Stratigraphy
Formation:Maevarano Member:Lac Kinkony
Stratigraphic resolution:bed
Stratigraphy comments: The stratotype of the Lac Kinkony Member (at a site designated “Kinkony 1”) is located w2.5 km to the northeast of the village of Analalava, on the western edge of the escarpment
Lithology and environment
Primary lithology:gray silty claystone
Secondary lithology:white calcareous sandstone
Lithology description: Siltstone facies pass up-section to distinctive white sandstones packed with dolomitic mud matrix that exhibit rhythmic clay drapes, flaser and wavy bedding, and oppositelyoriented ripples developed on the toes of larger foresets. Thin flat interbeds of microgranular dolostone and claystone comprise the uppermost facies of the Lac Kinkony Member, and a laterally traceable ravinement bed mantled by cobbles of rounded dolostone marks the contact with the superjacent Berivotra Formation
Environment:open shallow subtidal
Geology comments: Siliciclastic and carbonate tidal flats dissected by tidally-influenced rivers
