Cosmogenic-radionuclide Profile of the Mocs Meteorite Strewnfield

Cosmic-ray produced nuclides were measured in samples from eight pieces of the L5-6 chondrite Mocs from known locations in the strewnfield. We measured 10Be and 26Al in the bulk phase along with 36Cl in both the metal and silicate phases. Relationships of the activities of these radionuclides from various meteorite pieces in the Mocs strewnfield provide new insight into the association of meteorite fragments to each other in the pre-atmospheric parent body. Results suggest a >2pi irradiation for the Mocs meteoroid which was less than 1 meter in radius.
