【摘要】 <正> 一、序言台湾海峡西岸的第四纪地质工作,解放前,只是在地质矿产调查,土壤调查时涉及到一些。而第四纪有孔虫的研究工作更是空白。解放后,特别是近几年来,伴随着福建省水文地质,工程地质等工作的开展,积累了相当数量的钻孔和地表资料,出现了系统地研究第四纪地质的新局面。1977—1980年,我们与福建省水文工程地质队协作,对福建沿海一些钻孔中的有孔虫等化石,进行了分析研究。本文主要根据五个钻孔(图1)岩心中的有孔虫、硅藻等化石群特征,参考有关资料,就台湾海峡西岸的福州盆地、闽江口和厦门筼筜港地区的第四纪地层的划分、第四纪海侵层的沉积环境和第四纪地层发育史,进行初步研究。更多还原

【Abstract】 Five cores from the west coast of the Taiwan Strait were analyzed for their biotic components and biofossils such as diatom are found in all the cores. 28 genra, 55 species of benthonic foraminifera are found in the cores of Langqi from Minjiang River, Guangtou from the northern bank of Minjiang River and Yuandang Harbor in Xiamen. Marine biofossils are only found in middle Holocene Series deposits. The core in Yuandang Harbor reflects the deposit of Upper Holocene Series. There are only late Pleistocene and Holocene deposits in Cenozoic due to the structural uplifting, and a layer of sea invasion is only found in the deposits of Holocene Epoch.更多还原
