Abstract：The Tangchun tungsten (tin) deposit is a newly discovered quartz vein type deposit and the potential for prospecting is huge.The deposit occurs in the western outer contact zone of the Longwo granodiorite pluton in Eastern Guangdong Province.The ore-hosting strata are the clastic rocks of the Lower Jurassic Jinji formation, which are considered to be the youngest orehosting strata in the Nanling and its adjacent areas.On the basis of detailed field geological surveys, a muscovite 40Ar-39Ar plateau age of 150±1 Ma and an isochron age of 149±2 Ma (MSWD=1.20) have been obtained for a W-bearing quartz vein in the deposit, which are the same within the analytical uncertainties.Our 40Ar-39Ar dating results have shown that the Tangchun tungsten (tin) deposit was the product of early Yanshanian large scale petrogenesis and metallogenesis in the Nanling Range.The newly discovered Tangchun tungsten (tin) deposit is of great guiding significance in exploration since it not only broadens our mind in prospecting for quartz vein type tungsten-tin deposit, but also provides an opportunity to thoroughly unravel the metallogenic regularity as well as metallogenic models of the quartz vein type tungsten-tin deposit.
