In the space, along with increased distance from the main ore-controlling structures, the frequency of P type of pyrite and their thermoelectricity also decreased gradually. Within one lode, from the upper to the lower parts of an ore body, the vertical change of pyrite in thermoelectricity as the follows:① when the ore body is stable, that is when the ore body is uniformly and continuously mineralized, the Dp andαvalues keep increased from shallow to deeper parts;② when an ore body is discontinuously mineralized, the Dp andαvalues have a wavy increasing tendency from the shallow to the deeper;③ when the deeper part of an ore body contains abundant, Co and Ni high mafic dykes, the Dp andαvalues of pyrite decreased from the shallow to the deeper parts of an ore body, that is, an reversed zoning of pyrite thermoelectricity occurs for pyrite in this situation contain more Ni and Co and belongs to N type.④ For the deposits hosted in the Archean metamorphic rocks, because all of the pyrite in this case is N-type, the vertical change of pyrite is not featured by the transition of pyrite type, but by the increased values of Vnp and α from the shallow to deeper parts of an ore body.

在空间域上,水平分带规律为:随远离主干断裂,矿脉中P型的出现频率逐渐降低或热电系数值逐渐变小;在同一条矿脉中,这是由于矿化不均匀性及脉岩的影响,由矿体的上部到下部,它的垂向变化特征可以有如下几种变化形式:①由矿体的浅部到深部,黄铁矿的Dp值、或α值呈稳定升高的趋势时,矿体往往表现为矿化均匀,连续性好、延伸稳定;②由浅部到深部,黄铁矿的Dp值、α值呈波状变化,但总体又具有增大的趋势时,所在的矿体连续性差;③当矿脉的下部发育有大量的基性脉岩时,由于基性脉岩中常含有较高的Co、Ni,使其中黄铁矿的Co、Ni含量较高而呈N型导电,由矿体的上部到下部,黄铁矿的Dp值、α值呈减少的趋势,而造成黄铁矿热电性特征的逆向分带,④产于太古代变质岩中的中深脉状金矿,由于其中的黄铁矿均为N型导电,所以垂向变化规律并不表现为导型的改变,只是Vnp值或α值从矿体的上部到下部由小变大。
