河南舞钢铁矿地质特征及深部找矿研究

Study on the Geological Characteristics and Deep Prospecting of Iron Deposits in Wugang City,Henan Province

通过对矿体地质特征、成矿地质条件及物探磁异常的分析研究,达到指导矿产勘查工作并预测找矿方向的目的;通过分析研究区内构造特征、地层对比及物探磁异常,指出研究区处在马超营断裂以北的俯冲带上,在F6断裂的作用下,地层发生自南向北、自下而上的推动作用,使含矿地层由深到浅运移。区内存在赵案庄群和铁山庙组2个含矿层位,并构成"赵案庄型"和"铁山庙型"2种铁矿类型。研究认为矿床的形成与火山喷发密切相关,是在地表水作用下经过分选沉积而成。根据矿床成因特点,指出舞阳铁矿成为特大型矿床的成矿偏在性,认为该区带在深部有较大的找矿潜力。为配合目前的地质找矿工作,对找矿有利区段和资源量进行了预测。

Based on the orebody geological characteristics,geological conditions and geophysical magnetic anomalies analysis,this paper achieved the purpose of guiding mineral exploration work and predicted the prospecting direction.Through the analysis of structural characteristics,stratigraphic correlation,and geophysical magnetic anomalies in the region,pointed out the study area is located in the ubduction zone in north of Machaoying fault.The promotion taked place in the stratum from south to north and from low to up,which promoted the ore-fearing stratum from deep to shallow.There exists two ore-fearing stratum,Zhaoanzhuang Group and Tieshanmiao Group,and formed two rion deposit types,Zhaoanzhuang type and Tieshanmiao type.Deposit formation is closely related to the volcanic eruption,and is deposited in the role of surface water after sorting.According to the characteristics,proposed that Wuyang Iron Ore mineralization is one of large deposits of partial resistance,which has great potential for the prospecting in the deep.To the current geological prospecting,predicted the amount of resources in this area.
