Sulfur Isotope Geochemistry of Sn–Polymetallic Depositsin Dafulou District of Guangxi Province, China

Abstract:

The Dachang tin-polymetallic ore deposit is one of the largest Sn ore deposit in the world. For a long time, the Danchi mineralization belt was studied from different perspective, i.e., the mineralization age, the ore source, the deposit model, etc. In fact, the contradistinction of the three mineralization belts has an important macroscopic significance for deepen the genetic mechanism of the Danchi mineralization belt. In the Changpo ore deposit of the west mineralization belt, besides three δ³⁴S values (+4.794, +2.31, +2.6), the δ³⁴S values belong to negative value, yet in the Lamo ore deposit of the middle mineralization belt, most of the δ³⁴S values show positive besides two sulfur isotope sample (δ³⁴S=－0.36, －1.6). But in the Dafulou ore deposit of the east mineralization belt, the δ³⁴S values range from negative value to positive value. So there are only same ore resource partly for the Lamo ore deposit and the Changpo ore deposit. Overall, the ore source of the Dafulou ore deposit is more extensive than other ore deposit, and shares the same ore source with the other ore deposit.
