The Late Paleozoic strata are extensively exposed in Baoshan massif of western Yunnan. Research work has been rela- tively in detail and, as a result, many achievements have been obtained. However, the Devonian-Carboniferous boundary was previously considered to be of pseudoconformity contact. In recent years, through 1：50000 regional geological survey in Shidian area, we collected a large number of Famennian-Tournaisian conodonts in upper Heyuanzhai Formation which was previously as- signed to Middle-Late Devonian and confirmed that the sequence of sedimentary facies between Heyuanzhai Fornlation and over- lying Xiangshan Formation is a gradual transition relationship. Therefore, the authors propose for the first time that the Devonian- Carboniferous contact relationship is conformable contact, and this result will provide the latest information for the tectonic evolution of Baoshan massif.
