Abstract:

The Devonian strata in the northern Guangdong Province are widely distributed and well-developed,with abundant fossil data. Through comprehensive stratigraphic comparisons and analyses of lithostratigraphy,biostratigraphy,sequence stratigraphy and event stratigraphy in the research area,and based on a measured section in the Nangang Village,Liannan County(four sedimentary facies,three biological zones and eight stratigraphic sequences),three distinct evolutionary stages of Devonian sedimentary paleogeography are recovered(Middle Devonian Givetian,Late Devonian Frasnian and Famennian). Under the opening and expansion of the Qinfang Trough,the northern Guangdong Province was gradually transgressed,forming a platform basin intertwined with a trough basin. It reached the largest ocean basin in the late Frasnian stage,and began to gradually recede during the Famennian stage. The paleogeographic feature affected the paleontological distribution and spatiotemporal migration,such that the transition from the coral-stromatoporoid reef community(Givetian),stromatoporoid reef community(Frasnian)and fungal-algae reef community(Famennian)was clear in the Nangang Village,Liannan County. According to Devonian regional paleogeographical characteristics,reef communities,tectonic and climatic background,the tectonic event was the dominant factor for the biological and geological environment,especially during the Late Devonian F-F event.

摘要:

华南粤北地区泥盆系分布广泛,化石资料丰富,地层发育齐全。通过对该区域岩石地层、生物地层、层序地层和事件地层的综合地层对比,结合粤北连南实测剖面4个沉积相带、3个生物带和8个三级层序的控制,恢复了粤北地区中泥盆世吉维特期、晚泥盆世弗拉期和法门期3个阶段的沉积古地理演化。结果表明,伴随着钦防海槽的打开和扩张,从中泥盆世吉维特期开始粤北地区逐步海侵,形成台盆-台沟交互的洋盆格局,至弗拉期晚期海侵达到最大,自法门期开始逐步海退。该古地理面貌影响了生物礁的分布和时空迁移,在粤北连南地区表现为珊瑚-层孔虫生物礁(吉维特期)→层孔虫生物礁(弗拉期)→菌藻类生物礁(法门期)的变迁。综合分析粤北地区泥盆纪的沉积古地理演化、生物(礁)群落、构造和气候背景,认为构造因素是该地区泥盆纪生物事件与地质环境变化的主控因素,尤其是晚泥盆世F-F事件。
