摘要
在确定出北加里曼丹大地构造单元的基础上,结合分析其内新生代岩浆岩性质及其大地构造环境,认为新生代北加里曼丹是卢卡尼亚(Luconia)陆块和巽他陆块碰撞的造山带,并提出"北加里曼丹新生代碰撞造山带"的概念。该造山带经历了边缘造山带-内部造山带-边缘造山带相继转化的过程,它控制了加里曼丹的区域成矿作用,特别是晚渐新世-中中新世北加里曼丹内部造山带的逆冲叠瓦阶段是加里曼丹区域成矿的最重要时期。
Based on confirming the geotectonic units in north Kalimantan and analyzing the nature of Cenozoic magmatic arcs and related geotectonic settings, the author thought North Kalimantan was an collision orogen formed by the collision between the Luconia continental block and the north margin of Sundaland. It is called 'Cenozoic collision orogen of north Kalimantan' by the author. This orogen saw a very complicated history from interior orogen to peripheral orogen and to interior orogen again. It is suggested that regional metallogenesis in Kalimantan be controlled by these geological and tectonic processes.The imbricate thrusting stage during late Oligocene-middle Miocene interior orogen was the most important epoch of regional metallogenesis in Kalimantan.
