【摘要】 通过对韩江凹陷重磁异常、地震剖面以及周边地质资料综合分析认为,在韩江凹陷内确定断裂12条,其基底岩性由四种类型组成——中生代酸性—中性岩浆岩、中生代中基性岩浆岩、中生代中酸性火山岩夹沉积岩及时代未定地层.更多还原

【Abstract】 By means of comprehensive analyses of gravity-magnetic anomaly,seismic section and surrounding geological data in Hanjiang Sas.it is believed that the basement lithology can be divided into 4 kinds;the Mesozoic intermediate-acidic igneous rocks,the Mesozoic intermediate -basic igneous rocks,the Mesozoic intermediate-acidic volcanic rocks with few sedimentary rocks,and sedimentary rocks or epimetamorphic rocks of undefined stratigraphic-time. 12 faults can be identified更多还原
