The JTGM is mainly composed of foliated peridotite (harzburgite
and dunite) and covers an area of about 150 km2.

The peridotite unit rocks are the most altered part of Noorabad ophiolite including dunite, harzburgite
Sarimbey volcanic assemblage (spilitic basalt, andesite unit), Artova ophiolite complex (serpentine, harzburgite
, dunite, gabbro, diabase, chert), and Cretaceous limestone blocks are also observed in the area.
In this respect the Olive Highlands are geologically and geochemically distinct from most of the Hajar Mountains to the north (e.g., Wadi Wurayah National Park and surrounding areas) and to the south (e.g., the Hatta area southward to Wadi Jizzi and beyond), which are composed primarily of a rock called harzburgite
is extremely low in silica and is therefore classified as "ultrabasic".
Ishiwatari  reported that harzburgite
is observed predominantly in the Oshima peninsula area and originated from the upper mantle after the extraction of roughly 35% volume of basaltic magma.
