maar [mär]
(geology) A volcanic crater that was created by violent explosion but not accompanied by igneous extrusion; frequently, it is filled by a small circular lake. Maar a funnel-shaped or cylindrical depression of volcanic origin, formed on the earth’s surface during a single gas explosion not accompanied by the extrusion of lava. They are up to 3,200 m across and 300-400 m deep. Maars are often ringed by ridges made up of fragments of rock shattered by the gases. In wet climates maars often fill with water and form lakes, for example, the Laacher See in the Eifel massif (Federal Republic of Germany) and Lakes Pavin and La Godivelle in Auvergne, France.
