Abstract:

?中国西北的新生代地貌演化与喜马拉雅-青藏高原隆升过程有密切关系,因而受到学术界的广泛关注.这些信息往往在各类沉积序列中得到保存.本文对西部黄土高原华家岭山地相对平坦部位覆盖的中新世风成红土堆积进行研究.所选剖面(NL-VII)厚134.7m,至少包含110层野外可识别的古土壤,其磁化率地层与秦安地区的QA-I中新世风成红土剖面可以进行详细的旋回对比,指示了NL-VII剖面的年龄为18.7~11.8Ma,与小哺乳动物化石指示的年龄段一致.上述结果进一步证明了中新世风尘堆积广泛分布的特征,同时也表明,包括华家岭山地和秦安等地基岩高地抬升在内的西部黄土高原地貌分异过程发生于中新世早期.山地上保存的基本连续的风尘堆积序列指示了华家岭山地基底在18.7~11.8Ma期间并未经历强烈的构造运动,否则会导致风尘堆积的显著侵蚀.由于该地区紧邻青藏高原东北缘,我们认为,上述风成红土序列指示了中新世约18~12Ma期间是青藏高原东北部构造相对稳定的一个时期.
