Abstract

Carbonaceous sediments of Early to Middle Cretaceous age are common to sedimentary sequences of the Tethys region now exposed in Alpine Mountain belts. Barremian through Albian pelagic sediments, relatively rich in organic carbon (Corg) were deposited on shallow pelagic plateaus, slopes and on oceanic crust along the S margin of Tethys. Rhythmically interbedded, bioturbated pelagic carbonates and dark, laminated carbonaceous shales suggest conditions of periodic anoxia in deep water masses and fluctuating productivity or dissolution of carbonate within a period of 20 000 to 50 000 yr.-from Authors
