Mineralogy and authigenesis of zeolitic tuff from tall-junior and tall Amir, south Jordan

الملخص EN

Tall Amir and Tall Juhira are two important volcanoes located in southern Jordan.

Huge quantities of zeolitic tuff deposits are existed within basaltic rocks.

These two localities haven’t been investigated nor evaluated for their mineralogical and zeolitic content.

Zeolitic tuff from south Jordan is composed mainly of three components: Volcanic glass, primary rock forming minerals and secondary rock forming minerals.

Zeolitic tuff from Tall Juhira (ZTJ) are characterized by highly weathered red to brown color, and friable tuff.

The main zeolitic tuff minerals in ZTJ are phillipsite and chabazite.

Zeolitic tuff from Tall Amir (ZTA) is characterized by gray color and well-cemented tuff.

The main zeolitic tuff minerals are phillipsite, chabazite and analcime.
