Abstract：
An experiment to search for stable superheavy nuclearites and quark nuggets in different meteorites has been performed using the Rutherford backscattering technique.The upper limit of the relative concentration of nuclearites with Z≈100,A≈1000 in the meteorite samples about 2ppm is obtained.
