OMAN navi !! (Welcome to Oman）

The center part is soil vague. The steep slope continues toward to the coast.
The major industry is a fishery, also oil and gas, and the mineral resource are buried under the inland. There is a Sanctuary of Arabian Oryx, also.

A vague soil means empty space.
The desert which is called SAND DUNE would be only 15 % of the entire desert.
