| Abstract: | A radiolarian fauna,consisting of 32 species belonging to 1 7 genera,found in Laochang and Nanpan of Lancang County and Bangsha of Jinghong County,is described in this paper. The fauna can be divided into 3 assemblage zones. The sequence of these zones is listed ascendingly as follows : (1 )F ollicucullus assemblage zone,collected from the upper part of Laba Group in Nanpan, Late Maokou-Early Longtan. (2) Neoalbaillella optima assemblage zone ,occurring in the upper part of Laba Group in Nanpan and the middle part of Laochang Formation in Laochang, Late Longtan. (3) Neoalbaillella ornithoformis assemblage zone preserved in the upper part of Laba Group in Nanpan and the chert interbed of volcanic rocks in Bangsha,Early Changxing. The geological times of the litho-stratigraphic units are discussed based on the three assemblage zones. |
