摘　　要：关于华南大地构造属性,长期存在古陆或克拉通与地槽褶皱带或造山带两种观点。根据华南很少出露早前寒武纪地质体,广泛发育1.0Ga以后的巨厚地槽相沉积物,经历了1.0Ga以后的多旋回构造运动,发育多期次花岗岩类等事实,笔者认为华南是造山带,而非古陆。考虑到世界著名地台或古陆均不产钨矿,而华南是世界最重要的钨矿省,本文通过分析钨等元素成矿地球化学原理,结合介绍华南含钨花岗岩类的地球化学特点及其形成构造背景,从区域成矿规律角度论证了华南是造山带。The geotectonic nature of the South China has been debated for a long time between the Old Land or craton and the Folded Geosyncline or orogenic belt. The authors insist on that it is an orogenic rather than a cratonic area, because South China is rare of Early Precambrian terrains, widespread of huge volume of geosyncline-facies sediments with age of 〈1.0 Ga, significantly affected by multi-cyclic tectonic movements after 1.0 Ga, and developed with multistage Phanerozoic granitoids. Considering that famous platforms or Old Lands in the world do not contain tungsten deposit, and that South China is the most important tungsten metallogenic province in the world, in this paper the authors introduce the geochemical principles in W mineralizing processes, the geochemical characteristics and genetic tectonic setting of W-bearing granitoids in South China; and thereby, through study of regional mineralization, confirm that the South China is tectonically an orogenic belt.
