滇西北宁蒗西漂落二叠纪峨嵋山玄武岩组中古勃贝(GUBLERIA)的发现及其地质意义

DISCOVERY AND ITS GEOLOGICAL SIGNIFICANCE OF GUBLERIA FROM PERMIAN EMEISHAN BASALT FORMATION IN NINGLANG XIPIAOLUO OF NORTHWESTERN YUNNAN

本文报道的Gubleria腕足类化石产于云南省宁蒗县西漂落,层位为二叠纪峨嵋山玄武岩下部的灰岩夹层。它与Verbeekina共生,说明古勃贝的时限可以下延(早二叠世晚期),并且意味着峨嵋山玄武岩组的穿时性(从早二叠世晚期到晚二叠世)。

The Gubleria of brachiopodous fossil reported by this paper having a para-genetic relationship with the Verbeekina is contained is the limestone interca-lation belonging to the lower part of the Permian Emeishan Basalt Formation distributed near the Xipiaoluo village of the Ninglang county, Yunnan provi-nce. It illustrates that the time limit for Gubleria could extend down to the late period of Early Permian and implies that there was the diachronism of the Emeishan Basalt Formation(late Early Permian to Late Permian).
