Extract

During 1907, a plumbiferous barytcs, deposited by a hot spring at Hokuto in Taiwan (Formosa), was discovered by Mr. Y. Okamoto. This mineral, although a special name ‘hokutolite’ was proposed for it by Professor K. Jimbō in 1912, is a variety of barytes. It shows a slight difference in its chemical composition as well gs its physical properties from ordinary barytes.
