| TECTONIC EVOLUTION FEATURES OF THE EAST CHINA SEA AREA PLATFORM BEFORE MESOZOIC |

|
| Abstract: |
| The crust evolution of the East China Platform bordering on Korea Peninsula and southwest Japan was characterized by platform trough system before Mesozoic. 1. Korea Peninsula is located at eastern Sino-Korean platform. From the middle-proterozoic to early-palaeozoic, this area entered a sedimental stage of the platform type. The platform syneclise and platform anteclise were provided with sea and palaeoland evolution features respectively. After Caledonian movement, Rimjin-gang to Yannan miogeosyncline zone of middle-devonian to early-carboniferous was regenerated following the Kyonggi-Jiaodong massif(platform anteclise) break-up. 2. Yantze platform extends to east to connect with Kyonggi massif of P. R. K. and to south with the tectonic zone between Oki and Hida of Japan. 3. the eu-and miogeosyncline system of southeast China ar middle-proterozoic to early-Palaeozoic extended to east to connect with Honshu geosyncline system of southwest Japan. 4. Cathaysian massif located on the Nanhai-Donghai Sea platform was united with "Nanfang palaeocontinent" of Japan to form "eastern Asia continental massif" at early Palaeozoic. 5. The variscian-Indo-Sinian geosyncline system of Japan-Taiwan_Philippines was regenerated after the eastern Asia plate after later-Palaeozoic. |
