Matmor Formation

The Iraq Petroleum Company originally described the Jurassic sequence in Hamakhtesh Hagadol of Israel in the 1930s (Hudson, 1958). These findings were later described and published by Blake (1935). Shaw (1947) published a limited summary of the stratigraphy. Hudson (1958) later subdivided the rocks into the Callovian, Divesian, Argovian, Sequanim biostratigraphic stages. In 1963, Goldberg subdivided the section into the Zohar, Kidod and Be'er Sheva Formations. Goldberg (1963) further divided the Zohar Formation into the Ziyya and Madsus members. In 1966, Mayac dated the Callovian and what appeared to be the Lower Oxfordian stages with forams (Mayac, 1966, in Hirsch and Roded, 1996). Further biostratigraphic work by Hirsch et al. (1998) and Grossowicz et al. (2000) show that the Matmor Formation is entirely Late Callovian.
