Petrography, chemistry and genesis of phosphorite concretions in the Eocene Umm Rijam Chert limestone Formation, Ma'an area, south Jordan
K Tarawneh, K Moumani - Journal of Asian Earth Sciences, 2006 - Elsevier
Phosphorite concretions are recorded for the first time within the lower part of the Umm
Rijam Chert Limestone Formation (Eocene) in the Ma'an area, southern Jordan. The
phosphorite concretions are typically hosted and encountered as individual layer in
moderately lithified sediments of marl, chalk and chalky marl. The phosphorite concretions
are present in thin layer (10–30cm thick). They are localized on a hardground surface that
formed as a result of cementation of soft ground by bioclastic materials. Light grey and …
