EN

Concentration and isotopic composition of noble gases have been measured in bulk samples of the L5 chondrites Baszkówka and Mt. Tazerzait. Compared to other chondrites both meteorites have very large cosmic-ray exposure ages of 74 and 60 million years, respectively. During their history both meteorites were not involved in major thermal events.
