萬宜水庫東壩(浪茄灣)

今日由西貢市坐了一百多元計程車到萬宜水庫東壩，雖然山長水遠，但這個地方其實很有趣，也是世界知名的地方。我在英國見過這個地方的介紹。

Spectacular columnar jointing is seen in the area of the east dam, with hexagonal columns averaging 1 to 2 m in diameter and extending to depths of at least 80 m. Fiamme lying parallel to the column base, indicate a gentle dip to the southeast. Some kinking of the columns may represent differential laminar shearing associated with post-depositional secondary flow structure. (CEDD)
