Total organic carbon contents (Al Wajh carbonate platform lagoon)

open access: yes, 2022
The Al Wajh platform - located in the Arabian-African desert belt - is a large land-attached carbonate platform in the Red Sea. In order to analyze total organic carbon (TOC) in Al Wajh lagoon, sediments were dried at 40°C and powdered by hand in a ...

Survey of the diagenesis process and effect these process on reservoir quality of the Kangan formation in South Pars Field [PDF]

open access: yes, 2009
Kangan and Upper Dalan formations are forming reservoir sequence of the South Pars field. Litology of the kangan formation is carbonate and (limestone and dolomite with anhydrite intervals), so digenetic processes were very active in this formation and ...

Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating [PDF]

open access: yes, 2009
Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates ...

Pliocene Te Aute limestones, New Zealand: Expanding concepts for cool-water shelf carbonates [PDF]

open access: yes, 2003
Acceptance of a spectrum of warm- through cold-water shallow-marine carbonate facies has become of fundamental importance for correctly interpreting the origin and significance of all ancient platform limestones.

Variability and control of the surface ocean carbonate system observed from ships of opportunity

open access: yes, 2014
The surface ocean plays an important role in the marine carbon cycle linking the atmosphere and the deep ocean. There are substantial variations in the surface ocean carbonate system in different environments and on various time scales, resulting from ...

Lateral discrepancies of cycle patterns in the Latemàr, Triassic, Italian Dolomites [PDF]

open access: yes
The well-known cyclic carbonate succession of the Middle Triassic Latemàr Massif in the Italian Dolomites reveals significant lateral variability in cycle numbers in platform-interior strata.

Laboratory Models of Microbial Biosignatures in Carbonate Rocks [PDF]

open access: yes, 2005
Enigmatically shaped laminated carbonate rocks called stromatolites dominated shallow marine environments for the first 80% of Earth’s history, and are potentially the oldest macrofossils.

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: A synthesis and review [PDF]

open access: yes, 1996
The stable oxygen isotope composition (δ18O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (δ13C) reflects the source of CO2 for ...
