摘要
本文对贵州普定白岩脚洞遗址中所获的1220件石片进行了分类观察。根据石片背面石皮的保存情况,疤与疤之间的关系,背疤的受力部位与石片台面的关系等特征,可从一个侧面反映出石核的利用率较高。
The present article deals with 1220 pieces of stone flakes found in the cave of Baiy-anjiao. Puding, Guizhou. According to their striking platforms the flakes can be grouped into 11 categories. The cortex platforms predominate over the artificial ones. The latter is composed of 6 categories, i.e. plain, crested, scarred, prepared (only 0.4%), punctiform and linear.
Judging from the scars left by the previous flakes, it seems to the author that in most cases the core had been flaked 1 to 2 or more times before the given flake detached from it. More than half the flakes show that the matrix had been flaked from one or more directions different from the present platform.
From the characteristics of the ventral surface, angle of striking platform, size and shape of the flakes it was deduced that they might be produced by the simple direct percussion and occasionally by the bipolar technique.
411 pieces of flakes had been fashioned into implements. Among the retouch types the reversed retouch (about 40%) predominates over the other types.
