Jebel Abd Al Aziz是叙利亚东北部地形特征最为突出的地区,是一个大的地表背斜。从1988年至1995年,Unocal公司进行的一项构造和地层综合研究认为,Jebel Abd Aziz背斜是由原先的一个地堑反转而成。了解Jebel Abd Al Aziz地区复杂的地层构造历史。对阿拉伯构造板块北部的油气勘探开发具有重要的意义。产油气区与上新世～更新世构造反转地区的关系相当密切就说明了它的重要性。 本文对记录在该区地层里的构造演化情况进行了阐述。在Jebel Abd Al Aziz构造发展以前,Senonian(kz)陆棚碳酸盐沉积由土耳其向南前积至沿叙利亚中西部至东北部延伸的Palmyride—Sinjar断槽。碳酸盐层系的陆棚边缘位于叙利亚边介的南部并与边介近似平行。在Jebel Abd Al Aziz地区,细粒的盆地相泥岩沉积在一套海侵的薄层厚壳蛤生物碎屑岩之上。早Masstrichtian期(k_2),一个东西向地堑在现今的Jebel Abd Al Aziz位置上发展起来。地堑内部的一些构造断块受再次活动的北西走向和北东走向断层所限。地震资料表明,该裂谷盆地边缘剥蚀较深。沿着区域上老横切断层的走向而分布的盆地边侧有一些受切割的谷地,出露石炭系和较老的地层。在盆地边介的断层崖处形成了一些滑积层,河口处还发育了一些小的浊积扇。浊积砂体的古流方向资料与地震图上?
Jebel Abd Al Aziz is the most prominent feature of the terrain in northeastern Syria and is a large surface anticline. From 1988 to 1995, a structural and stratigraphic study conducted by Unocal held that the Jebel Abd Aziz anticline was inverted from the original one. Get to know the history of complex stratigraphic structures in the Jebel Abd Al Aziz area. It is of great significance to oil and gas exploration and development in the northern part of the Arabian tectonic plate. The close relationship between the oil-producing area and the Pliocene-Pleistocene tectonic inversion area illustrates its importance. This paper describes the tectonic evolution recorded in the strata of this area. Prior to the development of the Jebel Abd Al Aziz tectonics, the Senonian (kz) continental shelf carbonate deposition from South Turkey pre-empted to the Palmyride-Sinjar fault extending along the central-western to the northeast of Syria. The margins of the carbonate shelf are located in the southern Syrian border and are approximately parallel to the sidelines. In the area of Jebel Abd Al Aziz, fine-grained mud facies sediments are deposited on a set of transgressive thin-clap shell clastic bioclastic rocks. As early as Masstrichtian (k_2), an east-west graben developed at present-day Jebel Abd Al Aziz. Some structural faults within the graben are limited by the reactivated North West strike and the North East strike. Seismic data show that the rift basin edge erosion deeper. Some of the cut valleys on the sides of the basin distributed along the direction of the old transverse faults in the area show the Carboniferous and older strata. Some slip strata were formed at the fault cliffs of the margin of the basin, and some small turbidite fans were also developed at the estuary. Triassic sand flow direction and seismic data?
