摘　　要：早子沟金矿位于西秦岭褶皱带北部断褶带与中部裂陷槽之间的过渡部位,通过对早子沟金矿矿床地质特征、矿体地质特征及矿体品位变化特征的研究,建立了该矿床描述性模型、变异函数模型及金品位分形分布模型,探讨了矿区深部勘查的方向,并对矿区资源总量进行了估算。The Zaozigou gold mine is located in the transition zone between north fault-fold belt and central rift of western Qinling fold belt. This article analyzes the gold deposit geological features, the geological characteristics of the orebody and the orebody grade variation characteristics to establish the deposit descriptive model, variogram model and gold grade fractal distribution model. Finally, the direction of deep mine exploration is discussed and the total of mine resources is also estimated.
