本文对“对《陕西某卡林型金矿床矿石结构特征》一文若干问题的商榷”提出的疑问进行讨论. 1.两种成因的矿物颗粒其形态特征不同。 2.保留凝胶沉淀物的同心环带是黄铁矿复晶的重要形态特征。 3.凝胶沉淀物的干裂纹和凝缩孔隙是识别黄铁矿复晶的一种标志。 4.黄铁矿放射状变晶结构是凝胶再结晶作用的产物。笔者再次确认,陕西某卡林型金矿床中,含金黄铁矿是由凝胶再结晶作用而成的变晶颗粒,不同于由溶液中直接晶出的结晶颗粒。
In this paper, we discuss the questions raised on “Several Issues on Ore Structure Characteristics of a Certain Carlin-type Gold Deposit in Shaanxi Province.” 1. The two types of mineral particles have different morphological characteristics. Concentric rings that retain the gel precipitate are important morphological features of pyrite recrystallization. 3. The dry crack and the condensed pore of the gel precipitate are a sign of identifying pyrite recrystallization. Pyrite radial crystalline structure is the product of gel recrystallization. The author once again confirmed that in a certain Carlin-type gold deposit in Shaanxi Province, the gold-bearing pyrite is a modified crystal grain formed by the gel recrystallization, unlike the crystal grains directly crystallized from the solution.
