Lithology and environment
Primary lithology: | sandstone |
Secondary lithology: | mudstone |
Lithology description: Unit 1: "A thick succession of sandstones and mudstones, with intercalations of carbonate and evaporitic rocks" "fine-grained sandy deposits with subordinate muddy layers and two thin evaporitic levels" and Unit 2: "a thick succession of siltstone and mudstone deposits with thin intercalations of ostracod-rich limestones and sandy levels" | |
Environment: | terrestrial indet. |
Geology comments: "Interpreted as reflecting brackish lagoonal and supratidal environments, associated with aeolian sands (dunes) and deposits of ephemeral rivers" |
