Taqiye marl is the name used in Israel for a marine formation widespread throughout the Mediterranean.
Taqiye formation is of Paleogene age and characterized by a light, highly calcareous marl, rich in foraminifera (Goren 1995: 302). When fired in an oxidizing atmosphere, the clay receives a light tan color in thin section. The matrix is usually rich in fine, fibrous carbonate crystals and sometimes exhibits a weak optical orientation (length fast). Well-sorted, sparsely distributed silty quartz appears in many cases. The distribution of the Taqiye formation is widespread. The Taqiye formation is exposed in the northern and central Negev, in the Judaean Desert and along the western slopes of the Judaean-Samarian anticline. This formation is almost constant in its stratigraphic position and even in details of its composition. Equivalent beds appear also in Egypt (Esna shales) and even in Morocco and Turkey. Therefore, it cannot be used for a definitive provenance distinction. In many cases the potters added to the marl powdered Terra Rossa to improve the ferocity of the clay.
