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。

For Southwestern Margin of Aqikekule Lake ophiolite, their field geological, petrological, minerological, petrochemical and geochemical characteristics show that:① it outcropped as tectonic slices along the near west-to-east strike Kunzhong fault and is composed of metamorphic perodotties, cumulates and volcanic rocks, in which, chromites are distributed in the upper part of metamorphic peridotites as pods, or in the lower part of cumulates as near-strata;② metamorphic peridotites include serpentinites, chromite-bearing serpentinites, chlorite-epidote schists and chromitites, of which, chromitites have nodular and orbicular structure, and cumulates include pyroxenits, serpentinites, chromite-bearing serpentinites, chromites and metamorphically mafic rocks and only basalts are seen in volcanic rocks;③ Cr# of chromites suggest that they formed in the SSZ and Al〓O〓 and TiO〓 of metamorphic peridotites also suggest SSZ environment;④ metamorphic peridotites have V type and enriched LREE patterns, cumulates have from strongly depleted LREE, flat REE to enriched LREE patterns with universally striking positive Eu anomalies and basalts show flat REE or slight enriched LREE patterns with no Eu anomalies;⑤ trace element and Sm-Nd isotope characteristics of metamorphic peridotites imply their strikingly heterogeneous mantle character ε〓(t+4.39～+26.20 and later Nb, Ta fertilization;⑥ trace element characteristics of basalts and their tectonic diagrams show they probably formed in the rifted island arc or back-arc basin environment.

对阿其克库勒湖西南缘蛇绿岩，野外地质、岩石学、矿物学、岩石化学以及地球化学等特征表明：①该蛇绿岩以近东西向、沿昆中断裂呈构造岩片出露，由变质橄榄岩、堆晶岩和火山岩三个单元组成，其中见铬铁岩呈豆荚状产于变质橄榄岩的上部，或呈似层状产于堆晶岩的下部；②变质橄榄岩包括蛇纹岩、含铬铁矿蛇纹岩、绿帘绿泥片岩和铬铁岩等类型，其中，豆荚状铬铁矿具有结核状构造和球状构造，堆晶岩包括辉石岩、蛇纹岩、含铬铁矿蛇纹岩、铬铁岩和变质基性岩等类型，火山岩仅见玄武岩；③铬铁矿的Cr#表明其形成在俯冲带，变质橄榄岩的Al〓O〓和TiO〓成分也指示了SSZ环境；④变质橄榄岩的稀土配分型式见V型和LREE富集型两种型式，堆晶岩表现出从LREE强烈亏损、REE平坦分布到LREE富集的配分特征，并且普遍具有醒目的正Eu异常，玄武岩的稀土配分型式表现为平坦型或LREE略富集，无Eu异常；⑤变质橄榄岩的微量元素及Sm-Nd同位素特征指示了其地幔的显著不均一性ε〓(t为+4.39～+26.20以及Nb、Ta在后期的富集；⑥玄武岩的微量元素特征及构造图解表明其可能形成在裂谷岛弧或不成熟的弧后盆地环境。
