Influence of different rock-soil fabrics on carbonate weathering carbon sink flux in karst regions

地质科技通报, 2022
The karst areas in southern China are characterized by a high rock exposure ratio and shallow and unevenly distributed soil layers.How this special geotechnical fabric affects the hydrological process is of great significance for the accurate estimation ...

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

, 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.

An Integrated Approach for Formation Micro-Image Rock Typing Based on Petrography Data: A Case Study in Shallow Marine Carbonates

Geosciences, 2021
Core rock-typing (RT) is commonly used for creating geologically reliable models of porous media in carbonate reservoirs. This approach is more advanced than the traditional porosity–permeability relationship and is based on the division of carbonate ...

Dynamic pore-scale reservoir-condition imaging of reaction in carbonates using synchrotron fast tomography [PDF]

, 2015
Synchrotron fast tomography was used to dynamically image dissolution of limestone in the presence of CO2-saturated brine at reservoir conditions. 100 scans were taken at a 6.1 µm resolution over a period of 2 hours.

EXPANSION BRECCIAS IN CARBONATE ROCKS

Geological Society of America Abstracts with Programs, 2016
We describe breccias in limestone or dolomite that appear to have been expanded with no shearing. In examples from the Lower Cretaceous Maiolica pelagic limestone in the Apennines and the Mississippian Madison Limestone in Wyoming, they are made of angular carbonate fragments from

Changes of Physical and Mechanical Properties of Coral Reef Limestone under CO₂–Seawater–Rock Interaction

Applied Sciences, 2022
Large amounts of anthropogenic CO2 in the atmosphere are taken up when the ocean alters the seawater carbonate system, which could have a significant impact on carbonate-rich sediments.
