摘    要:以地层划分、对比、沉积岩建造、火山岩建造、侵入岩浆活动和变质变形等地质记录为基础,以板块理论为指导,对福建省大地构造单元进行了重新认识和划分。将福建省区划分为华夏地块( Ⅴ --3) 、东南沿海岩浆弧( Ⅴ--4) 和闽中结合带( Ⅴ--7) 等3 个Ⅱ级构造单元,武夷古弧盆系( Ⅴ--3-- 1) 、南平-宁化( 夭折) 裂谷( Ⅴ--3--2) 、闽西南陆表海盆地( Ⅴ--3--3) 、闽东沿海岩浆弧( Ⅴ--4--1) 和松溪-尤溪蛇绿混杂岩( Ⅴ--7--1) 等5 个Ⅲ级单元,以及建宁古弧后盆地( Ⅴ--3--1--1) 等18 个Ⅳ 级构造单元。

关 键 词:大地构造单元  闽中结合带  福建省

Abstract:Based on geological records from stratigraphic division and correlation,sedimentary and volcanic formation,magmatic activities,deformation and metamorphismthe,the author makes a new division on the tectonic units of Fujian region with the guidance of plate theory. It can be subdivided into three second-order tectonic units, five third-order tectonic units and eighteen fourth-order tectonic units. The second-order tectonic units include Cathaysia Massif ( V-3) ,magmatic arc of coastal Southeast ( V-4) and conjunctive zone of central Fujian ( V-7) . The third-order tectonic units contain ancient arc-basin System of Wuyi ( Ⅴ-3-1) ,Nanping-Ninghua ( failed ) rift ( V-3-2) ,epicontinental sea basin of southwest Fujian ( V-3-3) ,magmatic arc of coastal eastern Fujian ( V-4-1) and Songxi-youxi ophiolite mélange ( V-7-1) . The fourth-order tectonic units consist of the Jianning ancient back arc basin and other seventeen tectonic units.
Keywords:tectonic unit  conjunctive zone of central Fujian  Fujian Province
