Introduction: Replace these instructions with the text of your abstract. Do NOT delete the section break above. The text will appear in two columns that are each ~3 inches wide. (Please make sure your paper size is set to U.S. letter, 8.5" × 11", before submitting your ab stract.) Page margins are set to be one inch on all sides, and your finished abstract should be no longer than two pages. If you are including tables or figures, they MUST be imported into this file.

Digital Formats: Any image file format that can be imported into this file will be acceptable for publication; to avoid technical problems, we suggest using TIFF (.tif) or GIF (.gif) files for photographs, and encapsulated PostScript (.eps) or Windows metafiles (.wmf) for line drawings. We ask that you use smaller-format files whenever possible (for example, don't use a 1-MB TIFF file if a 250-K GIF file provides acceptable resolution).

Heading Styles: The section heads in this template use the correct style (upper and lower case, bold, fol lowed by a colon). The format for second-level heads is show below:

Sample of a level-two head. Automatic paragraph indents are imbedded to appear every time you use a hard return. If you're using the spell checker and it doesn't seem to be working, check the "Language" option under the "Tools" to make sure that "No Proofing" isn't selected as the default. You should also check that the default font is Times New Roman and not New York (this conversion takes place on some Macintosh sys tems).

References: Use the brief numbered style common in many abstracts, e.g., [1], [2], etc. References should then appear in numerical order in the reference list, and should use the following abbreviated style:

[1] Author A. B. and Author C. D. (1997) JGR, 90, 1151–1154. [2] Author E. F. et al. (1997) Meteoritics & Planet. Sci., 32, A74. [3] Author G. H. (1996) LPS XXVII, 1344–1345. [4] Author I. J. (2002) LPS XXXIII, Abstract #1402.
