摘要
赛里木湖—博罗霍洛地区大地构造演化经历了早元古代前地槽阶段、中元古代至古生代地槽阶段、三叠纪至侏罗纪地台阶段和白垩纪至新生代地洼阶段。本区经历二次造山作用 ,晚石炭世末的因尼卡拉运动使全区隆起褶皱成山 ,形成本区第一代山脉 ;第四纪强烈的断块运动造成本区今日所见的第二世代山脉——地洼断褶带山脉及断陷湖泊——赛里木湖。由北至南可分为 10个 级构造单元。中元古代的热水沉积、泥盆纪的岩浆侵入和火山喷溢。
The geotectonic evolution in Sailim Bolohuoluo region has involved four stages: pre geosynclinal stage in the Proterozoic, geosynclinal stage from Mesoproterozoic to Palaeozoic, platform stage from Triassic to Jurassic and diwa stage from Cretaceous to Cenozoic. The region has undergone two orogeneses: compression folding orogenesis of Yinikala orogeny in late Carboniferous formed the first period mountains, intracontinental block faulting orogenesis in the Quaternary formed the second period mountains of bruchfaltung and fault trough lake (Sailim Lake). The tectonic units of Sailim Bolohuoluo region are divided from north to south. Hot water sedimentation in Mesoproterozoic, action of volcanic eruption or magmatic intrusion in late Devonian and Carboniferous are main metallogenic thermal events in this region.
