New Application of Highly Vesicular Basalt from Jabel Isbil Volcano (Dhamar-Rada'a Volcanic Field), Yemen

Positron Annihilation Spectroscopy of Basaltic Rocks from Plio-Qaternary Volcanics, Sana’a-Amran Volcanic Field, Yemen

“…The olivine basalt samples have small values of W-parameter in comparison to the other samples from other location indicated that the positrons annihilated with the valance electrons are more than that annihilated with core electrons. Recently, the vesicular basalt in Isbil volcano, SE Yemen, which is identical to the same rock types in the present work, it is successfully used as natural catalysis in some chemical reactions [22] and semiconductor materials [23].…”
