摘要
中甲锡多金属矿床是受政和一大埔断裂带的低序级构造所控制的矿床。控矿构造研究表明，锡矿化及矿体主要受NE－NNE、NW向断裂、裂隙以及接触带构造的复合控制，构造变形以服性—脆韧性为主，构造控矿型式多样并决定矿（化）体的空间定位方式，形成高中温热液型、破碎蚀变岩型、斑宕型锡多金属矿床，成为中甲锡多金属矿床的重要成矿地质条件之一。
Zhongjia tin and multimetal deposits are controlled by lower grade structures of Zhenghe-Dapu Fault Belt. Studying on ore-controlling structures indicates that tin mineralization and orebodies are mainly controlled by NE-NNE and NW strike faults and contact zones. The structural deformation features are characterized by brittle and ductile-brittle. Various types of structure-controlling on ore determine the patterns of ore-shoots emplacement, in which forms highand moderate temperature hydrothermal, altered rock and porphyry deposits. Therefore structure is an important metallogenic geology condition in forming tin and multimetal deposits.
