摘要:
小秦岭金矿田位于华北陆块南缘金、钼、铅、锌多金属成矿带上，其内矿床为受剪切带控制的叠加改造型热液矿床。为研究剪切带对矿体的控制规律，从小秦岭金矿田内典型矿床的赋矿构造出发，对构造性质及形成演化过程进行了系统调查研究，发现其先后经历了韧性剪切、脆-韧性剪切、韧-脆性剪切及脆性剪切4个构造变形阶段，金矿化强度与剪切带规模及构造密度呈正相关，且含矿剪切带的产状变化对矿段及矿体的分布起决定性作用。

Abstract:
Xiaoqinling gold field is located on the gold,molybdenum,lead,and zinc polymetallic mineralization belt on the southern margin of the North China Craton.The ore deposits in this field are superimposed and transformed hydrothermal deposits controlled by shear zones.To study the ore-control regularity of shear zones on ore bodies,a systematic investigation and research on the structural characteristics and formation-evolution processes were conducted based on the ore-controlling structures of typical deposits in the Xiaoqinling gold field.It was found that the field has experienced 4 structural deformation stages: ductile shear,brittle-ductile shear,ductile-brittle shear,and brittle shear.The intensity of gold mineralization is positively correlated with the scale and structural density of shear zones,and the variation of ore-bearing shear zone occurrence plays a decisive role in the distribution of ore sections and ore bodies.
