Appendix E: Submission Checklist for Planetary Geologic Maps

Map Title:____________________________________________________________________________


Submission date:______________________________________________________________________

Date of completion of coordinator review:_________________________________________________

(A) Geologic Map (and Cross Sections)

_____ (1) All outcrops are labeled with unit symbols; symbols and colors are same as those elsewhere in material.

_____ (2) Contact lines are complete and neat. Check for line breaks and irregularities.

_____ (3) Dashed, buried, and queried lines and scratch contacts, if used, are clearly shown. (For economy's sake avoid dashing long stretches; instead explain in text the indefinite nature of contact.)

_____ (4) Superposition relations are clear and consistent with text.

_____ (5) Line symbols match those of earlier adjoining maps where possible; if not, discrepancies are explained in text.

_____ (6) Structural symbols are clearly identified and have obviously thicker line weight than contacts.

_____ (7) Cross sections are consistent with map in every detail. (See Suggestions to Authors.)

(B) Description of Map Units (DOMU) and Explanation

_____ (1) Format of DOMU follows conventions shown in Appendix D, Venus Geologic Mappers' Handbook (give close attention to this!)

_____ (2) Order of DOMU follows order of correlation chart. Map units described by grouping in chart (from left to right) and then from youngest to oldest (see DOMU and chart samples, Appendix D, VGM Handbook).

_____ (3) Each map unit is described in following order: (1) Definitive characteristics, (2) secondary characteristics, (3) stratigraphic information, (4) location (if not obvious on map), (5) type area (optional; for new units only), and (6) interpretation (separate from description.

_____ (4) All unit and feature symbols on map are shown and explained (and vice versa); symbols follow precedents where applicable.

(C) Correlation Chart

_____ (1) A box for each map unit is included and properly colored.

_____ (2) All unit groups and subgroups are shown, as well as their names. (See example of correlation chart in Appendix D, VGM Handbook)

_____ (3) All stratigraphic positions are shown by relative vertical ranges of unit boxes and match relations and descriptions shown on map and in text and DOMU. Major stratigraphic divisions (e.g., Amazonian, Hesperian, and Noachian) and crater-density correlations are shown where applicable.

(D) Map Text

_____ (1) Text is in logical order (e.g., Introduction, Stratigraphy, Structure (and(or) other special sections), and summary).

_____ (2) Under Introduction, note briefly any previous work in area, its scale, and type of images on which it was based; also, note resolution(s) of images used in present mapping.

_____ (3) Under Stratigraphy, units and events are described from oldest to youngest.

_____ (4) Geographic names mentioned are shown on map base or in a figure, or their map coordinates are given in text. (In preparation of published map, drafters will routinely transfer to it all nomenclature from base.)

_____ (5) Unit names agree exactly with terms used in DOMU (do not paraphrase).

_____ (6) All references are listed in "References cited."

(E) References Cited

_____ (1) All references cited appear elsewhere in the copy material.

_____ (2) USGS reference format style is followed (See USGS Suggestions to Authors or reference list on p. 30-32 in VGM Handbook.)

(F) Additional Figures, Tables and Color Plates (if any)

_____ (1) Figures and tables in text are numbered sequentially.

_____ (2) Each figure and table should stand alone. (Caption contains all information necessary for comprehension, and text does not repeat this information.)

_____ (3) For images, north and illumination directions and image number(s) are noted; scale bar is provided. Use annotations showing discussed features.

(G) Enclosed Materials

(Keep brownline and originals of images until they are requested)

_____ (1) One colored and three uncolored copies of map, correlation chart, and any color plates or cross sections.

_____ (2) Three copies of map text, DOMU, explanation, figures and captions, and tables.

_____ (3) Include any special instructions in cover letter.

_____ (4) Completed check list.
