| 摘 要： | 川西盐边、石棉两地的基性超基性杂岩和火山岩系为世界上少见的元古代高钛到蛇绿岩,这意味着该区曾经历过海洋化过程和板块运动。故康定至攀枝花一线的“康滇地轴”应为原始扬子板块西缘的元古代造山带。文章评述了该区蛇绿岩及有关基性超基性杂岩的研究现状,提出重建该造山带地质历史的思路和线索。

| Abstract: | The mafic-ultramafic complex and volcanic rock series from Yanbian and Shimisn,westernSichuan,China are recognized as a rare Proterozoic high-Ti ophiolite suite in the world. This suggeststhat the area underwent oceanization and plate movement during Proterozoic time. Therefore the"K8ngdian Axis "of this area should be considered as a Proterozoic orogenic belt on the west border ofYangtze paleo-plate. ThiS paper reviews the present situation of the research on the ophiolite and othermagic-ultramafic rocks and proposeS a comprehesive clue for the reconstruction of the seological evolution history of the orogenic belt. |
