Figure 9: Paleofacies of the Middle Jurassic. This time period spanned the deposition of the Izhara, Araej, and Dhruma formations, and their regional equivalents [MFS J20 to intra-J40]. These sediments were deposited in an open-marine environment, as the Arabian Plate now had passive margins to Neo-Tethys to the northeast and north.
