| Abstract | Since ancient times, clay materials have been used as cosmetic and therapeutic materials due to their inherent physico-chemical properties. This study reports detailed mineralogical analyses of a clay
deposit in Baie-St-Ludger, eastern Quebec, as part of its assessment as a potential cosmetic or therapeutic clay material for external use. The samples were compared to a small suite of commercially available clay products of similar application.
These silty-clay to silt marine sediments are dominated by illite (biotitic) and plagioclase feldspar with subordinate amounts of K-feldspar, quartz, and amphibole (hornblende). Chlorite occurs only in minor to trace amounts. The commercial samples
generally contain more kaolinite and less non-clay silicates than the field samples. This difference should not be a deterrent for developing this deposit for commercial purposes, as at least one of the commercial products examined is mineralogically
similar. |
