Abstract
A cascade impactor was flown on board a U-2 aircraft to gather particulate samples in the stratosphere at 18-21 km altitude after the El Chichon eruptions of 1982. Halite particles were observed, which posed a hazard for the catalytic destruction of ozone. No halite particles were observed a month after the eruptions, while a 40 percent increase in HCl was detected at 12 km, an increase which could have been augmented by halite transformations. The halite proportion of the volcanic clouds was of the same proportion of NaCl as in the volcanic ash around El Chichon. The results indicate that halite forms in eruption clouds of volcanos with alkalic magmas.
