塔里木盆地东北缘库鲁克塔格地区新元古代构造-沉积演化
|
摘要
塔里木盆地库鲁克塔格地区保存了完整的新元古代南华纪—震旦纪地层,具有从早南华世火山岩-碎屑岩沉积,到晚南华世—早震旦世碎屑沉积,再到晚震旦世碎屑岩-碳酸盐岩沉积的演化过程。其中发育贝义西期、阿勒通沟期、特瑞艾肯期、汉格尔乔克期4期冰川沉积以及贝义西期、阿勒通沟期、扎摩克提期、水泉期4期火山作用。新元古代库鲁克塔格地区为大陆边缘裂谷,早南华世为强烈拉张断陷阶段,晚南华世—早震旦世为断陷向坳陷转变阶段,晚震旦世为稳定沉降阶段。以兴地断裂为界,南北两区具有不同的构造-沉积演化特征,早南华世南区为火山岩喷发中心,形成火山岩高地,北区为裂谷沉积中心,发育滨岸-陆棚沉积体系,整体具有南高北低的构造格局。晚南华世—早震旦世继承早南华世构造格局,南区以三角洲沉积为主,北区发育陆棚沉积体系。晚震旦世,南北两区沉积差异减弱,南区发育碳酸盐岩台地,北区为碎屑岩与碳酸盐岩混积陆棚。晚南华世—震旦纪南区结束火山活动,而北区发育多期次的火山岩。
The Neoproterozoic strata are preserved relatively intact in Quruqtagh of the Tarim Basin,which was evolved from the Early Nanhua volcanic rock-clastic rock deposit to the Late Nanhua-Early Sinian clastic deposit and then to the Late Sinian clastic rock-carbonate rock deposit.Four periods of glacial deposit were developed in this area,i.e.,Bayixi,Altungol,Tereeken and Hankalchough.As well as four phases of volcanism including Bayixi,Altungol,Zhamokti and Shuiquan.In Quruqtagh region,the continental margin rift was developed during the Neoproterozoic.The Early Nanhua was the strong tensional faulting stage,and then the transitional stage from faulting to depression lasted from the Late Nanhua to the Early Sinian.The stable subsidence stage was developed during the Late Sinian.Taking Xingdi Fault as the boundary,the southern and northern areas show different tectono-sedimentary evolution characteristics.In the Early Nanhua,the southern area was the volcanic rock eruption center and became the volcanic rock highland,while the northern area was the rift valley depocenter where the onshore-continental shelf sedimentary system was formed,resulting in the tectonic framework high in the south and low in the north.During the Late NanhuaEarly Sinian,the south area was dominated by delta deposit,while the continental shelf sedimentary system was developed in the north area,also showing the previous tectonic characteristic of"high in the south and low in the north".In the Late Sinian,the difference between sedimentation in the southern and northern area was weakened.The carbonate rock platform was developed in the southern area,and the northern area presented the diamictic continental shelf deposition system of clastic rock and carbonate rock.From the Late Nanhua to the Sinian,the volcanic activities ceased in the southern area,while many episodes of volcanic rock were developed in the northern area.
