epsl-topic-selection

Use when deciding whether a result fits Earth and Planetary Science Letters (EPSL) and how to frame it. EPSL takes concise, high-significance Letters on physical, chemical and mechanical processes of the Earth and planets, and desk-declines regional case studies without process-level insight, so this skill pressure-tests the frontier claim before you invest. It frames the contribution; it does not run analyses.

# Topic Selection & Fit (epsl-topic-selection)

EPSL's identity is in its name: **Letters**. The journal wants a short paper whose single result moves
a *frontier* — how planets differentiate, how mantles convect, how faults load, how climate signals
enter the rock record — not a competent study whose relevance stops at one basin, one orogen, or one
sample suite. Deciding fit early saves months, because the frontier-vs-incremental judgment is made at
the editor's desk.

## When to trigger

- Choosing between EPSL and a specialist or regional venue
- Sharpening a dataset into a process-level question
- Worried the paper reads as "another case study from region X"
- Tempted to split one project into companion papers (EPSL discourages this)
