摘　　要：山东巨野核桃园地区是鲁西南地区沉积变质型铁矿床的成矿有利靶区,利用地面高精度磁测对该地区航磁异常进行查证,圈定了磁异常区4处,选取其中1个异常区进行钻探验证,首次在山东巨野地区发现沉积变质型铁矿床,地质找矿工作取得突破性进展,同时为下一步勘查工作奠定了基础,验测结果表明,李登楼—考庄一带找矿靶区成为今后巨野核桃园地区铁矿勘查工作的首选区域。Hetaoyuan area in Juye county in Shandong province is the main metallogenic area of sedimentary metamorphic iron deposits in the southwest of Shandong province.The aeromagnetic anomalies in this area have been verified by using high precision magnetic survey on the ground,four magnetic abnormal areas have been circled,and one area has been chosed for drilling verification.The sedimentary metamorphic iron deposits are first discovered in Juye area in the east of Shandong province.Geological prospecting work has made a breakthrough and laid a foundation for the next exploration work.The prospecting target area in Lidenglou-Kaozhuang area will become the first choice for iron ore exploration in Hetaoyuan area in Juye county in the future.
