摘　　要：丹江口水库库区位于湖北、河南和陕西三省交界处,处在我国地势第二级阶梯的东缘,是汉水上游到中游的过渡地带,汉水由西向东、丹江由北向南在此汇合,西南、西北和东北分别环绕武当山、秦岭和伏牛山,东南与江汉平原相接。丹江口水库淹没区地质构造复杂,发育了变质火山碎屑岩、硅质灰岩、片岩、千枚岩、砂砾岩、砂岩、泥岩等。汉水形成于第三纪后期.Salvage excavations of Area A at Maling location No.2 conducted by the School of History,Renmin University of China,the Institute of Vertebrate Paleontology and Paleoanthropology,Chinese Academy of Sciences,and the School of History and Culture,Hebei Normal University from April to May 201l revealed an area of 300 square meters and unearthed 986 stone artifacts,which were buried in the clay layer of the third basement terrace on the right bank of the Danjiang River.Stone artifacts include cores,flakes,hammers,bifaces,chopper-cores,scraper-cores,etc.Raw materials,predominated by quartzite,mainly consist of rounded gravel selected by ancient people from the riverbed and gravel layer at the base of the terrace.Direct hard hammer percussion was the principal flaking and retouching technique.Stone blanks of relatively large size were the main processed objects.Bifaces were produced through a relatively consistent system.The lithic assemblage bears resemblance to Acheulean technology.The site comprises secondary alluvial deposits formed by a NW-SE directional flow.OSL dating suggests that the site dates to 390,000-220,000 BP,or the late Middle Pleistocene.
