中文摘要：

黑龙江省十八站遗址经过再次调查发掘,地层中出土石制品38件,地表采集20件.石核具有修理台面和对向剥片的技术,石片中石叶技术特征明显,石叶技术与水洞沟遗址相近,石器以轻型为主,主要类型为刮削器.采集的两面器和端刮削器则在华北地区、俄罗斯远东地区南部的几个遗址中有相似标本发现.采用光释光的方法对遗址的绝对年代进行测定,结果为距今2.5-1万年.

英文摘要：

New excavations were carried out at the Shibazhan Paleolithic site in Tahe Country, Heilongjiang Province. This paper describes and analyzes 58 artifacts： 38 pieces of stone were unearthed from B and C layers, and 20 pieces of stone were collected from the ground surface nearby. Blades are important components of this assemblage, which is similar to the Shuidonggou site located at Ningxia Hui Autonomous Region. A bifacial specimen and a round-end scraper collected on the ground exhibit close resemblance to the stone tool types from some microlithic sites in northern China and the far eastern region of Russia. The absolute date of the four layers of this site were dated by optically stimulated luminescence （OSL）, and two cultural stages were established, namely 25 ka BP （Level C） and 10 ka BP （Level B）, respectively. With its location in northeastern China and on the basis of morphological characters of these stone artifacts, the Shibazhan Paleolithic site provides important data for studying northeastern Asian human migration and cultural communication during late Pleistocene and early Holocene.
