Vapor Element Transport in the Lunar Crust and Implications for Lunar Ore Deposits

Introduction: In planetary environments with stable H2O in the target (Earth, Mars), large impacts will generate extensive hydrothermal systems associated with the ejecta blankets [i.e. 1,2 and references within]. Although the Moon’s crust is considered to be dry by most standards (with the possible exception of the polar deposits), there are textures preserved in the lunar sample collection th...

Barite, Hematite and Cinnabar Ore Deposits in the Dusina Area, Mid-bosnian Schist Mountains

In the Dusina area, which is built up of Lower Palaeozoic metasediments, Devonian carbonate complex and Upper Palaeozoic metarhyolites unconformably overlain by Upper Permian sediments, numerous ore occurrences have been investigated: (a) "stratabound" metamorphic hematite deposits in the pre-Devonian metasediments; (b) epigenetic veins and pipes of barite (& calcite) with accessory Hg-tetrahed...
