| 摘 要： | “双王式”含金钠长角砾岩带有三大成因问题：1．钠长石岩的成因；2角砾岩的成因；3．含金热液胶结物（脉）的成因。本文通过钠长石老多存在角砾化的现象，提出了“钠长石化─岩石体积收缩形成角砾岩”的初步认识，能够较好地解释一些主要地质特征。鉴于这一认识所积累的材料和研究手段还很有限，仅希望赶到抛砖引玉的作用，在一定范围内引起专家们对本类型金矿研究的重视。

| Abstract: | There are three genesis problems in "Shuang Wang pattern", an albite-breccla belt with gold, which are the genesis of albite, breccia and the hydrothermal cement (vein) with gold. On the basis of the phenonmenon of albite with brecciation, it is suggested that the breccia was formed through albite and rock volume contraction, which can explain some important geological characteristics. |
