摘要
粤北泥盆系发育在加里东运动不整合面之上,属于海西旋回早期沉积。该区泥盆纪海侵由南西往北东逐渐扩大随后又略微退缩,构成一个次一级的海侵-海退旋回;本文主要对沉积环境的地层、构造背景和古地理相进行初步研究和讨论,以期对后期矿床研究打下基础。
The Devonian System in north Guangdong was developed on the Caledonian unconformity surface. The Devonian marine transgression here advanced gradually from the southwest to the northeast followed by marine regression, forming an early Hercynian transgression-regression cycle. This paper has a discussion on tectonic setting, stratigraphy and paleogeography in the studied area in Devonian Period.
