| 摘 要： | 依据矿物热电性与地质找矿的关系和原理,通过对矿物热电效应机理及影响热电性因素的讨论与分析,结合大洋矿物热电性标型的初步研究,发现金属或半导体矿物处在温差条件下可产生热电效应,热电性标型可指示矿物形成的环境及物理化学条件,为地质与找矿提供指示信息以实现其应用。根据矿物热电性标型可判断古地温和成矿温度、预测隐伏矿体、研究成矿分带性、评价矿床剥蚀水平等,可望在大洋地质与找矿领域发挥重要的作用。

| Abstract: | The thermoelectric effect represents interactions between electrical and thermal transport,that is,a thermal gradient causing an electric field.As a typomorphic characteristic,thermoelectricity of metal-semiconducting minerals can denote the physical-chemical conditions of mineral formation,and therefore can be applied to the exploration and evaluation of ore deposits.In order to probe into the relation between the thermoelectric typomorphic characteristics and prospecting,the principle involved in the thermoelectric effect of minerals and the factors influencing the thermoelectric power are discussed,and the application of thermoelectric typomorphic characteristics to prospecting is elucidated on the basis of the latest research on minerals from the land deposits and the Pacific Ocean respectively.It is shown that a database of information regarding the determination of basin paleotemperature,the estimation of mineralization,the prediction of concealed ore bodies,the study of metallogenetic zonation,and the evaluation of denudation extent of ore deposits can be obtained through characterizing the thermoelectric effect of minerals. |
