中国秦岭地区卡林型金矿成矿模式

The Metallogenic Model on theCarlin-Type Gold Deposits in Qinling of China

（１）中国秦岭地区卡林型金矿床在区域上的分布严格受印支－燕山期构造－岩浆带控制，区域上与Ｈｇ、Ｓｂ、Ａｓ矿密切共生；（２）主要赋矿地层为泥盆系，成矿时代２１４×１０６～１４２×１０６ａ；（３）主要容矿岩石为浅变质细碎屑岩，钠长碳酸盐角砾岩及碳硅泥质岩；（４）成矿物质（Ａｕ）主体来自深部；（５）成矿流体为岩浆热浪（主体）＋建造水＋大气降水组成的混合热液，成矿环境为中低温浅成环境；（６）依矿床形成深度和物理化学条件等差异，将其划分为深部带型、中部带型和浅部带型三亚类。

In areas, the deposits are strictly controlled by structures and magmatic rock zones of Indo-Chinese - Yenshan epoch, and closely association of An with Hg, Sb, As. (2 ) The host-strate is Devonians system and with metallogenetic epoch of 214 ×106～142×106a. (3) The ore-bearing rock are mainly fine elastic rocks, breccia of albite-carbonate and carbonaceous- siliceous argillaceous rock.(4) The ore-forming metal is from the deep of earth crust. (5) The ore-forming solution consists of mixed hydrothermal solution including of magmatic hydorthermal (main) + formation-water + air- water and the environment of ore-forming is low-medium temperature. (6) According to the ore-forming depth and condition of physical-chemical, these deposits may be classified into three class: deep-zone type, mesozone type and epizone type.
