文章对温都尔庙群的绢云石英片岩进行锆石 SHRIMP测年，大致可以分为850~950Ma和450~550Ma两组年龄，认为前一组年龄为该群变质年龄，后一组为加里东期岩浆热事件叠加年龄，故温都尔庙群时代归属应为新元古代。
文章對溫都爾廟群的絹雲石英片巖進行鋯石 SHRIMP測年，大緻可以分為850~950Ma和450~550Ma兩組年齡，認為前一組年齡為該群變質年齡，後一組為加裏東期巖漿熱事件疊加年齡，故溫都爾廟群時代歸屬應為新元古代。

This paper conducted SHRIMP zircon dating on sericite quartz schistin Wenduermiao Group,and the re-sults showed that the ages could be roughly categorized into 850~950Ma and 450~550Ma.The author believed that first category of ages was the metamorphic age of the group,while the latter was Caledonian magma hydrothermal superimposed age.Therefore,the epoch of Wenduermiao Group should be in Neoproterozoic era.
