Clinoform morphology
WebMay 3, 2024 · The limited vertical expression of the shoreline clinoform and the lateral extent of the subaqueous clinoform hamper the identification of compound clinoforms in the rock record. The modern Colorado River Delta, in Baja California, Mexico, is tide-dominated and exhibits a compound clinoform; we use this delta as an analog to guide our ... WebThe mud wedge has a clinoform morphology with gently dipping topset, steeply dipping foreset, and gently dipping bottomset beds. 14C age dates indicate the clinoform began to form around 7000 yrs BP after sea-level reached the middle Holocene Highstand stage and decelerated to it’s present position.

A shallow delta front clinoform extends along the entire delta coast from the shoreline to the 10-25 m water depth. A mid-shelf clinoform developed probably as a prodelta clinoform between ∼30 and 90 m water depth. The advanced position of the mid-shelf clinoform east of the ...
WebHowever, interpretation of paralic deposits in the stratigraphic record has tended to ignore the double-clinoform morphology of deltas that develops the greatly extended subaqueous portions of wave- and tide- dominated deltas as well as a remarkable and significant spatial separation between shoreline and subaqueous delta- front rollovers.
