Dassen Island is an uninhabited South African island in the Atlantic Ocean. It is situated about west of Yzerfontein and north of Cape Town. The flat and low-lying island measures about long northwest-southeast and wide, with an area of .〔http://web.uct.ac.za/depts/stats/adu/dassen.htm〕 It is a proclaimed nature reserve. In Dutch the word "dassie" means (approximately) "rock-rabbit", the plural being "dassen" and the island is named after the colonies of hyraxes (Procavia capensis) encountered there by the discoverers. Named Ilha Branca ('white island') by the early Portuguese mariners, it was renamed Elizabeth Eiland by Joris van Spilbergen in 1601. The form Dasseneiland (Dutch/Afrikaans) is preferred for official purposes. The island is underpinned by a fine-grained tourmaline granite, with a few zones of biotite granite. The intrusive rocks (late Precambrian) are in part covered by sand. Along much of the shoreline large, rounded boulders protrude from the sand to heights just above the high water mark. Although temporary pans form during the wet season (winter) in the interior, there is in general little fresh water on the island. Except on its eastern side, Dassen Island is surrounded by reefs. Many ships have come to grief here. ==External links== * (Dassen Island Images and Animals ) 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「Dassen Island」の詳細全文を読む スポンサード リンク
