ABSTRACT: The Miocene alkali
basaltic rocks cover the northeastern part of Jordan, within Harrat Al-Shaam
plateau. The volcanic concentrated along the Dead Sea boundary and spread
around the north east of Jordan area, and was considered as interplat volcanic
field in Jordan. The volcanic basalt is associated with xenoliths fragmental
rocks or xenocryst minerals. Nine samples were collected from the study area
and analyzed for XRD, XRF and SEM. These samples presented the xenoliths rocks
and minerals existing in the study area. This study is focused on the garnet
and pyroxene xenoliths minerals in Tulayl Al-Hasna area within Ufayhim
Formation. Hand samples are characterized by coarse aggregates of garnets up to
(2 cm in diameter) with dark brown to red color, and highly fresh fractures.
Also, the pyroxene (
