Small bodies examined to date exist in varied dynamical environments and have very different mean radii, shapes and apparent ages. To facilitate geological interpretations of individual bodies and comparisons between them, I propose a geological framework which can be applied to asteroids and small satellites. No absolute chronology is involved, but relative ages are implied. Five orders of impact event are described: parent body fragmentation, facet formation, impacts which shake the whole body, small craters and regolith 'gardening' microimpacts. Phobos, Deimos and Gaspra are described in these terms. For Phobos, Order 2 (facet-forming) impacts older than Stickney are found, any or all of which might have initiated groove formation, and Stickney-related features may be extensive enough to form a global time marker for geologic mapping.
