广西钦州市麻园-睦家锰矿地质特征及成矿模式研究

Research on the Geological Characteristics and Metallogenic Model of the Mayuan-Mujia Manganese in Qinzhou City, Guangxi

广西钦州市麻园-睦家地区位于钦州-防城锰矿带北部,通过收集该地区现有工作成果,结合本次实际勘查工作,总结了矿体地质特征、控矿因素、找矿标志及成矿规律。发现该地区锰矿主要位于泥盆系石梯水库组(D3s)、石炭系石夹组(C1sj)和石炭系-二叠系板城组(C2P2b)含锰岩系中,区内广泛发育的构造控制着矿体形态、产状,影响着矿体的富集与保存,是研究区锰矿重要的控矿因素之一。在此研究基础上建立矿床成矿模式,并提交了钦州市板城镇麻园-睦家找矿靶区1处。

The Muyuan-Mujia area is located in the northern part of the Qinzhou-Fancheng manganese ore belt.By collecting the results of previous work in the area and combining them with the actual survey work,it summarize the geological characteristics of the ore body,ore controlling factors,prospecting sign and metallogenic regularities,and find that the distribution of manganese is mainly located in the Devonian Shiti Reservoir Group(D3s),Carboniferous Shijia Group(C1sj)and Carboniferous-Permian Bancheng Group(C2P2b)manganese-bearing rock systems.The widely developed tectonics in the area control the morphology,production of the ore body and affect the enrichment and preservation of the ore body.It is one of the important controlling factors of manganese ore in this area.On the basis of this study,a mineralization model for the deposit was established and a target area for ore discovery was submitted for the MaYuan-MuJia in Bancheng Town,Qinzhou City.
