西峡县竹园铜矿脉赋存于含矿构造破碎带中,寨根北韧性剪切带区域性构造控制了铜矿床(点)和化探异常的分布。铜矿体受到破碎带控制,破碎带产状变化处,特别是由陡变缓处往往为铜矿化最富集的部位。区内成矿作用主要表现为构造-流体成矿,成矿方式以充填作用为主,成矿流体在长期构造活动过程中,在破碎带裂隙、角砾间沉淀形成脉状矿体。根据矿物共生组合特征,其矿床成因类型应属中温热液矿床。
西峽縣竹園銅礦脈賦存于含礦構造破碎帶中,寨根北韌性剪切帶區域性構造控製瞭銅礦床(點)和化探異常的分佈。銅礦體受到破碎帶控製,破碎帶產狀變化處,特彆是由陡變緩處往往為銅礦化最富集的部位。區內成礦作用主要錶現為構造-流體成礦,成礦方式以充填作用為主,成礦流體在長期構造活動過程中,在破碎帶裂隙、角礫間沉澱形成脈狀礦體。根據礦物共生組閤特徵,其礦床成因類型應屬中溫熱液礦床。
