【摘要】：更新世期间秦岭南北麓及其腹地的山间盆地中沉积有大面积的黄土,这里的黄土地层不仅记录了更新世以来当地古地理与古环境变迁的过程,而且赋存有丰富的古人类和旧石器文化遗存.秦岭北麓及南洛河中下游地区黄土堆积厚度大,黄土-古土壤地层发育完善,有比较连续的冰期-间冰期尺度上的黄土堆积.秦岭主脊以南各山间盆地黄土堆积厚度不大,颗粒较细,在这种"迷你"型的黄土地层中,人类文化遗存的密度普遍高于秦岭以北的旧石器遗址,有利于考古调查和发掘工作的开展.多年来的古人类和旧石器遗址地层年代学研究结果证实,距今1.15(1.63/1.62?)~0.6Ma期间,秦岭地区的旧石器文化面貌主要以砾石砍砸器、石核、石片和简单修理的石片工具为主,属旧大陆模式I石器工业的范畴.蓝田公王岭和陈家窝、洛南上白川和刘湾、卢氏乔家窑、汉中龙岗寺和窑厂湾、安康关庙(吴台村)以及郧县人等旷野旧石器遗址下部文化层是该类遗存的代表;距今0.4~0.25Ma时段的洛南花石浪龙牙洞遗址则继承了当地前期旷野模式I旧石器遗存的特点,文化面貌主要以石核、石片和刮削器、尖状器、雕刻器等小型石片工具为主;距今250~50ka期间,秦岭地区出现了大量模式Ⅱ(阿舍利类型)石器工业遗存,两面修理的手斧、手镐和薄刃斧等工具普遍发现,说明该地区的石器工业完成了一个重要的转型过程.洛南盆地张豁口、郭塬和槐树坪、蓝田刁寨、甘峪、涝池河和泄湖、汉中何家梁等遗址是该类遗存的代表;到晚更新世晚期与全新世之交,秦岭南北麓可能还存在小石片石器工业类型的遗存.秦岭地区不同阶段的旧石器组合展示了更新世期间人类生活与石器技术行为发展演化的历程.
[Abstract]:During the Pleistocene, a large area of loess was deposited in the southern and northern foothills of Qinling Mountains and the intermountain basins in its hinterland. The loess strata here not only recorded the evolution of the local paleogeography and paleoenvironment since the Pleistocene. And rich in ancient humans and Paleolithic culture remains. In the north foot of Qinling Mountains and the middle and lower reaches of Nanluo River, the loess accumulation thickness is large, the loess-paleosol strata are well developed, and there are relatively continuous loess deposits on the scale of ice-interglacial period. The loess deposits in the intermountain basins south of the main ridge of the Qinling Mountains are of little thickness and fine particles. In this "mini" loess stratum, the density of human cultural remains is generally higher than that of the Paleolithic sites north of the Qinling Mountains. It is conducive to the development of archaeological investigation and excavation. Years of paleo-human and Paleolithic site chronological studies have confirmed that during the period from 1.15 (1.63? 1.62?) to 0.6Ma, the paleolithic cultural features of Qinling area were mainly composed of gravel choppers and stone cores. Slicing and simple repair tools are dominant, belonging to the Old World Model I Stone Industry. Lantian Gong Wang Ling and Chen Jia Wo, Luoshi Qiaojiayao, Longgang Temple and Kiln Factory Bay, Ankang Temple (Wutai Village) and Yunxian people are the representatives of the Paleolithic sites in the wilderness, such as the lower cultural layer of the Paleolithic sites in Luonan, Upper Baichuan and Liu Wan, Lushi Qiaojiayao, Hanzhong Longgang Temple and Kiln Factory Bay, etc. The Luonan Stone Wave Longya Cave site in 0.4~0.25Ma period inherited the characteristics of the Paleolithic relics of the former wilderness mode I, and the cultural features were mainly small stone tools such as stone core, stone slice and scraper, sharp ware, engraver and other small pieces of stone tools, such as stone core, stone slice and scraper, etc., and the main cultural features were the stone core, stone slice and scraper.
