Unraveling the precise mineralization age is vital to understand the geodynamic setting and ore forming mechanism of the sediment hosted Pb Zn deposit; this has long been a challenge The Sichuan Yunnan Guizhou SYG triangle in the southwestern margin of the Yangtze Block is a globally recognized carbonate hosted Pb Zn metallogenic province and
The Sichuan Yunnan Guizhou metallogenic province of Southwest China contains more than 200 Mt of Pb Zn ore in carbonate hosted Pb Zn deposits representing 27% of the total Pb and Zn resources of China Sources of metals and pathways of ore forming fluids were elucidated through a study of the Pb Zn S Cd isotopic compositions of sphalerite
Rare metals Ge Ga In Cd are key resources for the development of green technologies and are commonly found as trace elements in base metal mineral deposits Many of these deposits are in orogenic belts and the impact of recrystallization on rare metal content and distribution in sphalerite needs to be evaluated Based on laser ablation inductively coupled
Pb Zn system has large miscibility gap in the liquid and a monotectic and eutectic reactions at lower temperatures [43 56] Mutual solid solubilities of Pb and Zn are essentially negligible [43 56]

The Wusihe carbonate hosted Zn Pb deposit Mt Zn Pb at a grade of % Zn and % Pb is the largest deposit in the Dadu River Valley district of the Sichuan Yunnan Guizhou metallogenic province of southwest China Three types of orebodies occur 1 stratiform banded and lamellar within dolomite of the Neoproterozoic Dengying Formation; 2 vein type;
The Sichuan Yunnan Guizhou Pb Zn metallogenic province located in the southwestern margin of the Yangtze Block is the most intensively developed region of carbonate hosted Pb Zn deposits in China Both the number of Pb Zn deposits/spots more than 500
The Pb Zn mineralization formed at low temperature 200℃ and the ore forming fluid migrated from the bottom to the top It is suggested that the ore genesis of Tianbaoshan Pb Zn deposit belong to the MVT deposit while the sphalerite is
Jinchanghe is a Zn Pb Fe Cu skarn deposit in the northern Baoshan block southwestern China It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper part Economic metals are also
The Santa María and Antares Zn Pb Ag skarn deposits in the Velardeña Mining District are located in central NW Mexico They lie 470 m apart along the contact between Oligocene felsic intrusions and Cretaceous limestones and were developed during prograde retrograde post ore Santa María and late stages Firstly the prograde stage was formed by

The top 40 stratiform Zn Pb Ag deposits based on Zn Pb wt % grade 17 Tonnes of metal versus Zn Pb grade showing the giant and supergiant stratiform sediment hosted Zn Pb Ag deposits
The classification of lead zinc Pb Zn deposits has been a highly controversial issue From the standpoint of evaluating the potential of mineral resources we construct a Pb Zn deposit predictive type of classification scheme and propose a Pb Zn deposit comprehensive classification scheme including 5 classes and 13 sub types that regards
The giant Fankou Zn Pb deposit is ranked as the third largest Zn Pb deposit second to the Huoshaoyun and Jinding in China Leach and Song 2019 It is characterized by the large size with exceeding 10 Mt Zn Pb metals high grade grading at 15 wt% complex concealed orebodies exceeding 300 m below subsurface and abundant associated
As one of the famous high grade Pb Zn ore fields in the Sichuan Yunnan Guizhou ore concentration area the Tianbaoshan Pb Zn deposit which is located on the southwestern margin of Yangtze Craton has a total Pb Zn reserve of
