文摘Based on the proposal by Witten,De Rujula and Glashow,we carried out the experimental search on two meteorites for the fossil tracks formed by cosmic nuclearites with masses ranging from M~6×10^(-4)g up to very large mass.An upper limit 2km-2y-1(2πsr)-1 was obtained for the cosmic nuclearites with masses larger than 6×10^(-4)g which passed through these meteorites.
