Sulfur Isotope Composition

Lece magmatic complex in SE Serbia, part of the Serbo-Macedonian Metallogenic Province, is one of the most promising zones for lead, zinc and precious metals for the country. This complex was formed as a result of the post-collisional magmatic activity that lasted from Oligocene to Miocene. This study brings new lead and sulphur isotope data with an aim to constrain the origin of mineralizing fluids and to estimate the temperature of their formation. Galena from the Bakrenjaca locality shows high 207Pb/204Pb values implying that the lead was dominantly derived from the upper continental crustal geochemical reservoir which was probably recycled within the mantle and erupted during Tertiary post-collisional magmatism. Sulfur isotope composition of galena, sphalerite and pyrite show overlapping ?34S values in the range between 0 and 3? indicating a mantle origin of sulphur. Sulfur isotopes were also used to estimate the temperature under which the minerals were deposited forming a complex of veins. The calculated temperature is around 350?C. Since this temperature is too high for epithermal deposits, it is probable that the associated minerals weren?t deposited in isotopic equilibrium and other methods should be conducted for more precise temperature evaluation.

Lead Zinc

Central Yunnan lead-zinc polymetallic province in Sichuan-Yunnan-Guizhou metallogenic province has 50 large, medium and small acale of pb-zn deposits. Through contrast research, ore-bearing rock is developed from Kunyang group of Early Proterozoic to Triassic carbonate, ore body, which is characterized by low temperature and low salinity, is obviously controlled by faults, and is accompanied by a strong dolomitization and calciization. Possiblly, metallogenic epoch is Mesozonic. The ore-forming material mainly comes from strata itself, lesser from magmatic rocks. Underground thermal water is the main mineralized hydrothermal water.

Lower Palaeozoic

There is a lead-zinc (with subsidiary copper) metallogenic province on each side of the Vale of Eden. To the east the veins of the Alston Block are found in Carboniferous rocks and a Hercynian age is the generally accepted date of the mineralization. To the west the veins lie in the Lower Palaeozoic rocks of the Lake District. Within the latter area ore-veins associated with the Shap Granite are, by common consent, regarded as of Caledonian age. But these apart, there is a regional mineralization in the Lake District, best developed in the northern part of that topographical unit, which has also been regarded as of Hercynian age.
