摘      要：The subeconomic Mount Novit Zn-Pb-Ag deposit is located approximately 20 km south of Mount Isa,*** contrast to the nearby Mount Isa,Hilton and George Fisher Zn-Pb-Ag deposits,mineralisation at Mount Novit is situated to the west of the regional-scale Mount Isa Fault and is hosted in the Moondarra Siltstone as opposed to the Urquhart ***-grade(10 wt.%Zn+Pb)mineralisation occurs as a matrix supported breccia dominated by sphalerite and pyrrhotite with galena,pyrite,and ***-situ U-Pb geochronology was completed on apatite and two textural varieties of ***-grained(10 ppm),possibly reflecting the leaching of the metals from an underlying basement *** GGIMFis geothermometer(Frenzel et al.,2016)produced a mean formation temperature of 345±52℃.The timing and temperature of Zn-Pb-Ag mineralisation is consistent with the age and cooling temperature of apatite presented in this *** on these correlations,we
