| Abstract: | In this paper the fine structure of crust-mantle transition zone in Western Yunnan Province is analysed and discussed based
on the reflection phases from Moho-discontinuity in Project Western Yunnan 86–87. It shows that in two points: in the north
27.64 km from shot point Jinggu and south 58.74 km from shot point Zhiti, there are transition zones of group of thin layers
with inverse velocity. These two reflection points are both situated in the lower velocity anomaly zone in the top of upper
mantle. The crust of this region is more seismicity. Maybe the unusual structure of this transition zone is related with the
characteristics of this region. This paper discusses the possible geological interpretation model for this transition zone,
and also makes suggestion about its application in earthquake prediction.
