西昆仑山前甫沙—克里阳地区中新生代构造事件的裂变径迹证据及其地质意义
Fission track evidence for Meso-Cenozoic tectonic event of Fusha—Keliyang area in piedmont of the western Kunlun Mountains and its geological significance
摘要
Abstract
The Fusha—Keliyang area is located in the conjunction region of Tarim Basin and western Kunlun Orogenic Belt, which has a special tectonic location and complex evolutionary history. Zircon, apatite fission track dating and time-temperature thermal history modeling combined with field geological survey and seismic data were carried out to analyze the uplifting history of the Fusha—Keliyang area.The results show that the Fusha—Keliyang area undergoes five cooling events which occurs in the Late Triassic, Late Jurassic, Late Cretaceous, Early Miocene and Pliocene. The five cooling events have good response relationship with the regional background and field geological characteristics. The Late Triassic uplift event has the characteristics of long-term overall uplift, which lays the foundation for the late hydrocarbon accumulation. The Pliocene uplift event makes the source rock, faults, trap couple with each other in the study area, which leads to oil and gas accumulation in the late stage, and plays an important role in controlling the hydrocarbon accumulation in the area.关键词
