SEQUENCE STRATIGRAPHY OF THE EOCENE ROCKS IN QATAR PENINSULA, ARABIAN GULF

The Eocene sedimentary succession of Qatar is subdivided, from older to younger, into the Umm er
Radhuma, Rus and Dammam formations. This Eocene succession forms a part of the Arabian Plate
Megasequence (AP10) and has been partitioned into two sequences; Pg 10 and Pg 20 respectively. The
lithofacies and biofacies studies of this Eocene megasequence in Qatar have enabled the identification and
interpretation of the depositional settings and faunal elements of the different Eocene units. The lower Pg
10 sequence is represented by the shallow water Umm Er Radhuma and Rus formations, and is subdivided
into a lower transgressive and an upper highstand systems tracts, while the upper Pg 20 sequence is
represented by the shallow water Dammam Formation, and is subdivided into a transgressive and a
highstand systems tracts. These two sequences are bounded by three major sequence boundaries.
