艾瑞達尼亞湖

埃里達尼亞湖（Eridania Lake）是一座理論上曾存在過的火星古湖泊，面積約110萬平方公里。它位於馬丁谷溢出河道的源頭，並延伸至埃里達尼亞區和法厄同區^[1]。隨着厄里達尼亞湖在諾亞紀晚期的逐漸乾涸，它分裂成一系列較小的湖泊^[2]^[3]^[4]^[5]。

後來的火星專用小型偵察影像頻譜儀(CRISM)發現了厚度超過400米的厚厚沉積物層，所包含的礦物質有皂石（saponite）、滑石皂石（talc-saponite）、富鐵雲母（如海綠石-綠脫石）、鐵和鎂質蛇紋石、碳酸鎂-鐵-鈣及硫化鐵。硫化鐵可能形成於被火山噴發加熱的深水中，這種被歸類為熱液的過程可能是生命開始的地方^[6]。

來自埃里達尼亞湖底深水盆地的沉積物。地表上存在的桌山因受到深水/冰蓋的保護而免受強烈侵蝕。火星專用小型偵察影像頻譜儀的測量表明，礦物可能來自湖底熱液礦床，生命有可能起源於這片湖泊。
圖中顯示了火山活動如何導致埃里達尼亞湖底礦物的堆積，氯化物通過蒸發沿湖岸線沉積。
