Geography
Muscat is located in northeast Oman, at 21°N, 57°W. The Tropic of Cancer passes south of the area. It is bordered to its west by the plains of the Al Batinah Region and to its east by Ash Sharqiyah Region. The interior plains of the Ad Dakhiliyah Region border Muscat to the south, while the Gulf of Oman forms the northern periphery of the city. The water along to coast of Muscat runs deep, forming two natural harbours, in Muttrah and Muscat. The Western Al Hajar Mountains run through the northern coastline of the city.

Volcanic rocks are apparent in the Muscat area, and are composed of serpentine and diorite, extending along the Gulf of Oman coast for ten or twelve 16 km from the district of Darsait to Yiti. Plutonic rocks constitute the hills and mountains of Muscat and span approximately 30 mi from Darsait to Ras Jissah. These igneous rocks consists of serpentine, greenstone and basalt, typical of rocks in Southeastern regions of the Arabian Peninsula. South of Muscat, the volcanic rock strata is broken up and distorted, rising to a maximum height of 6000 ft, in Al Dakhiliyah, a region which includes Jebel Akhdar, the country's highest range. The hills in Muscat are mostly devoid of vegetation but are rich in iron.
