含金化学沉积岩中的氧同位素关系与富金化学沉积岩有关的基本问题是矿化热液流体的来源、温度以及该流体排出时与水圈平衡的范围。为解决这些问题,测定了某些太古代金矿含金化学沉积岩内和包于主围岩中纯燧石(SiO>90％)的氧同位素组成。沉积岩部分的最大δ值见表5。这些数据提供了水圈的同位素和热演化的关系。因此,首先拟恰如其份的概述测定海洋燧石的δ~(18)O的参数,然后将其结果在这里加以讨论。
Oxygen isotope relationships in gold-bearing chemical sedimentary rocks The basic problems associated with gold-rich chemical sedimentary rocks are the source and temperature of the mineralized hydrothermal fluids and the range of equilibrium with the hydrosphere upon discharge of the fluid. In order to solve these problems, the oxygen isotopic composition of some chert chests (SiO> 90%) in the gold-bearing chemical sedimentary rocks of some Archean gold deposits and in the main surrounding rocks was determined. Sediment part of the maximum δ value in Table 5. These data provide the relationship between isotopes and thermal evolution of the hydrosphere. Therefore, first of all, a suitable outline of the δ 18 O parameters of marine flint should be determined and the results will be discussed here.
