_{(A) Geologic map}

_{_____ If checked here, color each unit of uncolored map ozalid.}

_{Check for the following:}

_{_____ (1) Completeness of contacts}

_{_____ (2) Correctness of map-unit symbols (compare with DOMU)}

_{_____ (3) Consistency of line symbols (dashed where gradational or approximate, dotted where buried, or queried where uncertain). Structure symbols have thicker lines than contacts}

_{_____ (4) Agreement of triple junctions of contacts with stratigraphy shown in correlation chart}

_{_____ (5) Correct coloring of author-supplied copy}

_{_____ (6) Consistency of detail throughout map (unless image resolution changes dramatically); map is neither overly cluttered with symbols and unnecessary line work nor overgeneralized. (If more detail is required in an especially complex area, an inset map at larger scale may be included.)}

_{_____ (7) Geographic nomenclature is correctly shown and adequate}

_{_____ (8) Reasonable match of borders with borders of previously submitted maps at same scale (contacts, structure, relative ages). If author of later map cannot match, he/she should explain in DOMU.}

_{(B) Description of map units (DOMU)}

_{_____} (1) Unit names and symbols follow precedents, where applicable

_{_____ (2) Units are mappable based on described characteristics}

_{_____ (3) Important stratigraphic relations are noted}

_{_____ (4) Location noted if occurrence restricted}

_{_____ (5) Interpretation clearly separated from description; description contains no genetic terms; interpretation(s) consistent with unit description}

_{_____ (6) If type area is noted, it is the most definitive exposure}

_{_____ (7) Unit groupings have precedent or are clearly defined}

_{_____ (8) Format follows USGS guidelines (see VGM Handbook, Appendix D)}

_{(C) Correlation chart}

_{_____ (1) Relative ages of units agree with stratigraphic information in DOMU and crater-count data (if applicable)}

_{_____ (2) Format follows USGS guidelines (see VGM Handbook, Appendix D)}

_{(E) Map text}

_{_____} (1) Discussions are based mainly on map data; all appropriate references are cited (involved analyses should be presented in a journal article)

_{_____ (2) Good balance in presentation of interpretations (not overly biased or extensive)}

_{_____ (3) Previous work referenced; significant departures in mapping from same data are discussed}

_{_____ (4) Text agrees with other components of map; not overly redundant with DOMU}

_{_____ (5) Introductory material is useful. It generally includes brief discussions of the geologic and physiographic settings, data sources, and previous work}

_{_____ (6) Where geology is complex, special sections and (or) summary are provided}

_{_____ (7) Location of each feature refrred to is clear on map or a figure or is given verbally in text}

_{(F) Cross sections (if applicable)}

_{_____} (1) Topographic profile drawn accurately on stable material (such as mylar)

_{_____ (2) Consistent with stratigraphy and structure shown on map and correlation chart and described in text}

_{_____ (3) Line(s) of section and vertical exaggeration (if any) chosen to best show the structure}

_{In addition to completing this checklist, please annotate map materials with your comments. Lengthier comments should be typed separately. Please return all materials originally received (including route sheet signed by reviewer or initialed if reviewer requires a second look at the map) for the review to:}
