Phosphorite and Limestone, Two Independent End-Member ...

2000-1-1 · Calcium carbonate is known to be one of the sedimentary materials occuring with phosphorite in many of the phosphorite deposits. This relationship has been described for various geological periods and at various scales: mineable phosphorite alternating with barren carbonate; calcific or more often dolomitic phosphorite alternating with phosphatic dolomite or limestone.

The basal 7-12 m thick section consists of chalk, marly limestone, chalky limestone and the interval of phosphorite concretions (10-30 cm). The latter package can be traced to different parts of the study area and has a broad distribution in central Jordan. The presence of these concretions is not consistent and they disappear in some localities.
