Abstract
The study of the Al-Bayda pluton comprises petrography and chemistry of thé different granite varieties which are related to the basement rocks in the south eastern sector of the Yemen Arab Republic. According to the modal and chemical data, the present granite can be classified as syeno-granite and kali-granite, respectively. In the Al-Bayda granites, a perthitization had taken place through exsolution and replacement processes. Generally, the investigated granites were crystallized from an acidic melt during a very limited differentiation stage. Finally, the Al-Bayda granites suffered greatly from metasomatism at a postmagmatic stage producing a type of granite related to the anomalous group.
