摘要:

都兰县洪水河铁矿产于蓟县纪狼牙山组中, 是一套以浅变质的镁质碳酸盐岩、碳酸盐岩组合为主, 夹细碎屑岩的地层。区内岩浆岩发育, 岩浆作用具有多期次活动的特点, 为各类矿床的形成提供了极为有利的条件。断裂和褶皱构造极为发育。断裂构造主要受北部昆北和南部昆中深大断裂的影响, 主干断裂总体呈NW-NWW 或近ES 走向多条断裂平行排列, 以逆断层为主, 控制了地层展布方向和岩浆岩的分布, 是区域控矿构造; 其次为NE-NNE向次级断裂, 对矿体具破坏作用。矿床成因属沉积变质型铁矿床。

Abstract:

Hongshuihe iron ore in Dulan county is located in Langyashan qroup of Ji county period, it is a set of shallow metamorphic strata formed by magnesian carbonate rock, constitution of carbonate rock and some fine grained clastic. There are more magma, and the magmatism has the characteristics of many activities, this has given an extremely favorable condition for the formation of various types of deposits. The faults and folds construction have great development. The fault have been mainly impacted by the Northen kunlun deep and great faults in north and the mid kunlun fault in south, the main faults show NW-NWW or nearly ES strike multiple fratures parallel arrangement and mainly reverse faults, they control the distribution of layer direction and magma, and also be the regional ore-controlling structure. NE-NNE strike are the secondary faults, they have damage effects for ore body. The genetic type of deposit is the sedimentary metamorphic iron deposit.

Key words: Hongshuihe iron ore, Geological characteristics, Genesis of deposit, Dulan county, Qinghai
