As far as the architecture of the south Dabie metamorphic terrain is concerned, there have been lots of different opinions for a long time. Wang et al. (1990, 1992) thought of it was a continuous terrain. Okay (1993) held that it consistes of two different tectonic terrains: the 'hot' and 'cold' eclogite belt. Liu and Wang (1998) held that it is composed of different metamorphic blocks through 'melange' in depth. For this reason, we have choiced Hualiangting reservoir of Taihu county as the study area treat eclogite as the investigated objection in this thesis, and employ the detailed 1 :10000 geological mapping, methods of Petrography and electonic probe anaylsis to probe into the architecture of the south Dabie metamorphic terrains. In the light of the eclogite occurrenc in the field, the analysis of Petrography, the research on metamoiphic P-T path and condition of the peak metamorphic P-T condition, the eclogite in the Taihu area of Dabieshan have been classified into three types eclogite from the south to the north: The zhujiachong type eclogite; The Daba type eclogite; (3) The Jinheqiao type eclogite, their mineral composition, structure, and mineral component vary continuously. These eclogites have the same rnetamoiphic stages, P-T evolution pattern, and their peak P-T condition varies continuously. The zhujiachong type eclogite is formed in the high pressure metamoiphic environment. The Jinheqiao type eclogite is formed in the typical ultra-high pressure environment. The Daba type eclogite is formed in the transformed metamorphic environment between high pressure and ultra-high pressure metamorphism. All these evidences show that the south Dabie metamorphic terrain is a continuous metamorphic block and no large fault ever existed.
