Since ancient times, it has been noted for its abundant trove of mammal fossils, as the hilly area in the vicinity is at the end of a dismembered branch of the Taihang Mountains, where they meet the North China Plain. There are a lot of well-developed and well-preserved Pleistocene sediments with valuable fossilized records in this area. Its great value for the study of human ancestry was first discovered by Western scholars in 1921.展开更多

Here we report new magnetostrati- graphic results that constrain age of the Hougou Paleolithic site in this basin. Magnetite and hematite were identified as carriers of the characteristic remanent magnetizations, with the former being dominant. Magnetic polarity stratigraphy shows that the Hougou sequence recorded the very late Matuyama reverse chron and the Brunhes normal chron. The age of the Hougou Paleolithic site was estimated to be 395 ka based on an averaged rate of sediment accumulation. The combination of our mag- netostratigraphy and previously published chronological data for early Paleolithic or human sites in the high-latitude northern China may document a persistent colonization of the hostile high-latitude areas of the eastern Old World during the mid- die-early Pleistocene.展开更多
