Five barites from North America were analyzed for the abundance and isotopic composition of Kr and Xe in an attempt to find 131Xe anomalies from the capture of epithermal neutrons on 130Ba. Excess 131Xe was found in two of the samples, 118B from Pea Ridge Mine of Sullivan, Missouri, and 119B from Franklin, New Jersey. The highest enrichment of 131Xe (108%) was observed in the gas released from sample 118B. The enrichment of 131Xe for sample 119B is 27%. We show that the neutron source for the reaction 130Ba(n, γ) --> 131Xe is the decay of actinide elements in the host rocks. However, no prominent anomalies were observed from the presence of fissiogenic xenon.
