棋盤石 (Tessellated Pavement) 位在澳洲塔斯馬尼亞 (Tasmania) 鷹頸地峽 (Eaglehawk Neck Isthmus) 北方，是一塊巨大的海蝕平台，海浪日夜不停地淘刷海崖，久而久之海崖逐漸崩退，形成和海平面近乎同高度的平坦岩石，這種地形就稱之為海蝕平台。位於海盜灣 (Pirates Bay) 北方海岬附近的海蝕平台尤為廣闊，緩斜的岩層面上有相交的節理。受到大自然力量切割，景觀類似棋盤，縱橫排列整整齊齊，令人讚嘆大自然的鬼斧神工公仔箱論壇* U- H; v$ c+ h

塔斯曼尼亞省（英文：Tasmania）係澳洲唯一嘅島省，原名范德文領（英文：Van Diemen's Land），位於澳大利亞東南面，係一個呈三角形嘅大島，同澳洲本土最南面嘅維多利亞省首府墨爾本隔海相望。塔斯曼尼亞喺六個省之中佔地面積最細，係澳洲自然生態保護得最完善嘅地方，最大城市係首府霍巴特公仔箱論壇% M% b; L2 }* o2 V) t- ~6 i9 Y+ O
塔斯曼尼亞號稱「天然嘅省」，亦被譽為「蘋果嘅島」，亦有「澳洲版嘅新西蘭」之稱，以秀麗風光同埋樸素人文為特色。作為獨立島嘅地理令當地有較大嘅未開發天然地帶，全省約40%被正式列為國家公園、自然保護區或者世界自然遺產地.2 m6 p: n* T+ q; K- G3 ]

A tessellated pavement is a rare erosional feature formed in flat sedimentary rock formations lying on some ocean shores. The pavement bears this name because the rock has fractured intopolygonal blocks that resemble tiles, or tessellations. The cracks (or joints) were formed when the rock fractured through the action of stress on the Earth's crust and subsequently were modified by sand and wave action. 公仔箱論壇8 A* _8 g; p& p' G( _

The pan formation is a series of concave depressions in the rock that typically forms beyond the edge of the seashore. This part of the pavement dries out more at low tide than the portion abutting the seashore, allowing salt crystals to develop further; the surface of the "pans" therefore erodes more quickly than the joints, resulting in increasing concavity.

A characteristic example of this formation may be found at Eaglehawk Neck on the Tasman Peninsula of Tasmania. This example consists of two types of formations: a pan formation and a loaf formation.
( {8 [) a9 j, ?) X0 D0 P2 ~公仔箱論壇The loaf formations occur on the parts of the pavement closer to the seashore, which are immersed in water for longer periods of time. These parts of the pavement do not dry out so much, reducing the level of salt crystallisation. Water, carrying abrasive sand, is typically channelled through the joints, causing them to erode faster than the rest of the pavement, leaving loaf-like structures protruding.

管見以為, 此景列自然奇觀, 殆無異議, 唯若與所云滇境兩勝相較, 則失色多矣, 遑論乎媲美也. 它景如其名, 直似棋盤一面, 頗見呆板. 瑟縮海灣一隅, 規模遠遜之外, 既缺昆明石林突兀崢嶸，姿態各異之奇趣, 亦欠哈尼梯田壯麗眩目, 令人摒息的氣魄.
