Based on a comprehensive study on faciology, petrology and petrogeochemistry, the ignimbrites widely distributed in Mesozoic volcanic basin in South Jiangxi are divisible into three types namely the clastic flow, the surge flow, and the subvolcanic types, of which the genetic mechanism has been discussed in this paper.
