| Abstract: | There exist volcaniclastic rocks in Ordovician within the Yongxin-Congyi area,
Jiangxi, which were found firstly by the authors. In this paper starting from the charac-
teristics of lithologic charater and lithofacies of the strata and based on the field work and
lithologic-mineral indentification layer by layer. the authors investigate the division of the
lithostratigraphic unit again in Ordovician there. The implication of the formations are col-
lated and stipulated on the basis of the distinctive characteristics of lithologic character and
lithofacies. and the ages of the formations are discussed. |
