本文对《陕西某卡林型金矿床矿石结构特征》一文提出三点疑问进行讨论。 1.对黄铁矿颗粒属于由凝胶再结晶作用形成的“变晶”的置疑与商榷。 2.对“黄铁矿颗粒中常残留有原凝胶沉淀物特有的干裂纹和星状孔隙”的讨论。 3.对“细粒黄铁矿放射状变晶结构”的置疑。笔者认为含金黄铁矿的内部环带结构和环(累)带构造是本矿床重要的结构特征,它分布广泛,显示的组构特征复杂,系由含矿热水溶液中直接结晶出来的。把这种黄铁矿看作是由凝胶再结晶作用形成的“变晶”是不妥的。
This article discusses three questions raised by the article “Ore structure characteristics of a Carlin-type gold deposit in Shaanxi Province.” 1. Questioning and discussing “pyrite” formed by pyrite recrystallization on pyrite particles. 2. Discussion on “Dry crack and star-shaped pores peculiar to the original gel sediment in pyrite particles”. 3. The “fine-grained pyrite radial crystalline structure,” the doubt. The authors believe that the internal ring structure and ring (tired) belt structure of gold-bearing pyrite is an important structural feature of the deposit, it is widely distributed, showing the complex structural features, crystallized directly from the ore-bearing hot water solution. It is improper to think of this pyrite as a “metamorphic” formed by the recrystallization of the gel.
