The anomalies of Pt and Pd in stream sediment in Longchang area, western Guizhou Province are considered as objects of study, and seven couples of compatibility elements (Cr/Ni, Nb/Ta, Pd/Pt, Rb/Cs, Sr/Ba, Th/U and Zr/Hf) and CaO, TFe2O3 are selected as indicators of geochemical trace.
以贵州龙场地区水系沉积物中的Pt、Pd异常为研究对象,选择相容性接近的7对元素比值Cr/Ni、Nb/Ta、Pd/Pt、Rb/Cs、Sr/Ba、Th/U和Zr/Hf以及CaO、TFe2O3作为地球化学示踪指标,对龙场地区水系沉积物的物质来源组成进行了示踪探讨。

Based on the reconstruction for the sequence of multi-episodic fluid rechargings and geological and geochemical traces of fluid source for each stage\'s fluid,especially the key fluid,it is necessary to determine whether the fluid infillings in strata overlying on seals are from ancient oil and gas reservoirs or whether there are meteoric water to recharge in the ancient hydrocarbon reservoirs.
利用古流体对保存条件进行动态评价,是在建立流体活动事件序列的基础上,对每一期流体尤其是那些关键性流体进行地质与地球化学示踪,确定古油气藏盖层以上的地层中是否有来自于古油藏或古气藏中的流体,或者储层中是否有大气淡水的注入,从而就盖层对流体的封盖能力进行评价。
