| 摘 要： | 桐木沟锌矿床产于秦岭泥盆系多金属成矿带中,在其层状矿体的底板整合地发育一种主要由钠长石和方解石组成的岩石——方解钠长石岩。本文通过对方解钠长石岩的地质特征和地球化学特征的研究,认为其属热水沉积成因,是热水沉积成矿作用的早期产物。

| Abstract: | The Tongmugou zinc deposits are located at the Devonian polymetallic belt in the Qinling range, Calcite albitite, which is composed mainly of albite and calcite, is found concordant beneath the bedded ore body, The geological and geochemical characteristics of the rock indicate that it was formed through hydrothermal deposition, and was the early production of the hydrothermal sedimentary mineralization. |
