There are two mistakes in researching the formation age of the ophiolite belts, China.
对中国蛇绿岩带形成时代的研究曾出现两个误区 ,第一个误区发生在 70年代以前 ,大多数地质学家主要依据混杂堆积中灰岩块体中生物化石来确定蛇绿岩带的形成时代 ,由于这些大化石所形成的时代一般都要比蛇绿岩带的形成时间早 ,它不能代表板块碰撞的真正时间 ;第二个误区发生在 70年代之后 ,广大地质工作者普遍利用放射虫来确定蛇绿岩带的形成时代 ,但是 ,在蛇绿岩带中有时出现两套放射虫硅质岩 ,一套属于外来移置体 ,与洋壳无关 ;另一套位于枕状玄武岩上 ,真正代表洋壳的残余。
