GEOL 751 Lecture 5: Shark Bay Carbonates
Shark Bay is an important analogue for ancient
carbonates Open marine carbonate bioclastic bank margins form
linear lens shaped continuous bodies along strike
Carbonate sill & hypersaline coastal terraces form box
shaped continuous linear bodies along strike
Metahaline cementation favors stromatolite heads, ooids,
intertidal capillary crusts, & cemented lagoon floors
Evaporite/Carbonate couplets may be the product of seasurface depression below a barrier margin that leaks
