--- name: geology description: Use when targeting Geology (GSA) or deciding whether a short, high-impact geoscience research letter fits this venue. Encodes the journal's broad-significance-in-tight-length fit, the novelty and rapid-communication bar, GSA house style, official-submission re-check, and desk-reject heuristics. --- # Geology (geology) ## Journal positioning Geology is the Geological Society of America's flagship outlet for **short, high-impact research letters across the geosciences**. The defining expectation is a contribution that is at once **novel, broadly significant, and concisely framed for a wide geoscience audience** within a tight length limit — a result that changes how a broad readership thinks about an earth process, delivered rapidly. The constraint is as much editorial as scientific: the science must be both important and compressible to a few pages, with the significance legible to non-specialists. A thorough but incremental study, a regional report without wide implications, or a paper that genuinely needs full article length to make its case is a poor fit, regardless of quality. This skill is a **fit / venue-selection / re-framing** tool. It does not replace the journal's current author guidance. Before submitting, re-check the live Geology / GSA author instructions and data policy. ## When to trigger - The author names Geology and wants a fit/framing check for a short, high-significance geoscience result. - A finding with wide implications must be compressed into a tight, broadly legible letter rather than a full-length article. - The author is choosing between Geology (short GSA letter) and `earth-and-planetary-science-letters` (longer quantitative process article). - The author needs Geology's broad-significance-in-tight-length bar and rapid-communication expectations. ## Scope & topic fit - Tectonics, structural geology, and geodynamics with implications beyond one orogen or basin. - Sedimentology, stratigraphy, and Earth-surface processes that reframe a depositional or landscape model. - Geochronology and thermochronology that newly constrain rates or timing of broad interest. - Petrology, volcanology, and geochemistry where a result shifts a process understanding. - Paleontology, paleoclimate, and paleobiology when a finding has wide-reaching significance. - Any geoscience subfield where the contribution is novel and the implications travel beyond the immediate community. ## Method & evidence bar - The result must be **novel and broadly significant**, and that significance must be demonstrable to a wide geoscience audience, not just asserted. - Evidence must be sufficient and rigorous despite brevity: methods, data, and uncertainty must still be defensible within the compressed format. - A single, sharp claim should be supported cleanly; the letter should not over-reach beyond what the compact dataset can bear. - Chronology, geochemistry, and modeling claims require the same standards (standards/ reference materials, calibration, sensitivity) as longer venues, reported efficiently. - Alternative interpretations must be acknowledged and the preferred one justified, even in short form. - Supporting data, analytical detail, and code belong in a GSA data repository / supplement with a persistent identifier so the compact main text remains reproducible. ## Structure & house style - GSA short-letter format with a strict length limit; the science must fit, not be crammed — re-check current length, figure, and reference limits on the live guide. - The opening must state the broad significance immediately; a slow regional setup wastes the format and the reader. - Figures must be few, self-explanatory, and decisive; each one must earn its place in the tight budget. - Methods and extended data move to the GSA data repository / supplemental material, with the main text carrying only the load-bearing evidence. - A data-availability statement and repository deposition are expected; the supplement must support reproducibility of the compact result. ## Official-submission checklist - Before giving submission-ready advice, read `../../resources/source-basis.md` and `../../resources/official-source-map.md`; start from the GSA/Geology anchors, then cite the current Geology page you checked. - Search the live site for "Geology GSA author guidelines" and follow the current GSA version. - Re-check the **strict length, figure, and reference limits** and the abstract/format expectations specific to short letters. - Confirm the **GSA data-repository / supplemental-material policy** and deposit supporting data with a persistent identifier. - Re-check competing-interests, funding, author-contribution, AI-use disclosure, and open-access terms. - If the live official instructions conflict with this skill, the official instructions win. ## Pre-submission self-check - [ ] The result is novel and its significance is legible to a broad geoscience audience. - [ ] The science genuinely fits the short-letter length without over-reaching. - [ ] Methods, data, and uncertainty remain defensible within the compressed format. - [ ] Figures are few, decisive, and self-explanatory. - [ ] Extended methods/data are in the GSA repository/supplement with an identifier. - [ ] Alternative interpretations are acknowledged and the preferred one justified. ## Common desk-reject triggers - A thorough but incremental result without wide implications for the format. - A regional study whose significance does not travel beyond the immediate community. - A paper that genuinely requires full article length and is crammed into the limit. - Brevity used to hide thin evidence, missing uncertainty, or unaddressed alternatives. - Overstated significance not supported by the compact dataset. - Missing GSA data-repository deposition where required. ## Re-routing decision - A longer, fully quantitative process/geochemistry article → `earth-and-planetary-science-letters`. - Highest-impact geoscience breakthrough for a general audience → `nature-geoscience`. - Broad earth/environment open-access framing at standard length → `communications-earth-and-environment`. - A short geophysical result better suited to an AGU letter → `geophysical-research-letters`. - A documented dataset rather than an interpretation is the product → `earth-system-science-data`. ## Output format ```text [Fit] High / Medium / Low (one-line reason) [Target] Geology (GSA) [Topic tags] <2–3 closest geoscience topics> [Broad significance] [Fits-the-format] [Top risk] [Official items to re-check] [Re-route suggestion] ```
