【摘要】 对界河金矿黄铁矿光片浸蚀实验及导型结构的研究，发现第三成矿阶段黄铁矿具环带结构，由中心到边部都为N导型，热电系数的绝对值连续降低，可分为四个亚阶段，每个亚阶段的物质成分是连续变化的。更多还原

【Abstract】 Erosive experiments and conduct-type studies of pyrite sections from the Jiehe gold deposit re-vealed a zoning structure of pyrite. All the crystals are of N type and the absolute values tend to decrease from the center to the rim. The third stage can be divided into four substages. And the chemical composition shows a continuous change in each of the substage.更多还原
