| 摘 要： | 金红石在国民经济中用途广泛,我国每年需要大量进口.山西碾子沟金红石矿床位于五台西段草垛山分岭背斜南翼,金红石矿体赋存于碾子沟上段地层中,矿体产状与地层产状一致,矿体规模、产状和形态严格受岩体控制,矿化是吕梁期热液活动强烈影响的结果,使得金红石叠加富集.矿床含矿岩石主要为阳起透闪岩、绿泥透闪岩等.金红石呈半自形粒状结构,多分布于透闪石矿物之间.采用金红石(TiO2)边界品位1.0%、工业品位1.6%计算,共求得金红石(TiO2)资源/储量163万t,属于大型矿山. |

| Abstract: | Rutile is of wide uses in the national economy,and a great amount of it is imported from overseas each year.Nianzigou rutile deposit is located in Huyu Town,Daixian County,Shaanxi Province.The deposit is situated in the south wing of Caoduoshan anticline and ore bodies is distributed in the upper parts of Nianzigou formation.Occurrence of the ore bodies is similar to that of strata,and scale,occurrence and shape of the ore bodies are controlled by a magmatic body.Rutile mineralization was result of hydrothermal activities in the Luliang period.Ore-bearing rocks in the deposit are mainly actinolite tremolite and chlorite tremolite.Rutile exists as subhedral granular texture,and is mainly distributed between tremolite.Adopted rutile(TiO_2) boundary contents as 1.0 % and the industrial contents as 1.6 %,the total reserves of rutile in the deposit is calculated as 1.63 million tons,which makes the deposit a large mine. |
