Israel/Central Coastal Plain
Iron Age I
—
The clay is carbonatic, yellowish to tan in PPL, rich with poorly-sorted carbonate micritic limestone, with many very poorly-sorted spherical and rounded iron rich minerals (up to 50µm). The matrix is very rich in microfossils, including planktonic foraminifera such as Globigerinella. In some cases the foraminifera are filled or surrounded with iron rich minerals. The fabric also includes benthonic foraminifera, such as Brizalina and coralline algae such as Amphiroa and Bryozoa . The inclusions consist of sub-angular to angular quartz (5-15% 50-150µm), limestone (~5% up to 200µm) and chert in different levels of erosion.
