This paper is based on microprobe analysis (Ta, Nb, Fe, Mn, Ti, W, Sn) and Fe 3+ EPR spectra of cassiterite samples from 14 tin deposits from the Iberian Hercynian Massif. The interpretation of microprobe data, atomic ratios (Fe+Mn)/(Nb+Ta), and Fe 3+ EPR spectra reveal that the coupled substitution: 3Sn 4+ = (Fe,Mn) 2+ + 2(Nb,Ta) 5+ is …Web

Introduction. Cassiterite is a tin oxide (SnO 2) mineral, which is economically important as the primary tin ore and an associated mineral in some tungsten and volcanogenic massive sulfide (VMS) ore (Sainsbury, 1969; Taylor, 1979; U.S. Geological Survey, 2014).It belongs to the mineral group of rutile (TiO 2), which is a common U-Pb …Web

during the past 60 years (Schwartz et al. 1995), but in recent years, Myanmar tin production has greatly increased owing to the newly discovered tin mining district at Man Makhsan in the Wa State. This made Myanmar the world's third-largest producer of tin after China and Indonesia in 2014 (Gardiner et al. 2015b; Htun et al. 2017).Web

The Myanmar production increase came from a new mine site in Wa State, and not from the traditional tin-producing areas in the South.

Although Myanmar was a major tin and tungsten producer pre-World War II, since the 1960s much of its mining industry has been an essentially artisanal operation, in 2013 representing less than 0.1% of the country's GDP (Gardiner et al., 2014). This emergence of Myanmar is a potential "Black Swan" event in tin production – an event …Web

Myanmar, the third largest global tin supplier, is an important component of the Southeast Asian tin province.
