Limestone rock formation.
Perhaps before the metamorphism, this rock formed in the deep ocean, where silt and clay particles and small pieces of shelly debris accumulated. Then, after the rock had lithified, becoming solid rock of limestone interbedded with shale, it experienced metamorphism, likely associated with continental collision.
lagoon which allowed for the formation of salts and other evaporite minerals (like anhydrite and gypsum) from Paleocene to middle Eocene times.
