红龙厂铜矿是元江铜矿区的重要金属矿床之一，大地构造位置在川滇台背斜的红河深
大断裂北东侧。基于以往的研究成果，结合矿区近年勘查研究新进展，通过梳理区域成矿背景、矿区
地质特征，在矿床成矿规律方面取得新认识。研究表明：区域昆阳群变质岩系及复杂的构造格局提
供了极为有利的成矿背景条件；红龙厂铜矿具有严格的层控性，矿体主要赋存于落雪组二段乳白色
白云岩或上覆青灰色白云岩底部；矿区青扬大断裂的次级褶皱及次级断层控制着地层和矿（化）的分
布，为成矿提供了热动力条件和赋存空间；矿床主要形成于氧化-还原环境中，矿质主要积聚于弱还原
环境的低洼地带，属于典型的沉积-变质-改造层状铜矿床；矿区赋矿层位、构造活动强烈部位等可作
为重要的找矿标志，下一步应加强对F3断层下盘及主矿体北东段深边部的地质找矿工作。
Honglongchang copper deposit is one of the important metal deposits in Yuanjiang copper
deposit area. The geotectonic location is located on the northeast side of the Honghe deep fault in the Sich⁃
uan-Yunnan platform anticline.Based on the previous research results，combined with the new progress of
exploration and research in the mining area in recent years，by combing the regional metallogenic back⁃
ground and geological characteristics of the mining area，in order to obtain new understanding in the metallo⁃
genic regularity of the deposit.The research shows that the metamorphic rock series and complex structural
pattern of the regional Kunyang group provide extremely favorable metallogenic background conditions.The
Honglongchang copper deposit is strictly stratabound. The ore bodies mainly occur at the bottom of the milky
dolomite or overlying gray dolomite in the second member of the Luoxue Formation.The secondary folds and
secondary faults of the Qingyang fault in the mining area control the distribution of strata and mineralization，
providing thermal dynamic conditions and occurrence space for mineralization.The deposit is mainly formed
in the oxidation-reduction environment，and the minerals are mainly accumulated in the low-lying areas of
the weak reduction environment，which belongs to the typical sedimentary-metamorphic-modified layered
copper deposit.The ore-bearing strata and strong tectonic activities in the mining area can be used as impor⁃
tant prospecting indicators. The next step should be to strengthen the geological prospecting work on the foot⁃
wall of the F3 fault and the deep edge of the northeast section of the main ore body.
