Abstract: Meigou and Weidipo Paleolithic localities are situated respectively near Xishuidi and Hutouliang Villages in the central part of the Nihewan Basin，Yangyuan County，HebeiProvince．The cultural remains lie in the second terrace of the Sangganhe River．Both of the sections include two major parts of cultural remains．The upper is the Hutouliang mierolithie cultural layer．From the lower part of the two localities a total of 57 stone artifacts analyze din this report were unearth edduring the tentative excavation in 1998 and 1999．They were buried above the bottom gravel layers of the tarrace．Based on geomorphology an d relative dating results，the ag e ofthe artifactsshould be estimated to range from 18 to 14Ka BP，i．e．thelate UpperPleistocene．
Among the seven kinds of raw material utilized at the localities chert is the main one for producingtools，and vein quartz plays an important role．Agatetuf and quartzite，etc．werealsoused． The implementsare mostly side-scrapers ．Th e general featuers oftheseartifactsshow thatthey beara strong resemblance to those of Locality Xibaimaying．Furthermore，no microlithic technique factors were found among the sediscoveries．Thus it is considered that they belong to the traditional small flake tool industry in North China and are different from those ofthe micro blade one．
Though the two kinds ofcultural layers namely microblade and smallflake．Tool industries lie together in the same section at Meigouand Weidipo localitie sand are dated to the approximate period， the technological difference between them is notable．It is supposed that the future excavati on and further study of this kind of cultural remains may provide new lights on the relationship of the Upper Paleolithic cultures，especially on the origin of the Hutouliang microlithic culture characterized mainly bywedge-shaped microcoresin the Nihewan Basin and North China．
