摘要
托莫尔日特蛇绿混杂岩带是柴北缘早古生代蛇绿混杂岩带东段的重要组成部分,亦是整个柴北缘地区各蛇绿混杂单元组合、出露较为齐全的地段之一,其中放射虫硅质岩在蛇绿混杂岩带中首次发现。托莫尔日特蛇绿混杂岩岩石学、岩石化学、地球化学等特征表明,其具有大洋中脊向岛弧蛇绿岩过渡的特点。
Tuomuoerrite ophiolite melange belt is the main part of Early Proterozoicophiolite melange belt in the north margin of Qaidam basin and have a complete ophiolitemelange unit assemblage. In the belt radiolarian silicalite was first found. The petrologicalpetrochemical and geochemical features indicate that the ophiolite has a transitive featurefrom mid --ocean ridge to island arc.
