Résumé

The Amapari Marker Band (AMB) is a unique resistant feature in the sulfate-rich Mirador formation (Mf), and is a feature that spans Mt Sharp, the central sedimentary mound within Gale crater, Mars [1]. From orbital observations, the AMB appears darker and retains craters, exhibits a high-Ca pyroxene signature, and varies in thickness [1]. The AMB was initially interpreted as a volcanic or more indurated sulfate deposit [1–2]. NASA Curiosity rover data has shown the AMB is a chemically and sedimentologically unique feature in the stratigraphy and only a thin interval in the Mount Sharp group (MSg) sequence [3–10]. The sedimentary textures and chemistry of the units above (Chenapau member) and below (Catrimani and Contigo members) the AMB are very similar but differ in mineralogy (Mg-sulfate in Catrimani [11] and siderite+Mg-sulfate in Chenapau [12]).
