| 摘 要： | 在西南某沟的地质调查中对原先划定的二叠系地层产生质疑,传统的同位素定年耗时长、花费大,我们用争议地层的微量元素配分模式和研究区寒武系地层以及其他地区的二叠系地层的微量元素配分模式进行比较,发现争议地层的微量元素配分模式更接近于研究区寒武系的地层的配分模式,而与二叠系地层的配分模式有较大的差异,从而将争议地层划归为寒武系地层。

| Abstract: | The original demarcated Permian strata have been doubted in the geological survey on a southwest ditch.The traditional isotopic dating is time consuming and expensive.By comparing the research area with other areas using trace elements distribution pattern,we discovered that trace element distribution pattern of the disputed strata which has much more difference with the distribution pattern of Permian strata,is more close to the Cambrian strata in the study area,thus the disputed strata is classified as the Cambrian strata. |
