【摘要】 前湖剖面第四系出露比较完整，层次清晰，发育有炭质层、铁盘、重矿砂砾石层、“老红砂”层和玄武岩等特殊地层，是一个研究闽南沿海第四纪地质问题的比较有代表性的地表露头剖面。本文通过对前湖剖面中系列样品进行测年、微古、孢粉、矿物、粒度等综合分析研究，探讨了闽南沿海晚更新世晚期以来的古气候变化、海平面变动、“老红砂”的形成年代及成因以及第四纪地层划分等问题。更多还原

【Abstract】 The Quaternary strata, outcrop quite completely and clearly in Qianhu Section, containsome special strata such as the carbon sediment, the iron hardpan, the heavy mineral sandygravel layer, the＂Old Red Sand＂ and the basalt. It is a typical outcrop to study the Quater-nary geologic questions along the coast of southern Fujian. By a comprehensive analysis ofdatinges, microfossil, sporo-pollen assemblages, mineral composition and granulorpetric fea-tures of a series of samples from this section, the questions about the palaeoclimate and thesea-level changes since the Late Pleistocene, the geologic age and the formation of the ＂OldRed Sand＂ and the Quaternary stratigraphic division along the coast of southern Fujian havebeen discussed in this paper.更多还原
