Peer-reviewed Mars carbonate study registered with Crossref

The supplied record newly identifies a peer-reviewed journal article titled “VNIR–mid-IR spectral signatures of abiotic and biogenic mixed-cation carbonates: implications for carbonate detection and biosignature assessment on Mars” [1]. The article is associated with the journal Icarus and has the DOI 10.1016/j.icarus.2026.117262 [1]. Its stated subject is the comparison of visible/near-infrared and mid-infrared spectral signatures from abiotic and biogenic mixed-cation carbonates, with implications for detecting carbonates and assessing possible biosignatures on Mars [1]. The source establishes the publication’s registration, peer-reviewed status, title, DOI, and research scope, but it provides no experimental methods, samples, measurements, results, statistical analysis, or evidence that any Martian carbonate is biological [1].
