摘要 根据合肥盆地及周边地表地质、地震剖面、同位素测年及MT等新资料的综合研究,提出中-新生代合肥盆地的基底是一个不同构造类型基底的叠合与复合.上古生界以前的基底以六安断裂为界,其北为华北板块陆壳型-过渡壳型结晶基底及其上的华北克拉通-被动大陆边缘盆地沉积的上元古-下古生界基底;其南为大别型结晶基底及其上的北淮阳弧后盆地沉积的上元古-下古生界变质基底,而上古生界基底属于弧后前陆盆地型沉积.六安断裂是合肥盆地部位北大别弧、北淮阳晚元古-早古生代弧后盆地在早古生代晚期-晚古生代早期与华北板块的弧-陆碰撞缝合线.

Abstract: Based on comprehensive study of new data of outcrops by edge of the Hefei basin, seismic sections in the basin, isotopic age and magnetotelluric sounding, etc., this paper suggests that the basement of the Hefei basin, in Mesozoic and Cenozoic, is stacked and compounded by deferent tectonic types of basements. The pre-Upper Paleozoic basement is divided by the Liu’an Fault, north of which is crystalline basement of continental and transitional crust of the North China Plate and Neoproterozoic-Lower Paleozoic sedimentary basement formed in the North China Craton and its passive continental margin basin. To the south of the Lin’an Fault is crystalline basement of the Dabie Massif and Neoproterozoic-Lower Paleozoic metamorphic basement formed in the Beihuaiyang Retroarc Basin. The Upper Paleozoic basement rocks under the Mesozoic and Cenozoic strata in the Hefei basin belongs to the deposits in retroarc foreland basin. The Liu’an Fault is the suture of arc-continent collision between the North Dabie Arc-Beihuaiyang Retroarc Basin of Neoproterozoic-Ealy Paleozoic and the North China Plate in the Hefei basin, which collided in late Early Paleozoic to early Late Paleozoic.
Key wordsThe Hefei Basin   Basement of the basin   Tectonic attribute   Division of tectonic units   The Liu’an Fault
