Recycled carbonates elevate the electrical conductivity of deeply ...
网页2023年7月29日 — We propose that carbonate-silicate cations exchange can alter the chemical composition of recycled carbonates, potentially impacting their stability and reducing the solidus temperature of ...
Hybrid Carbonates: in situ abiotic, microbial and skeletal co ...
网页2020年9月1日 — Plots of Hybrid Carbonate composition in time and space reveal complex ‘backtracking’ and ‘looping’ patterns that reflect changes in environmental conditions and biological processes of carbonate production.
Early Cambrian evaporite deposits in the North China Craton and …
网页2023年2月1日 — The widespread Cambrian strata in the NCC principally consist of mixed siliciclastic-carbonate deposits in the shallow-water platform facies (Zhu et al., 2021). The well-developed middle and upper Cambrian strata in …
Rare earth element geochemistry of carbonates as a proxy for …
网页2021年7月15日 — The rare earth elements and yttrium (REY) can enter carbonate lattices by replacing cations, which can be used to reconstruct the history of carbonate…
Carbonate Regeneration Using a Membrane Electrochemical Cell …
网页2022年11月28日 — We propose a new method of CO 2 regeneration from a carbonate capture solution (K 2 CO 3) through a driven anion exchange membrane (AEM) cell depolarized with hydrogen. This design overcomes the limitations in efficiency and current density that arise in direct gas phase separation of <1% concentration CO 2 using AEMs.
High carbonate ion conductance of a robust PiperION membrane …
网页A poly(aryl piperidinium)-based anion exchange membrane (PiperION) with high carbonate conductance is employed for CO2 electrolysis to CO in conjunction with a tailored electrolyzer cell structure. This combination results in unprecedentedly high partial current densities in zero-gap cells (jCO > 1.0 A cm−2) Recent Open Access Articles
The co-relationship of marine carbonates and evaporites: a
网页2020年10月27日 — Among the previous researches, there are mainly two types of relationships between carbonates and evaporites in marine settings according to the paleogeographic setting: (1) large semi-restricted basins rimmed by carbonate platforms; (2) evaporitic basins and lagoons located behind carbonate rims or barriers facing the open sea (Tucker 1991 ...
Different forms of carbonate platforms within a shallow …
网页The types of carbonate reservoir pore spaces are complex and diverse. Primary pores are mainly biological cavity pores with small pore size, mostly isolated individuals, poor connectivity, and ...
A Shorthand Notation for Carbonate Facies—Dunham Revisited
网页Carbonate facies can be described in a concise format that reads like an algebraic equation: CARBONATE FACIES = (LITHIC DESCRIPTOR) (COMPOSITION) (TEXTURE) ± REMARK. Lithic descriptors are portrayed by symbols for sedimentary structures, admixtures of argillaceous or arenaceous material, …
Classification of Carbonates | SpringerLink
网页The wide range of percentage of mud matrix that a carbonate may have and still be termed a packstone by Dunham sometimes reduces the utility of this classification. Embry has modified the classification of Dunham and Klovan (1971) to include coarse grained carbonates (above figure).
