胶州湾及其周围地区是北东方向大断裂带发育的鲁东隆起的一部分,中生代岩浆活动较强烈。出露岩系主要是中生代的陆上碎屑岩和火山岩类地层,以及燕山期岩浆岩,局部地方有前震旦纪变质岩系。区内广泛被海水及第四系沉积覆盖,地质观察受到限制,构造研究尚存在许多悬而未决的问题。1975年,航测九○七队应青岛市要求在本区进行
Jiaozhou Bay and its surrounding areas are part of the Ludong uplift developed in the northeastern major fault zone and the Mesozoic magmatic activity is intense. Exposed rock series are mainly Mesozoic terrestrial clastic rocks and volcanic rock formations, and Yanshanian magmatic rocks, local places have pre-Sinian metamorphic rocks. The area is widely covered by seawater and Quaternary sediments, and geological observation is limited. There are still many outstanding issues in the study of tectonics. In 1975, the aerial survey team of 907 should be required by Qingdao City in this area
