研究所获得的资料,把哈尔里克山古生代以来的构造演化划分中奥陶世-早志留世为岛弧、中志留世-晚泥盆世为弧后区、石炭纪弧后伸展、二叠纪为后碰撞伸展与挤压、中生代差异隆升和晚新生代陆内再造山过程等构造阶段。6、初步估算了哈尔里克山地壳缩短率和缩短量根据前中生代地层褶皱估算的哈尔里克山南山口-口门子、石城子-白石头和沁城-小铺三条剖面的地壳缩短率分别为16.2%、19.8%和20.1%,相应的地壳缩短量分别为4.3km、9km和11.3km。

Here I reported new structural data to answer above question, including field section observations and geologic map with large scale in a key area, accompanying with detail microstructural observations, quartz C-axial fabric analyses, and tectono-thermogeochronology (40Ar/39Ar and zircon SHRIMP U-Pb method). Taking available previous data into account, following progression is achieved:1. Completely rebuilding the post late-Paleozoic deformation history of the Harlik MountainFive stages of deformation were identified:(1)pre-Permian compression deformation which may have resulted from pre-Permian subduction;(2) earlier Permian post-collision extension;(3) middle Permian west-east directed dextral slip shearing;(4) later Permian nearly N-S compression deformation; and (5) later Cenozoic intra-plate N-S compressional deformation.

Since the ore-bearing rock is located in the area of the geological background, the model parameters varies from here to there due to the topography, soil and vegetation. The remotely sensed data recorded the various information of the ore-forming procedure at one time, so the ore-bearing rock information of the characteristic of weakness, not easy to detect, surface weathering and environmental interfering make it more difficult to unveiling.
