| Abstract | ||||
| The Marib - Sirwah volcanic field is structurally represented by major graben. The Marib Graben is a relatively narrow deeply subsided structure lying between the Gabal Hilan in the northwest and the Gabal Al-Balaq Ridge in southeast area. Remote sensing techniques with DEM were applied to delineate lithological and structural features of the area around Marib area, Yemen. Landsat Enhanced Thematic Mapper Plus (ETM+7) Satellite data have been used to identify the Marib - Sirwah volcanic field in Marib graben. The results revealed that the Marib area is covered by three different rock types related to three different ages: basement rocks, Amran limestone and volcanic rocks. Lineaments of the Marib area were grouped in three domains according to rock units and show maximum direction in NE–SW followed by NW–SE. | ||||
