✦ Synopsis

Analcime has been synthesized from natural rhyolitic tuff and green tuff (Miocene age) at 200 ~ C and 20 kg/em 2 with solution of ~qa2SiO 3 (12%) in 50-to 260-hr runs. :From the diffraction intensities, it was found that the alteration products of green tuff contained more analcime than those of rhyolitic tuff. It has been concluded that the lithological character of starting materials and the chemical behavior of reaction products are important controlling factors in anMcimization.
