【摘要】:通過精細(xì)測量及觀測南京、巢湖、浙江地區(qū)25個(gè)露頭點(diǎn)露頭資料和典型剖面測量以及資料收集整理,綜合分析認(rèn)為下?lián)P子陸域主要發(fā)育下寒武統(tǒng)荷塘組、下奧陶統(tǒng)寧國組(大灣-牯牛組)、上奧陶統(tǒng)五峰組-下志留統(tǒng)高家邊組、下二疊統(tǒng)棲霞組、上二疊統(tǒng)龍?zhí)督M、上二疊統(tǒng)大隆組6套區(qū)域性主力烴源巖。烴源巖的發(fā)育受多種因素控制,在下?lián)P子地區(qū)主要受構(gòu)造演化、最大海平面變化、古地貌單元、沉積環(huán)境等因素控制。在構(gòu)造演化控制的特定古地理格局下,大規(guī)模海侵期控制了烴源巖發(fā)育層位,古地貌單元控制了烴源巖分布范圍,沉積環(huán)境控制了烴源巖的類型。以下?lián)P子陸域烴源巖研究為對比基礎(chǔ),探討了尋找南黃海盆地?zé)N源巖的方向。
[Abstract]:Through fine measurement and observation of outcrop data and typical profile survey of 25 outcrop points in Nanjing, Chaohu and Zhejiang, and the data collection and arrangement, the comprehensive analysis is that the lower part of the Lower Ordovician of the Lower Ordovician in the Lower Ordovician of the Lower Ordovician is the Lower Ordovician in the Lower Ordovician (Dawan-Taurus Formation). There are 6 regional main source rocks in the Upper Ordovician Wufeng Formation, the Lower Annulian Group, the Lower Permian Qixia Formation, the Upper Permian Longtan Formation and the Upper Permian Daliang Formation. The development of source rock is controlled by various factors, and in the lower Yangtze region, it is controlled mainly by the structural evolution, the maximum sea level change, the ancient geomorphic unit, the sedimentary environment and other factors. In the specific paleo-geographical pattern of the structural evolution control, the large-scale sea-invasion period controls the source rock development horizon, and the palaeo-geomorphic unit controls the source rock distribution range, and the sedimentary environment controls the type of source rock. Based on the study of the following source rock of the Yangtze region, the paper discusses the direction of the source rock in the South Yellow Sea.
