The Late Carboniferous–Early Permian Ocean-Continent Transition in the West Junggar,Central Asian Orogenic Belt: Constraints from Columnar Jointed Rhyolite

引用

Acta Geologica Sinica(English Edition) 2019年第2期93卷 265-282页

作者： XU Shenglin CHEN Xuanhua LI Tingdong SHI Jianjie ding weicui LI Bing HUANG Penghui ZHANG Yiping ZHANG Yaoyao MA Feizhou School of Earth Sciences and Resources China University of Geosciences Chinese Academy of Geological Sciences Beijing Research Institute of Geological Engineering Design

The West Junggar of the western Central Asian Orogenic Belt is one of the typical regions in the term of ocean subduction, contraction and continental growth in the Late Paleozoic. However, it is still controversial on the exact time of ocean-continent transition so far. This study investigates rhyolites with columnar joint in the West Junggar for the first *** on zircon U-Pb dating, we determined that the ages of the newly-discovered rhyolites are between 303.6 and 294.5 Ma, belonging to Late Carboniferous–Early Permian, which is the oldest rhyolite with columnar joint preserved in the world at present. Geochemical results show that the characteristics of the major element compositions include a high content of SiO_2(75.78–79.20 wt%) and a moderate content of Al_2O_3(12.21–13.19 wt%). The total alkali content(K_2O +Na_2O) is 6.14–8.05 wt%, among which K_2O is 2.09–4.72 wt% and the rate of K_2O/Na_2O is 0.38–3.05. Over-based minerals such as Ne, Lc, and Ac do not appear. The contents of TiO_2(0.09–0.24 wt%), CaO(0.15–0.99 wt%) and MgO(0.06–0.18 wt%) are low. A/CNK=0.91–1.68, A/NK=1.06–1.76, and as such, these are associated with the quasi-aluminum-weak peraluminous high potassium calc-alkaline and some calc-alkaline magma series. These rhyolites show a significant negative Eu anomaly with relative enrichment of LREE and LILE(Rb, Ba, Th, U, K) and depletion of Sr, HREE and HFSE(Nb, Ta, Ti, P). These rhyolites also have the characteristics of an A2-type granite, similar to the Miaoergou batholith,which indicates they both were affected by post-orogenic extension. Combining petrological, zircon U-Pb dating and geochemical characteristics of the rhyolites, we conclude that the specific time of ocean-continent transition of the West Junggar is the Late Carboniferous–Early Permian.

构造高差分析是构造解析及平衡剖面制作与恢复的基础。长期以来,构造高差并没有一个严格的定义,也缺乏原理性描述;构造高差分析也主要局限在构造地貌和地形高差的分析。本文在分析前人有关构造解析、地貌高差和构造高差研究的基础上,提出构造高程概念,将构造高差定义为构造高程之差,拓展了构造高差的内涵;并将构造高程定义为地质点所在构造形成时的有效深度,通常用相对高程的负值来表示。提出构造高差分析的基本理念,将构造高差的本质理解为构造势能,赋予其时间和空间涵义。由此给出了构造高差的估算方法,以及不同构造环境下构造高程的厘定与构造高差的分析原则,探讨了构造高差的形成与地质作用过程之间的关系。本文提出的构造高差理论拓展了传统构造地质学关于构造高差的认识,为构造高差分析在地球科学研究中的拓展应用给出了理论基础。

我国新疆西北部西准噶尔走滑断裂构造体系(简称"西准系")是中亚造山带巴尔喀什马蹄形构造的向东延伸部分,由于中生代成吉思-准噶尔断裂的右行走滑断裂作用而被分成了两个部分。西准系是一个多米诺式的走滑断裂构造体系,主要由达拉布特断裂、玛依勒断裂、巴尔鲁克断裂等三条NE走向的左行走滑断裂及其夹在它们之间的地块所组成,可能是晚古生代与走滑断裂相关的陆条弯曲(褶皱)作用的产物。同时,西准噶尔地区也是重要的晚古生代成矿带,产出有一些大型和超大型的金属矿床,包括包古图斑岩铜矿、哈图金矿、萨尔托海铬铁矿和杨庄铍矿床等。本文分析了西准系走滑断裂构造与元素分布之间的关系。结果显示,西准噶尔成矿带元素与地球化学块体以及铜、金、钼、铬铁矿等矿床的分布,均受晚古生代西准系的形成与演化过程的控制。其中,庙尔沟、红山岩体与金地球化学块体之间的反对称分布特征,说明了花岗岩类侵入体和金元素在达拉布特断裂左行走滑过程中发生了重要的物质调整与迁移作用。庙尔沟岩体的逆时针旋转运动,造成了环状断裂与裂隙系统,以及与之相对应的Cu、Pb等元素风火轮式的分布形式。走滑断裂作用与岩体旋转运动的共同结果,导致了金元素沿断裂和裂隙的迁移与成矿,使得西准地区金矿床在断裂和裂隙中的发育。断裂构造体系与元素地球化学异常之间的关系,可以用来有效指导西准地区未来矿产资源的勘查。
