【摘要】 胶莱盆地位于郯庐断裂带东侧，是典型的拉张盆地，内部划分为诸城凹陷、柴沟地垒、高密凹陷、大野头凸起、莱阳凹陷、牟平──即墨断裂带、海阳凹陷。运用重力资料一级近似解法，定量计算了胶莱盆地基底埋深，结合磁异常解释等，本文重点讨论了盆地内主要断裂的形成时期，切割深度及空间演化。并进一步将诸城凹陷细分为胶县洼陷、集王疃洼陷、平度洼陷、马山构造带、刘家庄构造带、李党家构造带。讨论总结了该盆地构造特征及其发育规律，为该区油气勘探提供了新的认识与依据。更多还原

【Abstract】 Jiaolai basin locates on eastern side of famous Tan-Lu fault belt, and is a typical full-apart basin. It consists of Zhucheng depression, Caigou forst. Gaomi depression Dayietou uplift. Laiyang depression.Muping-Jimuo fault belt. and Haiyang depression. With first degree approximation method, We’ve calculated the buried depth of its basement from gravitic data.And, combined with meganetic data intepretation, discussed are the forming time, the cutting depth and the space evdution of several main faults in the basin. Further more. We’ve subdivided Naomi depreasin into Jiaoxian, Jiwangtan, and pingdu (three) sub-depressions, and Mashan, Liujiazhuang, Lidangjia (three) sub-tectonic belts. Also discussed are the basin characteristics and its developing law in this paper, thus giving the new idea to its oil and gas explora tion.更多还原
