摘要/Abstract

摘要： 华南板块在泥盆纪位于古赤道附近，早—中泥盆世之交，广西那艺古纬度为 0°36'，泥盆纪—石炭纪之交贵州睦化地区古纬度为4°10'10″，赤道附近温湿的气候使华南板块上各种生物，无脊椎动物，脊椎动物，植物高度繁盛，发育，都有很高的分异度。泥盆纪时期华南板块向北缓慢移动，移动速率为0.22 ～0.26cm/a。其原因可能与特提斯洋的活动有关。

Abstract: The Southern China plate is located near paleoequator in Devonian. Nayi, Guangxi, is at 0°36'N at Early-Middle Devonian. Muhua, Guizhou, was at 4°10'12''N at Devonian-Carboniferous. It was in the warm and moist climate near paleoequater that the various kinds of biota such as invertebrate, vertebrate, plant developed separately, and had higher diversification. Carboniferous rock deposited at the same time. South China plate slowly moved from south to north in Devonian. The drifting velocity was 0.25-0.26cm per year. The drift of south China Plate maybe related to activity of Terthys ocean.

Key words: Devonian, south China plate, paleomagnetism
