摘要
研究断裂带控制的火山—沉积建造及古生物区系、陆缘岛弧碰撞—造山型花岗岩带、俯冲火山弧根带阿拉斯加型镁铁—超镁铁环状杂岩和造山期或造山期后山前逆冲推覆构造等特征后认为澜沧江断裂带不是冈瓦纳板块与扬子板块的结合带,而是他念他翁山山前与昌都—兰坪—思茅(弧后)前陆盆地之边界断裂。
According to the study of volcano - sedimentary formation, palaeobiocoenosis, epicontinental island arc collision - orogenic type granite zone, Alaska type marie - uhramafic ring complex of subducted volcanic arc root zone and orogenic epoch or postorogenic piedmont thrusted nappe, etc, we don' t think the Lancangjiang fault zone is the conjunction zone of Gondwana Plate and Yangzi Plate. In our opinion, it is the boundary fault of Taniantaweng piedmont and Changdu - Lanping - Simao ( back - arc) foreland basin.
