Journal Article
Genesis of Liassic shallow and deep water rhythms, central High Atlas Mountains, Morocco Available to Purchase
Journal: Journal of Sedimentary Research
Publisher: SEPM Society for Sedimentary Geology
Published: 01 March 1977
Journal of Sedimentary Research (1977) 47 (1): 120–128.
...I. Evans; C. G. S. C. Kendall; J. C. Butler Abstract During Liassic time, carbonate sediments were deposited in a northeast-southwest oriented marine trough that now forms part of the High Atlas mountains, Morocco. Shelf and deep basin deposits of this trough consist of marls, micrites and marly...
Journal Article
Shelf basin sedimentation; mixing and diagenesis of pelagic and clastic Turonian carbonates, Israel Available to Purchase
Journal: Journal of Sedimentary Research
Publisher: SEPM Society for Sedimentary Geology
Published: 01 March 1977
Journal of Sedimentary Research (1977) 47 (1): 382–391.
...A. Bein Abstract The Turonian shelf edge, which delimited a large carbonate shelf platform, closely corresponds to the present-day shoreline of Israel. A NE-trending shelf basin, over 30 km long and about 5-10 km wide, had been cut into the shelf rocks during the regression which terminated...
