摘要/Abstract

摘要： The present study examines material quarrying, utilization, and exploitation strategy with respect to availability, quality and distribution at Donggutuo, a Lower Pleistocene archeological site in the Nihewan Basin of North China. Through identification of the bedrocks in the vicinity, the analysis reveals that raw materials available at the Donggutuo site are mainly chert, dolomicrite, siliceous dolomite, siliceous limestone, tectonic breccia, quartzite and intermediate lava. Related documents and a geological survey of the area demonstrate that the chert was quarried from dolomite within the Gaoyuzhuang Formation of the Mesoproterozoic Changcheng Group, and the quartzite from the Yousuopu Formation of the Archeozoic Qianxi Group, as well as from Jurassic volcanic lava. Fractures formed by tectonic movements of the Yanshan Stage and the Himalaya Stage made it convenient to quarry these materials. It is observed that fragmentary rock pieces were directly collected and quarried from local fracture belts and that this became the principal strategy of raw material exploitation adopted by the Donggutuo toolmakers. In general, raw materials were not efficiently used, and many of them could have been reduced, retouched and used again. Some suggestions are also proposed to improve the understanding of earlyhumans' tool complex in the Nihewan Basin.

Abstract: The purpose of this paper is to discuss the nature of compact bone age-associated changes, so as to provide the evidence of age estimation with bones for forensic medical and anthropological research.
The middle one third of right sixth rib was collected from 86 Chinese males of north China, ranging from 20 to 70 years of age. Decalcified cross-section slides were histomorphometrically examined by using an image analyzer. Histological parameters used in this study included 10 items :total intact osteon area (X1), intact osteon number (X2), average intact osteon area (X3), total Haversian canal area (X4), average Haversian canal area (X5), total fragmentary osteon area (X6), fragmentary osteon number (X7), average fragmentary osteon area (X8), total visible osteocyte number (X9), and total visible osteon density (X10). The results showed that intact osteon number, total Haversian canal area, average Haversian canal area, fragmentary osteon number, total visible osteon density increased with age, the correlation coefficients were 0.896, 0.835, 0.491, 0.748 and 0.906 respectively; and average intact osteon area, average fragmentary osteon area, total visible osteocyte number decreased with age, the correlation coefficients were -0.750, -0.767 and -0.715 respectively; but total intact osteon area and total fragmentary osteon area didn' t change with age significantly (r=-0.005, 0.011). Then the 10 parameters were subjected to multiple stepwise regression analysis to produce an equation: Y =33.545 +0.938X2 +249.144X4 +0.676X7 -769.784X8 -0.004X9, its multiple correlation coefficient and standard error of estimate were 0.954 and 4.14, respectively. When the formula was tested on 30 specimens, 77% of the estimated ages fall within ±5 years of actual ages, and 100% of the estimated ages fall within ±8 years of actual ages. This paper provides a new method of age determination by bone for forensic medicine and anthropology.
