摘　　要：作者继１９９３年１０月在赣东北蛇绿混杂岩带中首次发现晚古生代深水相放射虫硅质岩之后，经过１９９５年和１９９６年两次野外工作，又在该混杂岩带中及其两侧多处发现了含晚古生代放射虫的硅质岩及其深水相的沉积组合。从而为华南晚古生代或古生代—中生代洋盆的厘定，以及华南大地构造格局的再认识。After discovering of the Late Palaeozoic deep sea facies radiolarian silicolite in northeastern Jiangxi ophiolitic melange belt at first in October 1993, the authors found the same kind of rock again in many places in the belt and besides it in fieldwork in 1995 and 1996. The discovery provides convincingly new evidence for defining the basin in Southern China in Late Palaeozoic or Palaeozoic Mesozoic and recognizing the architectonic pattern of Southern China.
