Identification of Coffinite in Radioactive Rocks of the Buller Gorge Region, New Zealand

Abstract

COFFINITE, the recently discovered hydroxyuranous silicate, U(SiO4)1–x ( OH ) 4 x 1 , has been identified as an essential primary constituent of radioactive arkosic grits and siltstones of the lower Cretaceous Ohika Group2 in the Buller Gorge region of the South Island of New Zealand. The identification is based on the characteristic X-ray pattern with lines at 4.68, 3.48, 2.66 and 1.78, and on the absence of thorium1,3. Fuller details will be published elsewhere.
