Controls on development and diversity of Early Archean stromatolites [PDF]

open access: yes, 2009
The ≈3,450-million-year-old Strelley Pool Formation in Western Australia contains a reef-like assembly of laminated sedimentary accretion structures (stromatolites) that have macroscale characteristics suggestive of biological influence.

Dolomite genesis and reservoir-cap rock assemblage in carbonate-evaporite paragenesis system

open access: yesPetroleum Exploration and Development, 2019
Regarding to the problem on the reservoir-cap rock assemblage evaluation in the carbonate-evaporite paragenesis system, this study examined the dolomite and reservoirs genesis and the characteristics of reservoir-cap rock assemblage.

Frictional Instabilities and Carbonation of Basalts Triggered by Injection of Pressurized H2O- and CO2- Rich Fluids [PDF]

open access: yes, 2018
The safe application of geological carbon storage depends also on the seismic hazard associated with fluid injection. In this regard, we performed friction experiments using a rotary shear apparatus on precut basalts with variable degree of hydrothermal ...

Effect of Dolomite Addition on The Performance of Palm Oil Mill Fly Ash for Methylene Blue Adsorption

open access: yesIndonesian Journal of Chemical Analysis, 2023
The use of palm oil mill fly ash (FA) as a low-cost adsorbent is one of the solutions for handling FA waste. In this study, the addition of dolomite is expected to improve the adsorbent performance. The aim of this study was to investigate the optimum FA-

Fluid evolution in CM carbonaceous chondrites tracked through the oxygen isotopic compositions of carbonates [PDF]

open access: yes, 2017
The oxygen isotopic compositions of calcite grains in four CM carbonaceous chondrites have been determined by NanoSIMS, and results reveal that aqueous solutions evolved in a similar manner between parent body regions with different intensities of ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Pore Types and Dolomite Reservoir Genesis of the Fifth Member of the Ordovician Majiagou Formation in the Central and Eastern Ordos Basin

open access: yesApplied Sciences
The Ordovician dolomite in the Ordos Basin is an important natural gas reservoir. Exploring dolomite genesis and the factors influencing reservoir characteristics is essential for deep carbonate rock exploration.

Recycling of Spent Cathode Carbon from Aluminum Electrolysis: Detoxification Approaches, Resource Utilization, and Environmental Perspectives

open access: yesChemElectroChem, EarlyView.
This review outlines the recycling of spent cathode carbon from aluminum electrolysis. Detoxification strategies, including molten salt roasting and ultrasonic‐assisted leaching, are depicted as effective approaches for removing hazardous components. The recovered carbon is further directed toward resource utilization, such as in lithium‐ and carbon ...
