【摘要】：2009~2012年,在秦岭南麓汉水上游汉中盆地梁山周围新发现何家梁和窑厂湾2处旷野类型旧石器地点,采集石制品252件。早期人类加工石制品的原料来自于河流堆积物中的石英、火山岩、石英岩、硅质灰岩和砂岩等砾石,采取硬锤直接打击法和砸击法剥片。石制品种类包含石锤、石核、石片、修理的工具和断块。工具类型以砍砸器、石球、重型刮削器、手斧和手镐等重型器物为主。汉中盆地梁山周围以龙岗寺等地点为代表的旧石器地点群是含阿舍利(Acheulian)类型器物的石器工业。何家梁和窑厂湾地点分别位于汉江右岸第二和第三级阶地上,通过对窑厂湾地点黄土地层剖面进行回授光释光(TTOSL)方法测年,结合古地磁测试和对比黄土高原标准黄土地层序列测年结果,证实汉中盆地古人类活动的时代最晚在60万年前就已经开始,而何家梁地点的地层测年数据则表明距今7、8万年左右存在另外一个古人类活动繁盛的阶段,早期人类在汉中盆地活动有较长的时间跨度。以前汉中盆地发现的旧石器地点没有独立的年代数据,极大地限制了学术界对其石器工业技术和人类行为的深入研究,这是首次获得的汉中盆地埋藏旧石器地点地层的独立年代数据,是对汉中盆地旧石器遗址年代学认识上的一大突破。本研究结合可靠的测年数据,分析石器组合及加工技术,对建立中更新世以来秦岭山区的旧石器文化序列,理解我国南北方旧石器工业的发展演化以及东西方旧石器工业技术比较具有重要的参考价值。
[Abstract]:2009~2012, in the new found around Liangshan south of Qinling Mountains upper Hanzhoung basin hejialiang and kiln bay 2 wilderness type Paleolithic sites, collecting 252 pieces of stone products. Early human processing of stone products raw materials from the river sediments in the volcano rocks, quartz, quartzite, siliceous limestone and sandstone gravel. Take a direct hit hard hammer and hammer stripping method. Stone product categories include stone hammer, stone, stone, repair tools and tools to block. Types of choppers, stone ball, heavy-duty scrapers, axe and hand picks and other heavy artifacts. Around the Hanzhoung basin in Liangshan Longgang Temple site as the representative of the Paleolithic site group is Ashley containing (Acheulian) type of artifacts. Stone industry hejialiang and kiln bay sites were located in Hanjiang River right bank second and third terraces, release light through the feedback of kiln bay sites of loess strata section light (TTOSL) The method combined with the paleomagnetic dating, Loess Plateau and loess test comparison standard stratigraphic sequence dating results, confirmed that the Hanzhoung basin of ancient human activity era in the late 600 thousand years ago, while the hejialiang location stratigraphic dating data indicates that there are about 7,8 million years ago another prosperous ancient human activity early stage, human beings have a longer time span in the Hanzhoung basin. The previous Hanzhoung basin found in Paleolithic sites without independent data, greatly limits the academic circles the in-depth study of stone industry technology and human behavior, which is independent of age data buried Palaeolithic site formation in Hanzhoung basin is obtained for the first time. The chronology of Hanzhoung basin Paleolithic sites on the understanding of a major breakthrough. On the basis of data analysis and combination of reliable, stone processing technology, the establishment of the Middle Pleistocene to the Qin Dynasty The sequence of Palaeolithic culture in Ling mountain area has important reference value for understanding the development and evolution of the north and South China's Paleolithic industry as well as the comparison of eastern and Western Paleolithic industry technology.

【正文快照】： 1引言汉中盆地位于秦岭南麓,是汉水上游最大的新生代断陷性盆地,这里也是我国秦岭以南发现旧石器地点比较集中的地区之一。早在上世纪50年代,汉中盆地梁山脚下的龙岗寺一带便有旧石器发现的报道,但囿于当时认识的局限性,报道语焉不详。汉中盆地旧石器被广泛注意是上世纪80年
