Abstract

The Boltysh crater has an entire suite of crater-fill impactites preserved, including two impact melt- bearing breccias. Smectite occurrence in the breccias suggests two stages of alteration; an early hydrothermal mineralization, and a later, low temperature weathering. δD and δ¹⁸O of smectite separates are currently being measured and will be presented.
