山西孙家庄中酸性杂岩体及其邻近地区的找矿远景评价

通过“面型”岩石测量和多子样剖面岩石测量,对山西孙家庄中酸性杂岩体作出找矿远景评价,并对其邻近地段进行矿化追踪。确定该岩体的主要指示元素和伴生元素,圈出以Cu为主的斑岩矿化多元素组合异常,在Cu异常浓集中心发现斑岩矿化。孙家庄岩体周围地区,存在斑岩型矿化—接触交代矿化—热液多金属矿化的环带状分布模式。

EVALUATION OF PROSPECTING POTENTIAL IN SUNJIAZHUANG INTERMEDIATE-ACID COMPLEX BODY AND NEIGHBORING AREAS, SHANXI PROVINCE

Based on “planar” rock survey and “multi daughter sample” sectional rock survey, the authors conducted evaluating of prospecting potential for Sunjiazhuang intermediate acid complex body and made follow-up survey for mineralization in neighboring areas. The main indicator elements and associated elements were determined, and the Cu-dominant multi-element composite anomaly from porphyry mineralizastion was delineated, with porphyry mineralization discovered at the concentration center of the Cu anomaly. Around Sunjiazhuang complex body there exists a zonal distribution pattern of porphyry mineralization contact metasomatic mineralization hydrothermal polymetalic mineralization.
