Beijing Institute of Cultural Relics and Archaeology,Beijing,China,100009Abstract The sedimentary characteristics and facies ofthe cultural layers in the late Paleolithic period of the late Late－Pleistocene in theWangfujing Oriental Plaza site were studied based on the comparison and analysis of thetypical sedimentation profile of the site and more than 150 stratigraphic data.The paleo－geomorphicsurfaces during the periods of 2.2×104a B.P.were rediscovered.The studysuggests that the ancients must have acted in the sandy islands of alluvial fans,whichwere evolved in relatively steady water flows during the interglacial stage with slightlywarming in the last glacial epoch.

Combined with related rare earth element and trace element geochemistry of Huangshaping granites and ore-bearing skarn, it is concluded in this paper that the age of 154 Ma should represent the metallogenic epoch of the deposit, and that there existed a close relationship between the ore-forming process of the deposit and the granite porphyry, which were both formed during the peak stage of Early Yanshanian large-scale rock-forming and ore-forming activities in South China.

结合黄沙坪岩体及含矿硅卡岩型矿体的稀土及微量元素地球化学特征，得出以下认识：该矿床的成矿年龄在154Ma左右；成矿作用与花岗斑岩关系密切，它们都是华南燕山早期大规模成岩成矿作用高峰期的产物。

The metallogenic epoch of the deposit was indirectly deduced by the ages of such nearby granitic rocks as granite porphyry and quartz porphyry or altered minerals.

Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。
