摘要
关于地壳中广泛分布的石英脉体的成因,传统的岩浆演化最终产物的观点,长期以来被广泛接受。以地质观察为依据,提出了硅酸盐去阳离子作用、产生石英脉体的新观点。硅的析出是热液交代途经围岩的结果。这种水-岩作用可有水交代、碳酸盐化、氢交代和碱交代等不同方式,并可发生于热水流体运移的全部过程。
The idea that quartz vein is the last product of magma evolution has been widely accepted for a long time. In this paper we put out a new idea that quartz vein is formed by decation process of silicate. These rocks give off silica may be the result that hydrothermal replaces it’s passing enclosing rocks. The water-rock reaction includes water-replacement,carbonation,hydrogenation and alkali-replacement, etc.They can occur throughout the process of hydrothermal movement.
