Abstract

We have performed a geophysical search for fractionally charged particles (mainly ql quarks) in sea water and rock sample's. The samples,chosen were ten rock samples, which are believed to have been at the earth's surface for a long time, and two three-liter sea water samples. The samples were run through cation exchange columns to separate most of the material from particles of charge ±.2/3 and ± 1/3. The purified samples were then evaporated in an electron gun, which accelerated the negatively charged particles to a solid state detector. The pulse height spectra from the detector were scanned for peaks corresponding to particles of a charge between minus one and zero. No such particles were found. The concentration of ql quarks in the rock samples was < 10^-23 quarks/nucleon and in the sea water samples was ~< 10^-24 quarks / nucleon.
