招平断裂带中段构造原生晕地球化学特征及找矿模型

Geochemical Characteristics and Prospecting Model of Tectonic Primary Halos in the Middle Section of Zhaoping Fault Zone

摘要:

招平断裂带是胶西北地区重要的金矿成矿带，该带上已发现多个特大型、大型、中型金矿床，金矿床的成矿具有多期、多阶段叠加的特点。该文对招平断裂带中段深部构造地球化学特征进行了研究，成矿元素异常组合为Au，Ag，Cu，Pb，Zn，As，Sb，Bi，B，Hg，Mo，As，Sb，Hg为头晕指示元素；W，Bi，Mo，Sn为尾晕指示元素；近矿指示元素为Au，Ag，Cu，Pb，Zn。据此建立了构造地球化学找矿模型，确定了构造地球化学找矿预测标志，为深部找矿提供了地球化学依据。

Abstract:

Zhaoping fault zone is an important gold metallogenic belt in northwestern Shandong province. There are many superlarge, large and mediumsized gold deposits found on this belt. The mineralization of gold deposits has the characteristics of multistage and multistage superposition. Au, Ag, Cu, Pb, Zn, As, Sb, Bi, Sb, Bi, B, Hg, Mo and As are dizziness indicator element. Tectonic geochemical prospecting model has been established, and a tectonic geochemical prospecting prediction indicator has been identified. It will provide geochemical evidence for deep prospecting.
