Late Paleoproterozoic Metamorphic-Anatexis Events and Their Tectonic Implications in Longshoushan Area, Alxa Block

摘要: 阿拉善地块位于华北克拉通的西南缘，其早前寒武纪地质演化及构造归属存在争议，这严重制约了华北克拉通构造格局和演化的研究.龙首山杂岩为阿拉善地块少有的早前寒武纪变质基底，记录了古元古代多期变质事件，可为解决上述争议提供依据.以龙首山地区中部金川矿区内、龙首山杂岩中的花岗伟晶岩和黝帘斜长角闪岩为研究对象，系统开展岩相学、锆石和全岩的元素地球化学，以及锆石U-Pb年代学的研究.花岗伟晶岩的SiO2介于69.70%~73.08%，属于弱过铝质、钾玄岩的范畴，为混合岩化过程中地壳岩石低程度部分熔融的产物.在花岗伟晶岩中锆石核部获得了1 892±7 Ma(MSWD=0.76)的上交点年龄，代表花岗伟晶岩的形成年龄.黝帘斜长角闪岩的SiO2介于41.51%~48.92%，其原岩为拉斑玄武质的辉绿岩.黝帘斜长角闪岩中的锆石均为变质锆石，所获得的1 830±8 Ma(MSWD=0.61)加权平均年龄代表了一期角闪岩相变质事件的时间.结合前人的研究，龙首山地区在古元古代晚期存在强烈的变质/深熔事件，可能与碰撞造山事件有关.而通过构造热事件的对比，认为阿拉善地块与华北克拉通的孔兹岩带在早前寒武纪具有亲缘关系.Abstract: The Alxa block is located in the southwestern margin of the North China craton. The Early Precambrian tectonic evolution and tectonic affinity of the block remain unknown or controversial, which restricts the study of the tectonic framework and evolution of the North China craton. The Longshoushan complex is one of the few Early Precambrian metamorphic basement rocks in the Alxa block, and records multiple Paleoproterozoic metamorphic events. Hence, which makes it possible to solve the above problems. It presents petrography, whole-rock geochemistry, and mineralogy, mineral geochemistry and chronology of zircon for the granitic pegmatite and zoisite amphibolite in the Longshoushan complex from the Jinchuan mining area in the central part of the Longshoushan area. The granitic pegmatite is characterized by SiO2 contents of 69.70%-73.08%, belongs to weak peraluminous and shoshonite series, and formed from low degree partial melting of crustal rocks during migmatisation. The intersection ages of 1 892±7 Ma (MSWD=0.76) were obtained from the core of zircon in granitic pegmatite, representing the formation age of the granitic pegmatite. The zoisite amphibolite is characterized by SiO2 contents of 41.51%-48.92%, and is the metamorphic product of tholeiitic diabase. Zircons in the zoisite amphibolite are amphibolite facies metamorphic zircons. The weighted average age of 1 830±8 Ma (MSWD=0.61) represents an amphibolite facies metamorphic event in the Longshoushan area. Combined with previous studies, there was a strong metamorphic-anatexis event in the Late Paleoproterozoic in the Longshoushan area, which is most likely related to a collisional orogeny. Through the comparison of tectonic-thermal events, it suggests that the Alxa block and the Khondalite belt of the North China craton have affinity in the Early Precambrian.
