| 摘 要： | 焦家金矿床位于胶东西北部的招掖成矿带内，西临著名的郯庐大断裂。矿体赋存于NNE-NE向延伸的断裂破碎蚀变带中，受控于断裂构造，围岩蚀变以钾长石化（红化）、黄铁绢英岩化、硅化、碳酸盐化为特征。本文运用分形理论研究了I、Ⅱ、Ⅲ号主矿体的品位、厚度、品位厚度乘积的分维值在垂向上的变化特征，根据分维值D的规律性变化，提出该矿床深部三个主要矿体仍有较大延伸。

| Abstract: | Jiaojia Gold Deposit is located in the Zhaoyuan-Yexian gold belt in northwest Shandong Peninsula,which is bordered on the well-known Tancheng-Luzhong fault belt in the west.Gold mineralization was developed in the NNE-and NE-trending altered-fractured zones.The alterations are characterized by K-feldsparization,pyretic-phyllic alteration,silicification,and carbonation.The fractal theory results calculated describes the vertical variation of grade,thickness and grade multiplication thickness in gold minerali... |
