曼加拉塹溝群

曼加拉塹溝(Mangala Fossa)是火星門農尼亞區11°36′S 151°00′W / 11.6°S 151.0°W / -11.6; -151.0附近一條發源於赫斯珀里亞紀亞馬遜紀年代的地塹,就位於溢出河道曼加拉谷的源頭。據認為曼加拉谷形成於同一地質時期至少二次從曼加拉塹溝釋放出的災難性洪水事件。洪水可能引發自阿爾西亞火山漫延出的岩脈入侵,這條岩脈衝破了積壓在含水層之上的厚厚冰凍圈(地下凍土層)。隨著地塹底部的下沉,水流沿地殼中的一條或兩條斷層向上湧出,形成地塹邊緣,並流入凹陷,最終注滿地塹,然後繼續沿邊緣最低點溢出,沖刷出了曼格拉谷河道[1][2][3][4][5][6][7]
