一、前言矿脉常件生有很多支矿脉,这些支矿脉的方向及形态也往往是多样的,有时还会分出更次一級的細小支矿脉。所以,在很多脉状矿床中就呈現出一幅錯綜复杂的景象。显而易見,查清这些支矿脉的来龙去脉,掌握它們的規律性,对了解成矿裂隙的成因、成矿构造发展特征以及生产实际工作都有着不可忽視的作用。本文拟就若干类型支矿脉排列的 I. INTRODUCTION The veins often have a lot of veins, and the direction and shape of these veins are often varied. Sometimes, more branches and veins are branched out. Therefore, in many vein deposits presents a complex picture. Obviously, finding out the ins and outs of these vein veins and grasping their regularity have an important role in understanding the genesis of the fracture fissures, the development characteristics of metallogenetic structures and the practical work of production. This article plans to arrange several types of veins
