Doshan地区新发现的底辟构造具有典型的双重性，其浅层碳酸盐岩底辟在叠加于下伏深部底辟构造上的同时，还保持与下部底辟构造形态的一致性。底辟构造规模普遍较小，平面多呈NW-SE向展布。综合区域应力背景、塑性层形变、裂解气显示等相关要素分析，认为底辟构造属深源型底辟，其形成发育主要受控于晚白垩世。南图尔盖盆地大规模走滑、抬升变形过程中，基底深部古断裂再次活动导致深部物质沿断层小规模上拱。此类构造的发现在为构造研究提供全新模式的同时，也为南图尔盖盆地油气勘探提供了一个新的领域。在位于斜坡-潜山带的底辟构造，有着良好的油气成藏条件，是寻找相关构造、岩性油气藏的理想区域，应作为后期油气勘探的重点。

The diapir structure newly defined in Doshan area ,South Turgai Basin is a typical duplex structure .The lower carbonate diapir superimposes on the deeper one ,and maintains the consistency of structural configuration with that of the latter at the same time .These small-scale diapir structures are generally on NW-SE trend .They are recognized as deep-source diapirs based on their regional stress background ,plastic deformation ,and pyrolysis gas show .Their development is mainly controlled by the upswelling of deep materials along small-scale faults due to the revitalization of deep base paleo-faults during the Late Cretaceous large-scale strike-slipping and uplifting deformation in southern Turgai Basin .The dis-covery of this kind of structures not only provides a new mode of tectonic research ,but also a new domain of petroleum exploration in southern Turgai Basin .Diapir structures located in slope-burial hill belt have favorable accumulation condi-tions,and are favorable targets for discovering structural and/or lithologic hydrocarbon reservoirs .
