Samail Ophiolite
The Samail Ophiolite (also spelled Semail Ophiolite) of the Hajar Mountains of Oman and the United Arab Emirates is a large slab of oceanic crust, made of volcanic rocks and ultramafic rocks from the Earth's upper mantle, that was overthrust onto continental crust as an ophiolite. It is located on the eastern corner of the Arabian Peninsula and covers an area of approximately 100,000 km2. Based on uranium-lead dating techniques, the Samail Ophiolite formed in the Late Cretaceous. It is primarily made of Silicate minerals, silicate rocks with (Silica, SiO2) content ranging from 45–77 wt%. The Samail Ophiolite is important because it is rich in copper and chromite ore bodies, and because it also provides valuable information about the ocean floor and the upper mantle on land. Geologists have studied the area, attempting to find the best model explaining the formation of the Samail Ophiolite.

Arabian Plate Map With Semail Ophiolite Location
The Arabian Peninsula, (; ar, شِبْهُ الْجَزِيرَةِ الْعَرَبِيَّة, , "Arabian Peninsula" or , , "Island of the Arabs") or Arabia, is a peninsula of Western Asia, situated northeast of Africa on the Arabian Plate. At , the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE), and Yemen, as well as the southern portions of Iraq and Jordan. The largest of these is Saudi Arabia. In the classical era, the southern portions of modern-day Syria, Jordan, and the Sinai Peninsula were also considered parts of Arabia (see Arabia Petraea). The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf and the Gulf of Oman to the northeast, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Oce ...
