＜四国カルストでの巡検について＞

およそ３億年前、赤道付近の海底火山の活動が始まり、その活動の終わった２億５千万年前頃、山頂付近にサンゴ礁などが堆積して出来た石灰岩が、四国カルストで見られます。移動する海洋プレートに運ばれて四国沖の南海トラフで大陸のプレートの下に沈み込んで行くときに削り取られて残った物が約２００万年前四国山地の造山運動で、標高１４００ｍまで押し上げられて出来ました。日本一標高の高いカルスト台地を見学し、カルストテラス内資料館にて、西日本の形成過程や現在の四国の地質について学習します。 

About 300 million years ago, volcanic activity began near the equator on the seafloor. Around 250 million years ago, after the volcanic activity ceased, coral reefs and other marine organisms accumulated around the summit, forming limestone. This limestone can now be seen in the Shikoku Karst. As the moving oceanic plate was subducted beneath the continental plate at the Nankai Trough off the coast of Shikoku, some of the material was scraped off and left behind. Around 2 million years ago, during the mountain-forming activity of the Shikoku Mountains, this material was uplifted to an elevation of about 1,400 meters, forming the present karst landscape.

We will visit the highest karst plateau in Japan and learn about the formation of western Japan and the current geology of Shikoku at the Karst Terrace Museum.
