Persian Gulf Basin of approximately 93000 square miles. The name Persian Gulf in most cases refers not only to the Persian Gulf but also the Gulf of Oman, the Strait of Hormuz and various outlets that are linked to the Arabian Sea. The Arabian Plate tectonic origin is grouped into six phases which contributed to its current geology: The early Precambrian (from 800 to 650 Ma) is a compressional phase where a series of islands-arcs and micro-continent terrane accreted to form the oldest portions of the Arabian Plate (Gondwana). The development of Hormuz saltbasin was a consequence of the last Precambrian orogenic event.
Persian Gulf naming dispute naming the "Arabian Gulf as the Persian Gulf" is that the Red Sea was named Arabian Gulf back then, which "prevented the Arabian Gulf from being named as Arabian Gulf, and instead the name Persian Gulf became common". According to a book "Documents on the Persian Gulf's name" (pp 92–98), the United Nations Secretariat and its specialized agencies have requested its staff to use only "Persian Gulf" as a standard geographical designation. The United Nations Group of Experts on Geographical Names discussed the naming issue during its 23rd session, held in Vienna from 28 March to 4 April 2006. According
