Abstract:

The Maty - Du Long area has a high potential of tin ore, which demonstrates quite good quality. Sn content varies from <0.1% to 1.44%, an average of 0.2%, meeting the basic industrial criteria for commericial tin mining. The research results show that tin mineralization mainly occurred along the Northeast - Southwest fracture system in the greisenized biotite granite of the Ca Na complex and the volcanic rocks of the Don Duong Formation. The results have allowed us to identify 5 tin mineralization zones, which are Suoi Giang, Tap La, Dong Thong, Khen Den and Ta Nan and, the total reserve of tin ore in Ma Ty - Du Long area is estimated at ~5,968 tons
