It covers an area of 4.50 square kilometres (approx.). It is not a quaternary volcanic island, but rather is believed to be an upthrusted part of upper mantle material. The nearest island is Rocky Island. The island is slightly north of the Tropic of Cancer, and its highest point is 235 metres. ==Geology== The island is considered geologically unique as it is uplifted mantle, a fragment of the sub-Red Sea lithosphere. Rocks on the island are mainly lower crustal metamorphic rocks. The island became present above sea level after African and Asiatic continental plates converged to cause rocks in the lower crust to be uplifted. The island comprises three massives of peridotite, which are rich in the gemstone peridot (olivine). This gem makes the island notable as it is believed to be the first discovered source of peridot, which was called topazios in ancient times, hence the Greek name for the island, ''Topazios''. Layers of spinel-lherzolites with anhydrous Al-diopside pyroxenites and hydrous Cr-diopside pyroxenites can be found too on the island. The presence of all of these minerals has led to mining on the island which dates back as early as ancient times. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「St. John's Island, Egypt」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
