Awali Structure (Jabal Al-Dukhan )

Jabal Al Dukhan dome, located 20 km south of Manama, rises 134m above sea level and is the highest point in Bahrain, is an oval-shaped structure. Which consider one of the best outcrops to tell us about the surface geology of Bahrain, The Sediments ranging in age from early Eocene to middle Miocene are exposed at the surface of the dome. And also to know the story oil discovery in the southern part of the Gulf region

Sabkah

Participants will have the opportunities to see the Sabkha features, however Sabkha is a transliteration of the Arabic word for a salt flat. Sabkhas are supratidal, forming along arid coastlines and are characterized by evaporite-carbonate deposits with some siliciclastics. Sabkhas form subareal, prograding and shoaling-upward sequences that have an average thickness of a meter or less. The accepted type locality is along the coast of the Arabian Gulf.

Tree of Life

The Tree of Life is a well known natural feature in southern Bahrain. The tree is an isolated phenomenon in an otherwise barren area. Not a single other tree of whatever size occurs in this area. It is not obvious where the tree gathers the water essential for its survival.

The Tree of Life is located on a ridge between a karsted basin in the south and a dry surface area in the north. The karsted area is covered with sulfates and salts which prohibit the survival of trees. The dry area in the north provides too little water for the survival of trees. The possible explanation for the water resource of the tree may be found in the shallow geological structure of the area. Close to the tree the dry rocks of the Rus formation outcrop. There is a possibility for an aquifer just below the Rus formation, which provides the Tree of Life with its water.
