• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Dam Formation, Burdigalian (20.4 - 16.0 Ma)

• Lower Dam Formation. In the United Arab Emirates, the Formation is demonstrably Early Miocene (Burdigalian) as shown by strontium isotope dating (Peebles, 1999), and an Early Miocene age is also indicated in Saudi Arabia (Greenwood, 1987; Whybrow et al., 1987; Otero and Gayet, 2001). A Borelis melo-bearing limestone/shale is common in many parts of the Arabian Plate (including the Red Sea margin) and has been given a Burdigalian age (Sharland et al., 2001). The Formation represents a distinct flooding event that culminated in MFS Ng20 (mid-Burdigalian) of Sharland et al. (2001), whereas the later flooding event of MFS Ng30 (Middle Miocene, late Langhian) occurred within the Jeribe Formation of Saudi Arabia. An Early Miocene (Burdigalian) age is therefore assigned to the Dam Formation (Al-Saad & Ibrahim, 2002).
