| Abstract: | Fankou lead-zinc deposit of Guangdong province is occurred in Late-Paleozoic carbonate stratum,and restricted in NNE-trending faults and subsidiary fracture.Homogenization temperatures of fluid inclusions from quartz,sphalerite and calcite are range from 115℃ to 300℃,while average is 189℃.Decrepitation temperatures of ore minerals are range from 155℃ to 330℃,modal value are 220~280℃.The sulfur isotope composition have got the tendency of δ34SPy>δ34SSp>δ34SGn,the sulfur isotope balance temperatures are calculated to be 105 ~ 334℃,while the modal value are 150 ~ 250℃.All the above temperature date indicated that the ore-forming fluid of Fankou lead-zinc deposit belonges to mesotherm fluid.The ore-forming fluid is origin from mixing of magmatic fluid,metamorphic fluid and geothermal brine which are revealed by oxygen and hydrogen isotopic analysis.Integrated the former research and our field investigate,Fankou lead-zinc deposit is a typical medium-low temperature hydrothermal deposit related to magma activity. |
