【摘要】：在郯廬斷裂帶以東,包括蘇北—南黃海地區(qū)在內(nèi)的下?lián)P子區(qū),晚白堊世—古近紀(jì)時期,在太平洋板塊由南向北俯沖消減的運(yùn)動過程中,東亞大陸被牽引,發(fā)生了由南向北的大型左行平移走滑運(yùn)動和巖石圈上地殼遞進(jìn)減薄拉張的伸展拆離構(gòu)造運(yùn)動。從蘇、皖南的南陵—廣德、句容—常州斷陷盆地開始,經(jīng)蘇北東臺、鹽阜坳陷—南黃海南部的青島坳陷,再向北至南黃海北部的煙臺坳陷,形成了3條呈NE—近EW走向的斷陷盆地構(gòu)造帶。盆地為具有南斷北超的箕狀半地塹結(jié)構(gòu),呈多米諾骨牌式自南向北排列;并與其間近E-W走向的南京—南通—勿南沙和濱�！宵S海中部的嶗山古生界地層的核部雜巖褶隆帶,共同構(gòu)成較大區(qū)域范圍的盆—嶺構(gòu)造。這一期構(gòu)造運(yùn)動一方面再次改造了下?lián)P子區(qū)海相古生代盆地,為海相古生界烴源巖系在經(jīng)歷了抬升剝蝕后的再次深埋,以及晚期二次生烴提供了可能性;另一方面也控制了中新生代油氣的生成與聚集分布。
[Abstract]:In the Lower Yangtze region east of the Tanlu fault zone, including the Huang Hai area of northern Jiangsu and southern Jiangsu, the East Asian continent was towed during the late Cretaceous to Paleogene period during the subduction and subduction of the Pacific plate from south to north. A large left-lateral lateral strike-slip movement and a progressive thinning and tensioning extension of the upper lithosphere occurred from the south to the north. Starting from the Su, Nanling Guangde, Jurong Changzhou faulted basin in southern Anhui, through the Dongtai basin in northern Jiangsu, the Qingdao depression in the south of Yanfu depression and the southern Huang Hai depression, and then to the Yantai depression in the north of Huang Hai in the north, Three faulted basin tectonic belts with NE-near EW strike were formed. The basin is a half-grain-shaped semi-graben structure with the southern fault-north superstructure, which is arranged from south to north in a domino-type manner, and the core complex fold belt of the Paleozoic strata of the Laoshan Mountains in the middle of the Nanjing-Nantong-Fenansha and Binhai South Huang Hai, which is near the E-W strike. The basin-ridge structure in a large area is formed together. On the one hand, the tectonic movement remade the marine Paleozoic basins in the Lower Yangtze area, which provided the possibility for the marine Paleozoic source rock series to be buried again after the uplift and denudation, as well as the late secondary hydrocarbon generation. On the other hand, it also controls the generation and accumulation distribution of Mesozoic and Cenozoic oil and gas.
