摘要
本文依据构造、地球化学、地球物理资料的综合分析,特别是对含地幔岩包体的基性岩带的研究,提出了郯庐断裂南延带是呈两个主干夹一断裂束的形式,从湖北广济,经江西修水,湖南连云山、衡阳、江永,直抵广西大容山—六万大山(广济—六万大山断裂),南延带已趋近郯庐断裂尾端。以广泛的韧性变形变质代替了中带的破裂大平移。它是华南的一条重要动-热-地球化学分界带。
Based on the structural geochemical and geophysical information, especially on the researches on basic rocks with ultramafic xenolith, the author suggests that the south elongation of the Tancheng-Lujiang fault extends from Guangji, Huhei province, through Jiangxi Province, Hengyang and Jiangyong, Hunan Province, into Dayong mountain—Luwan mountain, Guangxi (Guangji—Luwan mountain fault). The south elongation is near the end of the Tancheng-Lujiang fault, and appears as strong ductile-deformation-metamorphism instead of break-giant strike slip of the middle part. It is an important dynamic-thermal-geochemical boundary zone in south China.
