Complex interplay between depositional and petrophysical environments in Holocene tidal carbonates (Al Ruwais, Qatar)

Abstract: Carbonate rocks can be classified in terms of those properties relating to the pore system of lithified sediments, so‐called ‘petrophysical rock types’, or ‘depositional rock types’ which are categorized based on characteristics directly reflecting their original depositional environment. Whereas petrophysical rock types are typically used to identify and distribute rock bodies within a reservoir with similar flow characteristics, depositional rock types ignore pore types and capture sedimentary structures, li… Show more

“…This lack of congruency partly arises from the low fine fraction content on the wave and tide swept sand apron. A similar discrepancy between sedimentary texture and environmental facies has been described for other mud lean settings such as in the Holocene tidal carbonates from offshore Al Ruwais in Qatar (Purkis et al., ). Despite the absence of a direct correspondence between sedimentary and environmental facies in the sand apron, the satellite‐derived environmental facies map allow some predictions about the grain‐size distribution.…”

“…This depositional setting includes the ''Trucial Coast'' of northern Oman and the United Arab Emirates, which hosts the ''Great Pearl Bank,'' and is considered an important modern example of a homoclinal carbonate-ramp setting (Read 1982). In the western part of this evaporative warm-water domain, the coastal waters of Qatar host photozoan carbonate deposits (Purser and Evans 1973;Shinn 1973;Billeaud et al 2014;Purkis et al 2017) that include localized ooid bodies (Loreau and Purser 1973).…”

“…Acropora was previously common around much of Qatar (Emara, El‐Samra, El‐Debb, & Ahmed, ; Shinn, ) and in the Gulf of Salwah (Sheppard, ), however, since 2004, living A. downingi occur at only two offshore locations (Halul, Umm al Arshan). The formerly Acopora ‐covered northern tip of the peninsula (Kinsman, ; Shinn, ) and its east coast today harbor only occasional fringes of merulinids and poritids (Burt, Smith, Warren, & Dupont, ; Purkis et al., ). On offshore banks (Fasht Adhm, Abu Kafan, Halat Dalma), Acropora ‐dominated coral cover declined from ~60% in 1985 to zero by 2007 (C.R.C.…”
