involving drillholes, at the Bosumtwi impact crater, Ghana,
and the Lake El'gygytgyn, NE Russia. The title of the
article are 1. “Results of the 2004 ICDP Bosumtwi impact
crater, Ghana, drilling project First studies of the deep
impactite cores”, and 2. “Deep Drilling at Lake
El'gygytgyn, NE Russia in the International Polar Year”.
