The Luanchuan ore district located in the southern margin of the North China Craton is one of the most important polymetallic ore district of China, many porphyry-skarn molybdenum deposits, skarn polymetallic pyrite deposits and hydrothermal silver-leadznic vein deposits have been discovered. In recent years, with the Geological Survey Work, the Huoshenmiao skarn molybdenum deposit was discovered in the west of the ore district showing that it has a huge potential for prospecting. However the degree of study of Huoshenmiao molybdenum deposit is very low, the previous studies mainly focused on deposit geology and the Huoshenmiao intrusion (Xu et al.,1989; He et al.,2013), and some problems are still lack of research including the mineralization age and the relationships with NannihuSandaozhuang and Shangfanggou molybdenum deposits. In this paper, based on the deposit geology, six molybdenite samples were selected for precise Re-Os dating, aims to determine the mineralization age and clarify the relationships wih Nannihu-Sandaozhuang and Shangfanggou molybdenum deposits, providing the theoretical basis for searching for mineral resources in the west of the ore district.
