1New Apatite Fission-Track Ages of the Western Kuqa Depression:Implications for the Mesozoic–Cenozoic Tectonic Evolution of South Tianshan,Xinjiang显示文摘The Mesozoic–Cenozoic uplift history of South Tianshan has been reconstructed in many ways using thermochronological analyses for the rocks from the eastern Kuqa Depression. The main difference in the reconstructions concerns the existence and importance of Early Cretaceous and Paleogene tectonic activities, but the existence of a Cenozoic differential uplift in the Kuqa Depression remains enigmatic. Here, we present new apatite fission-track ages obtained for 12 sandstone samples from the well-exposed Early Triassic to Quaternary sequence of the Kapushaliang section in the western Kuqa Depression. The results reveal that there were four pulses of tectonic exhumation, which occurred during the Early Cretaceous(peak ages of 112 and 105 Ma), Late Cretaceous(peak age of 67 Ma), Paleocene–Eocene(peak ages at 60, 53, and 36 Ma), and early Oligocene to late Miocene(central ages spanning 30–11 Ma and peak ages of 23 and 14 Ma), respectively. A review of geochronological and geological evidence from both the western and eastern Kuqa Depression is shown as follows.(1) The major exhumation of South Tians Shan during the Early Cretaceous was possibly associated with docking of the Lhasa block with the southern margin of the Eurasian plate.(2) The Late Cretaceous uplift of the range occurred diachronically due to the far-field effects of the Kohistan-Dras Arc and Lhasa block accretion.(3) The Paleogene uplift in South Tianshan initially corresponded to the far-field effects of the India–Eurasia collision.(4) The rapid exhumation in late Cenozoic was driven by the continuous far-field effects of the collision between India and Eurasia plates. The apatite fission-track ages of 14–11 Ma suggest that late Cenozoic exhumation in the western Kuqa Depression prevailed during the middle to late Miocene, markedly later than the late Oligocene to early Miocene activity in the eastern segment. It can be hypothesized that a possible differential uplift in time occurred in the Kuqa Depression during the late Cenozoic.YANG Wei LI Jianfeng GUO Zhaojie Marc JOLIVET Gloria HEILBRONN 2017Acta Geologica Sinica(English Edition)2017,91,2:4
2Origin of the Oligocene Tuolangla porphyry-skarn Cu-W-Mo deposit in Lhasa terrane,southern Tibet显示文摘Although some porphyry-skarn deposits occur in post-collisional extensional settings,the post-collisional deposits remain poorly understood.Here the authors describe the igneous geology,and mineralization history of Tuolangla,a newly-discovered porphyry-skarn Cu-W-Mo deposit in southern Tibet that belongs to the post-collisional class.The deposit is associated with Lower Cretaceous Bima Formation.It was intruded by granodiorite porphyry intrusions at about 23.1 Ma.Field investigation indicated that mineralization is spatially and temporally associated with granodiorite porphyry.Molybdenite yielded a Re-Os weighted mean age of 23.5±0.3 Ma and is considered to represent the age of skarn mineralization at the deposit.Theδ^34S values of sulfides,concentrated in a range between 0.6‰to 3.4‰,show that the sulfur has a homogeneous source with characteristics of magmatic sulfur.The Pb isotopic compositions of sulfides indicate that ore-forming metal materials were derived from the mantle and ancient crust.The granodiorite porphyry displays high SiO2(68.78%–69.75%)and K2O(3.40%–3.56%)contents,and relatively lower Cr(2.4×10^-6–4.09×10^-6),Ni(2.79×10^-6–3.58×10^-6)contents,and positiveεHf(t)values(7.7–12.9)indicating that the mineralization porphyry was derived from the partial melting of juvenile lower crust.The Tuolangla deposit is located in the central part of Zedang terrane.This terrane was once considered an ancient terrane.This terrane is in tectonic contact with Cretaceous ophiolitic rocks to its south and Mesozoic continental margin arc volcanics and intrusions of the Gangdese batholith of the Lhasa terrane to its north.Thus,the authors proposed that the Oligocene porphyry skarn Cu-W-Mo mineralization is probably associated with the Zedang terrane.This finding may clarify why the Oligocene(about 23 Ma)deposits are found only in the Zedang area and why mineralization types of the Oligocene mineralization are considerably different from those of the Miocene(17–14 Ma)mineralization.Yong Huang Ming-hua Ren Wei Liang Guang-ming Li Kelly Heilbronn Zuo-wen Dai Yi-yun Wang Li Zhang 2020China Geology2020,3,3:3
3西南天山前陆盆地侏罗纪-白垩纪盆山格局——来自碎屑锆石年代学的证据显示文摘目前对天山地区,特别是天山南缘中生代盆山格局认识尚存分歧。本文着眼于侏罗纪-白垩纪这一盆山演化关键阶段,利用碎屑锆石LA-ICP-MS U-Pb定年法对西南天山前陆盆地康苏剖面中侏罗统杨叶组、下白垩统克孜勒苏群沉积开展物源分析。发现中侏罗统杨叶组碎屑锆石U-Pb年龄分布于369~2687 Ma间,基本分布在369~404 Ma(约占4%)、418~501 Ma(约占19%)和544~2687 Ma(约占77%)3个范围;下白垩统克孜勒苏群碎屑锆石U-Pb年龄分布于243~2820 Ma间,集中于253~414 Ma(约占35%)、423~489 Ma(约占27%)和668~2820 Ma(约占37%)3个范围。中侏罗统碎屑锆石年龄分布范围广,各年龄组分均较突显,反映中侏罗世西南天山前缘流域体系宽广,天山内各主要源区均得到沟通,物源范围广阔。下白垩统克孜勒苏群锆石年龄分布明显集中,反映早白垩世西南天山前缘源区范围有所缩小。西南天山前缘与库车前陆盆地的物源构成在中侏罗世存在一定差异,而在早白垩世呈现相似特征。包括西南天山前陆盆地在内的天山南缘或于早白垩世经历一期小规模构造反转,导致山-盆构造分异与抬升-剥蚀增强。杨威 郭召杰 姜振学 Gloria Heilbronn 张晨 王思维 2017大地构造与成矿学2017,41,3:3
