Fractures system within Dammam Dome and its relationship to the doming process, Eastern Saudi Arabia

Dammam Dome is an oval-shaped structure that covers an area of about 500 km² and encompasses Al Khobar, Al Dhahran and part of Ad Dammam cities, east of Saudi Arabia. The dome characterizes by the presence of well developed fractures system that exposes at its apex and extends to its peripheries. Based on their size, trend and extent, fractures within Dammam Dome are divided into three types: regional (major) fractures, local (minor) fractures and very small size-localized fractures. This study discusses the criteria used in classifying those fractures, and the relationship of the regional (major) ones to the doming process. A model for the trends pattern of fracture is suggested for those fractures, and examined with the concentric and radial fracture pattern associated normally with dome structures. The suggested model is compatible and concordant with the dome model, which proves that the major fractures in the area are related to the dome emplacement and process. Outcomes and findings of this study are crucial for understanding the behavior and distribution of fractures associated with domes. Additionally, the suggested model of fractures and their trend pattern is important model in similar setting for hydrocarbon exploration and for any urban development and major constructions within the Dome vicinities.
