Short summary
We collected particles carried by ascending flows and analysed them using transmission electron microscopy. Numerous sulfur-containing particles or particle aggregations were found in the ascending flows. In addition to S, the particles contained O, Ca, K, Mg, Fe, Na, Pb, Hg, Cu, Zn, As, Ti, Sr, Ba, etc. The sulfur-containing particles originated from deep-seated weathering or faulting products of concealed sulfide ore deposits. This is a previously unknown source of the atmospheric particles.
