On the distribution of a few elements in Hokutolite

Abstract

Hokutolite is particular interest of the hot spring deposit mineral with native radioactive elements. A discussion is given of preliminary results of an X-ray microanalyser on Hokutolite which found in Tamagawa Hot Spring, Akita Prefecture. The Ka pictures of Ba, Pb, and S show the homogeneous distribution of these elements in white and brown layeres of the sample. The FeKa image shows a vein-type distribution in the white layer. On the relation of Fe, Pb, and radioactive elements, the author have tried to suggest possible avenues for the future study.
