DOI: 10.13232/j.cnki.jnju.2014.05.002, PP. 538-552
Keywords: 沉积相,δ13c,c/n,沉积模式,相对海平面,南黄海大北槽东沙
Abstract:
根据南黄海辐射沙脊群大北槽东沙07sr03钻孔的沉积相及沉积物中的δ13c和c/n特征，来研究晚更新世以来大北槽东沙地区海平面波动和沉积模式。07sr03孔ams14c测年得到钻孔年龄自深到浅处于41420±615~5630±5014cyrb.p.。沉积相中主要以砂，粉砂和黏土为主，以粉砂居多。沉积物的δ13c处于-26.504‰~-21.812‰之间，c/n为0.045~64.156，表现出大北槽东沙地区的晚更新世以来陆海交互作用显著，在07sr03孔的18~20m和55.6~70m均出现了δ13c高值区，认为是陆地c4植物的有机质沉积影响，与冰期海退情况相符。研究南黄海大北槽区域晚更新世以来的海平面波动变化，40kab.p.以来海侵海退交替，20kab.p.左右迎来末次盛冰期，海平面降至-100m左右，之后气候回暖，海平面逐渐升高，12kab.p.新仙女木期间小幅度海退，随后进入全新世海侵时期，经过海平面迅速升高后，海平面缓慢下降并趋于稳定。综合07sr03钻孔沉积相信息和有机质地球化学指标δ13c和c/n，将大北槽东沙晚更新世以来自下而上的沉积分为河流相→潮滩相→陆地硬粘土相→潮滩相→滨岸相→近代潮流沙脊相的沉积模式。
