摘要
通过某金矿床黄铁矿晶体形态和热电系数等标型的研究，指出不同阶段、不同矿化类型和不同标高晶形和热电系数、导型的演化趋势及其与金矿化的关系，发现了矿体从＋２０ｍ标高→－７０ｍ标高，矿体经历了一个“再现→尖灭”的过程，并从晶形的角度定量地模拟出标高与单形晶｛１００｝＋｛ｈｋ０｝含量和的关系方程，从而算出了矿体尖灭再现的纵向距离为９３ｍ，借助于计算机有效地找到了矿物学填图参数——黄铁矿热电系数均方差，进行了矿物学填图，对矿体进行深部定位预测。
Research of typomorphic peculiarities,such as crystal forms,pyroelectricity of pyrites indicates the relations between the gold mineralization and the typomorphic peculiarities of pyrite. It also shows a complete process from thinning out to reproduction of ore bodies from +20m to -70m in depth.The relative equation between height and the total content of the single crystal,including {100} and {hk0} has been quantitatively modelled, then the longitudinal separation is 93m between the thinning out position and reproduction position of ore bodies.As to the location prognosis of ore bodies in depth,the mineralogical mapping parameter,the meandeviation of the pyroelectric coefficient has been found with the aid of computer.
