"Combusting mudstones in the Smoking Hills area, Northwest Territories, were reported by European Arctic explorers in the early part of the 19th century. These sites emit hot sulphuric gases due to auto-combustion of pyrite-rich zones. The acidic gases react with the surrounding mudstones to precipitate brightly coloured mineral deposits. In this study, samples were collected from active burning sites (bocanne), inactive sites (klinker) and unaltered mudstones to characterize their mineralogy. The active sites are comprised of variable amounts of discrete sulphate minerals from seven different mineral groups, whereas the inactive sites are characterized mainly by jarosite, gypsum and quartz. The mudstone mineralogy shows most samples contain variable amounts of quartz, muscovite/illite, heulandite and jarosite and a host of other minerals in minor to trace amounts. Understanding the mineralogy of these sites provides new insights on formation of high-temperature acid minerals"--Abstract, page iii. Sulfate minerals Northwest Territories Analysis.
