东海陆架盆地及其邻域岩浆岩时空分布特征
TEMPORAL AND SPATIAL DISTRIBUTION OF THE IGNEOUS ROCKS IN THE EAST CHINA SEA SHELF BASIN AND ITS ADJACENT REGIONS
摘要
Abstract
Two-dimensional seismic and gravity-magnetic data were processed and interpreted by the authors in order to study the temporal and spatial distribution of igneous rocks in the East China Sea Shelf Basin and its adjacent regions. Data from the land, mainly from Zhejiang and Fujian provinces were collected for the purpose of correlation. Igneous rocks are widely distributed in Zhejiang and Fujian. They occur in a NE trending to the north and NNE trending to the south of 28 N. They are shallowly buried and controlled mainly by major faults. The igneous rocks offshore are mainly distributed upon uplifts or along the fault boundaries of depressions. Temporally, the igneous rocks in the study area can be subdivided into four stages, i. e the Yanshan stage, Sichuan stage, Huabei stage and Himalayan stage and spatially occur in four zones, say the Zhe-Min uplifted zone, Central uplifted zone, Diaoyu Island folded uplifting zone and Ryukyu arc zone.关键词
