摘　　要：近年来,对云山矿田内云山复式岩体与锡矿化的相关研究取得了较为突出的成果,但寻找大型锡多金属矿床一直未取得重大突破。该矿田内锡矿化主要产于云山复式岩体接触带的岩突、岩舌、岩体凹谷及北北东向断裂等部位,形成的矿床类型主要有接触交代型、岩浆热液型和变质热液型。其中,接触交代型与岩浆热液型具有矿体厚度较大、蚀变强、品位较高等特点。目前,云山矿田已发现多处小型锡矿床,其矿体均赋存在岩体接触带和北北东向断裂。该矿田内许多区域具有相似的成矿条件,如果加大地质勘查力度,有望实现找矿突破。In recent years,significant progress has been made in studying the relationship between Yunshan complex rock mass and tin mineralization in Yunshan Mining Field,but major breakthroughs in finding large-scale tin polymetallic deposits have yet to be achieved.Tin mineralization in the mining field primarily occurs in the contact zones of Yunshan complex rock mass,such as rock intrusions,rock tongues,concave valleys of rock mass,and NNE faults.The main types of deposits formed are contact metasomatic type,magmatic hydrothermal type,and metamorphic hydrothermal type.Among these,the contact metasomatic type and magmatic hydrothermal type deposits are characterized by considerable orebody thickness,intense alteration,and high grades.Currently,several small tin deposits have been discovered in the Yunshan Mining Field,with orebodies found in the contact zones of the rock mass and NNE faults.Many areas within the mining field exhibit similar mineralization conditions,suggesting that increased geological exploration efforts could lead to significant breakthroughs in prospecting.
