The Xiling gold deposit,located on the east side of the Sanshandao gold deposit,is currently the largest gold deposit and deepest gold deposit newly discovered in the Jiaodong gold concentration area.Based on the geological observations,the thermoelectric characteristics of pyrite with different depths(-699 m,-1 190 m,-1 602 m,-2 274 m,and -2 615 m below sea level) in the Xiling gold deposit were analyzed.The results show that the dispersion range and degree(14.59~46.72) of pyrite thermoelectric coefficient in the Xiling gold deposit are generally wide and relatively steady.The thermoelectric conductive type of pyrite at the shallow elevations,such as the -699 m and -1 190 m below sea level,is N-type,while that of pyrite at the deep elevations(-2 615 m below sea level) is P-type.The ore-forming temperatures are mainly concentrated at 250~360 ℃,which is generally consistent with the homogenization temperatures of quartz fluid inclusions,thus belongs to a medium-high temperature hydrothermal gold deposit.The calculated gradient value(0.00~0.29) of the thermo-electric conductive type of pyrite is small,and the estimated denudation rate of the orebody is 75%.Combined with the various parameters of the thermoelectric characteristics of pyrite,it is considered that there is a great potential for exploration in the deep part of the Xiling gold deposit,and the metallogenic depth can reach to -3 000 m below sea level. According to the known regularity of lateral prostration that gold orebodies plunge NE,it is proposed that the potential deep gold orebodies plunge NE to the -3 000 m below sea level is an effective location for deep exploration targets.Through the study of the thermoelectric properties of pyrite in the Xiling gold deposit,it can provide a scientific basis for the deep exploration and prediction of many gold deposits in the Jiaodong gold concentration area.
