The chromian marbles of Kittilä, Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1978
The volcano-sedimentary rock association at Kittilä is characterized in many places by the presence of green-colored fuchsite-bearing ferroan dolomite-quartz rocks, locally called chromian marbles.

Pore Type and Porosity Distribution of Carbonate Reservoir Based on 3D Seismic Inversion in “P” Field Salawati Basin [PDF]

open access: yesE3S Web of Conferences, 2019
Overall, carbonate rock has complex and more heterogeneous physical characteristic, compared to siliciclastic sedimentary rock. One parameter, which distinguishes carbonate rock and siliciclastic is pore structure/pore type.

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

open access: yesGeosciences, 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 ...
