Lappajärvi is a lake in Finland, in the municipalities of Lappajärvi, Alajärvi and Vimpeli.〔 It is formed in a wide, partly eroded meteorite impact crater. The lake is part of Ähtävänjoki ((スウェーデン語:Esse å)) basin together with Lake Evijärvi that is located downstream (north) of it. The Lappajärvi impact structure is estimated to be 76.20 ± 0.29 million years old (Campanian stage of the Late Cretaceous time period).〔(【引用サイトリンク】publisher=Schmieder M. & Jourdan F. (2013) Geochimica et Cosmochimica Acta, vol. 112, p. 321-339 )〕 An island in the middle of the lake, Kärnänsaari (Kärnä Island), gives the name to the black impact melt rock (impactite) found there, locally called kärnäite.〔http://www.gastro.physics.helsinki.fi/tutkimus/geo/kiintea/lappa.html〕 The towns on the shore are Lappajärvi and Vimpeli. Although not very near any, the nearest major city is Seinäjoki. ==Gallery== File:Lappajärvi.jpg|Lake Lappajärvi File:Lappajärvi, july 2014.JPG|Lake Lappajärvi File:Lake Lappajärvi 2015-02-15.JPG|Frozen in winter 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「Lake Lappajärvi」の詳細全文を読む スポンサード リンク
