加里东旋回

北部蛇绿构造混杂岩带不同时代蛇绿岩广泛分布，至少经历了前晋宁旋回，晋宁&加里东旋回，海西一印支旋回三大旋回的洋陆转换。

The northern ophiolite melange belt contains various ophiolites of different times , and at least experienced three ocean-continent cycles , i.e. , pre-Jinning cycle , Jinning Caledonian cycle and Hercynian Indo-sinian cycle .

石油化学成分最大值与加里东旋回、海西旋回和阿尔卑斯旋回中期的最大海侵相一致。

They are in accordance with regressive geotectonic phases , of which the maximum values appear to be correspond to the largest-scale marine transgressions occurred in Caledonian cycle , Hercynian cycle and middle phase of Alpine cycle .

结合本分队测得Pb-Pb同位素视年龄值（423±1）Ma，确定其为加里东造山旋回的产物，属科迪勒拉&加里东型花岗岩及晚造山期花岗岩，形成于板块消减、褶皱隆起造山环境。

Combine with Pb Pb isotope age ( 423 ± 1 Ma ), it is considered as the product of Caledonian orogenic cycle and belongs to Cordilleran Caledonian type and late orogenic stage granite . It was formed in the orogenic environment of plate subduction and fold uplift .
