Earth and Planetary Science Letters (earth-and-planetary-science-letters)
Journal positioning
Earth and Planetary Science Letters (EPSL), published by Elsevier, is a broad-interest
journal for quantitative research on the physical and chemical processes of the Earth and
other planets. The defining expectation is a process-oriented, quantitatively rigorous
advance — in geochemistry, geophysics, geodynamics, petrology and mineral physics, planetary
processes, or paleoclimate/paleoceanography proxy science — that is significant to a wide
earth- and planetary-science readership rather than to one specialty alone. Despite the
"Letters" name, EPSL favors complete, self-contained articles in which the data, modeling,
and interpretation jointly support a generalizable mechanism; a purely descriptive regional
report, a method note with no process payoff, or a result of interest only to a narrow
sub-field is a weak fit. 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
EPSL / Elsevier author instructions and data policy.
When to trigger
- The author names EPSL and wants a fit/framing check for a quantitative solid-earth or
planetary-science paper.
- A regional geochemical or geophysical study must be re-framed into a transferable
process or mechanism of broad interest.
- The author is choosing between EPSL (longer quantitative process article) and
geology
(short, high-immediacy GSA letter).
- The author needs EPSL's broad-interest significance bar and quantitative evidence
expectations.
Scope & topic fit
- Geochemistry and isotope geochemistry: tracers, dating, and elemental/isotopic systems
constraining earth and planetary processes.
- Geophysics and geodynamics: seismology, mantle dynamics, tectonics, gravity/magnetics, and
lithosphere/deep-earth structure and evolution.
- Petrology, mineral physics, and high-pressure/high-temperature experiments bearing on
planetary interiors and differentiation.
- Surface and planetary processes: volcanism, impacts, planetary evolution, and comparative
planetology with quantitative constraints.
- Paleoclimate and paleoceanography proxy records and their calibration, when the
contribution is a mechanism or a generalizable proxy advance.
- Cross-cutting modeling that links observations to a quantitative earth/planetary process.
Method & evidence bar
- The contribution must be a quantitative, generalizable process or mechanism, not a
catalogue of measurements from one locality.
- Geochemical/isotopic data require documented analytical methods, standards, reference
materials, blanks, and full uncertainty propagation.
- Geophysical and modeling results need stated assumptions, resolution/sensitivity tests,
and evaluation against independent observations.
- Proxy and paleo reconstructions require explicit calibration, age-model treatment, and
uncertainty, with alternative interpretations considered.
- Claims of broad significance must connect the local result to a wider earth/planetary
process; mechanism should be argued, not merely correlated.
- Underlying data (and code where used) should be deposited in a FAIR repository or
supplied as machine-readable tables per Elsevier/research-data policy.
Structure & house style
- Elsevier article format; EPSL is article-length and self-contained despite the "Letters"
name — re-check current article types and length on the live guide.
- The introduction must state the earth/planetary-science gap and the broad-interest
contribution, not merely describe a field area or sample set.
- Figures should be quantitative and load-bearing (data with uncertainty, model–data
comparisons, maps/cross-sections, isotope/phase diagrams) and support the mechanism.
- Methods and a data-availability statement must let a reader reproduce the central result;
analytical protocols and data tables belong in the paper or supplement.
- Interpretation should be proportionate to the data and explicitly bounded by stated
uncertainties.
Official-submission checklist
- Before giving submission-ready advice, read
../../resources/source-basis.md and
../../resources/official-source-map.md; start from the Elsevier/EPSL anchors, then cite
the current EPSL page you checked.
- Search the live site for "Earth and Planetary Science Letters guide for authors" and
follow the current Elsevier version.
- Re-check article types, abstract/format expectations, and length/figure expectations.
- Confirm the research-data policy: deposit data/code in a FAIR repository or provide
machine-readable data tables, and cite them appropriately.
- Re-check competing-interests, funding, author-contribution, CRediT, AI-use disclosure, and
open-access terms.
- If the live official instructions conflict with this skill, the official instructions
win.
Pre-submission self-check
Common desk-reject triggers
- A descriptive regional report with no transferable process or broad-interest significance.
- Geochemical data without standards, reference materials, or uncertainty propagation.
- Model or geophysical results lacking sensitivity tests or independent evaluation.
- Proxy/paleo claims without calibration, age-model treatment, or uncertainty.
- Interpretation that outruns the data or ignores plausible alternatives.
- Scope too narrow or too applied for EPSL's broad earth/planetary readership.
Re-routing decision
- Short, high-immediacy result with broad significance in tight length →
geology.
- Highest-impact earth-science breakthrough for a general audience →
nature-geoscience.
- Carbon/nutrient/element cycling and budgets are the core →
global-biogeochemical-cycles.
- A documented dataset is the deliverable rather than the interpretation →
earth-system-science-data.
- Short, fast geophysical/geochemical communication →
geophysical-research-letters.
