中文摘要:山西中条山地区是中国华北中部造山带金铜多金属成矿带的重要组成部分。最近，文章在中条山东北段垣曲县一带新发现多处斑岩型金矿（化）体。通过专项地质填图及物化探异常圈定，经钻探验证，文章发现金矿化体28 处，累计视厚度131.96 m，w(Au)为0.1~0.88 g/t；金矿体17 处，累计视厚度34 m，w(Au)为0.3~0.88 g/t。本次工作首次在中条山东北段花园沟地区发现与早白垩世岩浆活动有关的斑岩型金矿（化）体，表明中条山地区具有寻找燕山期板内岩浆活动有关的斑岩型金多金属矿床的巨大潜力，为区内寻找金多金属矿床开辟了新方向。

Abstract:The Zhongtiao Mountains region is an important component of the polymetallic metallogenetic belt of the Trans-North China orogen. Recently, supported by the new round of the Mineral Exploration Breakthrough Strategy Action Project, the project team discovered several porphyry gold mineralization occurrences in Yuanqu County of the Northeast part of Zhongtiao Mountains region, Shanxi. So far, according recent drilling programs, 28 Au mineralized bodies (with cumulative apparent thickness of 131.96 m, w(Au) ranging from 0.1 g/t to 0.88 g/t) and 17 Au ore bodies (with cumulative apparent thickness of 34 m, w(Au) ranging from 0.3 to 0.88 g/t) have been identified. For the first time, this work has exposed porphyry gold ore bodies related to Early Cretaceous magmatic activity in the Huayuangou area of the northeastern Zhongtiao Mountains region. This indicates that the Zhongtiao Mountains region holds great potential for exploring porphyry gold-polymetallic deposits associated with Yanshanian intraplate magmatic activity, opening up new directions for the exploration of porphyry gold-polymetallic deposits in the region.
