Unlocking paleo- environmental information from Early Cretaceous shelf sediments in the Helvetic Alps: stratigraphy is the key! Swiss J. Geosci. 100, 349-369
p.12: The lower part of the Grünten Member overlying the Rohrbachstein Bed consists of a quartz- and glauconite-containing marl or marly carbonate, which is rich in echinodermal debris and reworked and partly micritized Schrattenkalk extraclasts. This unit is limited to the southern areas within
the Helvetic realm and reaches a maximum thickness of about 15 m. In the Rawil area, the lower part of the Grünten Member is covered by a thin, nodular glauconite- and phosphate-containing layer, in which sparse phosphate particles occur [Plaine Morte Bed].
