摘　　要：桦树沟铁Ⅷ矿体处于桦树沟铁矿铁Ⅰ矿体和铁Ⅱ矿体主向斜的北部,独立于其它矿体之外。通过找矿研究及验证,在拟设定研究区范围内,铁Ⅷ矿体在走向方向上西延,有与铁Ⅴ矿体相连之趋势。探矿工程控制铁Ⅷ矿体长310 m,厚14.47 m,深224 m。居铁Ⅰ矿体之下之铁Ⅷ矿体,走向趋势和倾向趋势与铁Ⅰ矿体十分相似,有可能铁Ⅰ矿体和铁Ⅷ矿体“双层成矿”,即铁Ⅰ矿体为上层矿体,铁Ⅷ矿体为下层矿体。铁Ⅰ矿体、铁Ⅴ矿体和铁Ⅷ矿体三者的关系,仍需开展探矿研究和地质勘查验证。Huashugou FeⅧorebody is located in the northern part of the main syncline of FeⅠand FeⅡorebodies in Huashugou Iron Mine,independent of other orebodies.Through prospecting research andverification,in the proposed research area,the FeⅧore body extends westward in the direction of strike,and has a tendency to connect with the FeⅤore body.Exploration engineering control FeⅧore body 310 m long,14.47 m thick,224 m deep.The FeⅧorebody located under the FeⅠorebody,the trend and tendency are very similar to the FeⅠorebody,it is possible that the FeⅠorebody and FeⅧorebody"double mineralization",that is,the FeⅠorebody is the upper orebody,and the FeⅧorebody is the lower orebody.The relationship between FeⅠore body,FeⅤore body and FeⅧore body still needs to carry out exploration research and geological exploration verification.
