摘 要:大地构造环境对玄武质岩浆成分有影响,但却不是主要的,更不是唯一的因素。

Up to date the reserves discovered at shallow targ ets has exceeded 70% of total in Bohai Sea.Neotectonismis chara cterized by:(1)different Q and N center of subsidence,and angular unconformity b etween Q and N;(2)basalt effusion and magma activities frequently;(3)regular dis tribution of earthquake center;(4)intensive later faults (15-2Ma)forming multit ude anticiline in Nm-Ng formations.

目前浅层的油气储量占总储量的70%以上,这是由于海域新构造运动控制了晚期成藏,表现为:第四纪沉降中心与Nm晚期沉降中心不吻合,使得Q与N之间地层呈角度不整合;玄武岩喷发及岩浆活动频繁;沿渤南及郯庐断裂带天然地震震中有规律分布,晚期(15~2Ma)断裂极其发育,在Nm—Ng组地层内形成众多的背斜圈闭。

The petrological study and studies in element and isotopic geochemistry indicate that the pluton belongs to high-potassium calc-alkaline I-type granite, whose magma came from basic basalt in the thicken crust bottom by partial melting, and are of syn-collisional features. The pluton provides a direct petrological evidence of the plate collision and amalgalation.
