Model of a virtual "shallowing upward" metric sequence observed on carbonate platforms all along the south tethyan margin (about 10.000km) during the Liassic. (Micro)fossils are identical from the Maghreb till Oman and furtheron.
Virtual metric "shallowing upward sequence" observed all along (more than 10,000 km) the south Tethyan margin during middle Liassic times. The (micro)fossils are identical till Oman and beyond. Sequence stratigraphy of carbonate platforms
[2] [1] Most parasequences show a shallowing upward, [3] which is sometimes also included into the definition. [4] Schematic graphic log showing facies successions in common types of clastic parasequences Schematic graphic log showing facies successions in common types of carbonate parasequences
Shallowing upward sequence with lower lagoonal marine, then intertidal algal laminations and top cycle an hurricane breccia in a dolomitic matrix. The Aganane Formation, is a thick carbonate-dominated sequence, reaching up to 600 meters in thickness.
A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.
Hardie and his students and colleagues also studied cyclic sedimentation, confirming that platform carbonates of the Middle Triassic (Anisian-Ladinian) of the Latemar buildup consist of a vertical stack of over 500 thin (ave. thickness 0.6-0.85m) shallowing-upward depositional cycles that record high frequency eustatic sea level oscillations in ...
Hims compiled a list of the top 25 U.S. counties for dating based on the number of single households, median age, restaurant volume per capita, and proximity to a major metropolitan area.
Sequence stratigraphy is a branch of geology, specifically a branch of stratigraphy, that attempts to discern and understand historic geology through time by ...
