| 摘 要： | 东北地区处于古亚洲构造域和西太平洋构造域的叠合部位.该区地幔热柱存在8个地质标志:①南北以西伯利亚板块和华北板块太古代基底(断裂)为界,东西以变质核杂岩体分布为界,基本与日本海毗邻的范围为亚地幔柱的规模；②在佳木斯-牡丹江缝合线内见有科马提岩、苦橄岩,可能为地幔热柱的中心；③水系分布呈放射状及莫霍面分布为松辽盆地幔隆起一致；④典型的热穹隆状态；⑤以花岗岩为主的火成岩省；⑥中生代基性玄武岩基本落入Nb/Ta-Nb图解的地幔柱范围；⑦形成坍塌裂谷特征；⑧岩石圈地幔呈蘑菇云状上涌,地震层析资料证实与太平洋板块俯冲具有相辅相成关系.中生代地幔热柱成矿成藏作用的时空分布具有同时代、同火成岩构造控制,山岭成矿,盆地成藏特征.从He及Ar同位素组成阐明金属矿床与油气田的同源性,分析了幔枝构造是在地表的表现形式,无疑对当今深部找矿及海相油气田的勘查具有理论指导意义. |
