中文摘要:
      地球物理探测是深部找矿预测不可或缺的重要手段,但是由于地质条件的复杂性及地球物理信息的多解性导致其地质解释的不确定性,需要通过多种途径加以限定。热电材料的电阻率和热导率具有明显的相关关系,但岩(矿)石的电阻率和热导率的关系鲜有研究。本文通过对前人岩(矿)石热导率和湖南岩(矿)石电阻率研究成果的梳理,发现岩(矿)石的热导率和电阻率具有明显的正相关趋势,认为这一规律有助于限定深部电阻率信息的地质解释。本文以湘南中生代钨锡多金属矿为例,初步探讨了岩(矿)石热导率和电阻率正相关趋势的深部找矿预测意义。
英文摘要:
      Geophysical exploration represents an indispensable method for deep ore prospecting, but the complexity of geological conditions leads to interpretation ambiguity of geophysical information and the uncertainty of geological interpretation, and needs constraints by multiple methods. There is a clear correlation between the resistivity and thermal conductivity of thermoelectric materials, but there is little study on this relationship of rocks (ores). On the basis of statistical analysis of the research results on the thermal conductivity and resistivity of rocks (ores) in the Mesozoic W-Sn polymetallic deposits in southern Hunan Province, this study identified a clear positive correlation trend between the thermal conductivity and resistivity of rocks (ores). This regularity can constrain the the geological interpretation of deep resistivity information. Taking the Mesozoic W-Sn polymetallic deposits in southern Hunan Province as an example, this paper preliminarily explores the significance of the positive correlation trend between the thermal conductivity and resistivity of rocks (ores) in deep ore prospecting.
