Two-phase diagenesis of Quaternary carbonates, Arabian Gulf: Insights from {delta}{sup 13}C and {delta}{sup 18}O data
- Univ. of Houston, TX (United States). Dept. of Geosciences
Diagenesis of the top 25 m of Quaternary sediment and rock samples from the shallow subsurface under the nearshore part of the Arabian Gulf is the primary subject of this study. During the last forty years, since this area was recognized as a site of extensive carbonate deposition, the origin, distribution, and dolomitization of modern sediments in the Arabian Gulf region have been intensively studied. However, few geoscientists have studied the Quaternary deposits below the top few meters of accumulation. As a complement to previous work, this study is primarily concerned with the diagenesis of aragonitic and high-magnesium calcitic sediments to sediments composing a low-magnesium calcitic facies. The samples studied, intercalated carbonate and siliciclastic sediments and rocks, were collected from a series of borings offshore of Al Jubayl, Saudi Arabia. The lowermost part of the section is predominantly Pleistocene dolomite. The middle part is composed of intercalated low-magnesium calcite and siliciclastics and is herein interpreted as Pleistocene.
