摘要: 根据闽南粤东沿海的野外调查与室内研究,本文记述了若干地层剖面,公布了22个14C样品的年代测定结果,对晚第四纪地层进行了划分与对比,并对全新世海平面变化与构造运动的特征等问题进行了初步讨论。认为本区自晚第四纪以来属于轻微一中度上升地区。
Abstract: According to the field investigation along the coastal area of South Fujian and East Guangdong and the 14C age determinations, a number of stratigraphical profiles are described and 14C dates of 22 samples published. The subdivision and correlation of the late Quaternary stratigraphy, the Holocene sea level changes and the characteristics of neotectonic movement are preliminarily discussed in this paper.The late Quaternary stratigraphy in this area can be divided into Jiangtian peat and Jingzhou mud belonging to the late Holocene; Zhanglin chenier, Gongqian beachrock and Juewei mud to the Middle Holocene; Xianqian formation of the Early Holocene and Meipu calcareous tufa, Chishan peat, Jiazi buried soil and Houlou formation of the late stage of Late Pleistocene.From the altitudes and C14 dates of marine beds, beachrock, cheniers as well as sedimentological, geomorphological and biological evidences indicative of the positions of paleosea level, the authors come to the conclusions on the lower stands of sea level in the late stage of late Pleistocene, rising of sea level of the Early-Middle Holocene, and existence of several higher sea levels in the past 6000 years than the present-day's, that were further, proved to be correct. Correlation of altitudes and ages 14C of samples of this area with representative curves of the Holocene sea level changes, it can be seen that this area can be ascribed to a gentle to moderate uplift one, denying then the idea on the subsiding coast of the South China. Thereby it is also unfavourable to the view on the intense uplift of this area.
