Earliest Triassic microbialites in the South China Block and other areas; controls on their growth and distribution [PDF]

open access: yes, 2007
Earliest Triassic microbialites (ETMs) and inorganic carbonate crystal fans formed after the end-Permian mass extinction (ca. 251.4 Ma) within the basal Triassic Hindeodus parvus conodont zone.

Lithostratigraphy and depositional episodes of the Oligocene carbonate-rich Tikorangi Formation, Taranaki Basin, New Zealand [PDF]

open access: yes, 2003
The subsurface Oligocene Tikorangi Formation is a unique and important oil producer in the onshore Waihapa-Ngaere Field, Taranaki Basin, being the only carbonate and fracture-producing reservoir within the basin. Core sample data from seven onshore wells

DEPOSITIONAL ARCHITECTURE, FACIES CHARACTER AND GEOCHEMICAL SIGNATURE OF THE TIVOLI TRAVERTINES (PLEISTOCENE, ACQUE ALBULE BASIN, CENTRAL ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
Facies character, diagenesis, geochemical signature, porosity, permeability, and geometry of the upper Pleistocene Tivoli travertines were investigated integrating information from six borehole cores, drilled along a 3 km N-S transect, and quarry faces ...

Quantitative Analysis of Thin Section using Frequency Measurement (Point Counting), a Case Study on Limestone of The Rajamandala Formation, Cikamuning, West Java, Indonesia

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology
The description of thin sections observations has traditionally relied on the visual comparison method, often using a visual comparison chart. However, this method has interpretative limitations, as readings can vary between individuals, and the values ...

An integrated analysis (microfacies and ichnology) of a shallow carbonate-platform succession: upper Aptian, Lower Cretaceous, Betic Cordillera

open access: yes, 2017
Four lithofacies and 12 microfacies types recognized in an upper Aptian section in the Sierra de Bedmar-Jódar (Prebetic of Jaén) represent shallow lagoonal environments (marl and marly limestone) and sand bars that delimited the lagoon.

New insights into the development of the Late Jurassic Reuchenette Formation of NW Switzerland (late Oxfordian to late Kimmeridgian, Jura Mountains) [PDF]

open access: yes, 2004
In the Ajoie-Region, seven in situ collected species of ammonites helped to establish a new biostratigraphical an dlithological frame for the platform sediments of the Reuchenette Formation, i.e.

Reconstruction of palaeoflow and depositional dynamics from the Merjasec unroofed cave, Laze Plain (central Slovenia)

open access: yesActa Geographica Slovenica
Sparsely preserved unroofed cave deposits are ancient remains of cave systems. The Merjasec unroofed cave is a perfect example of poorly preserved cave deposits where conventional sedimentological study revealed a greater potential for the reconstruction

Sedimentary hints of seismic reflectors into an oolithic carbonate analogue reservoir study case on the “Oolithe Blanche” (Burgundy, France)

open access: yesBSGF - Earth Sciences Bulletin
Although 3D and even 4D seismic imaging have advanced significantly, some acoustic patterns in carbonate reservoirs remain poorly understood. Diagenetic effects are still largely overlooked in interpreting reflectors within these complex sedimentary ...
