Papers in Press

Welcome to the American Mineralogist preprint page. Recently all preprints have been made open to all readers. These preprints are unedited manuscritps accepted for publication that will undergo copyediting, layout, and review of the proof before being published. Always consult the final, published document as a good practice. Remember to have your institution subscribe to American Mineralogist! Note that individual online subscriptions are via membership in MSA (and members get free online color in their paper) -- check out all the info via the pull-down links above including how to be an author and submit your paper.

All legal disclaimers that apply to the journal apply to these preprints. Please note that in almost all cases the authors hold the copyright. To identify those Open Access papers with a CC-BY or CC-BY-ND-NC license check the code at the end of the DOI.

The preprint is automatically deleted when the issue in which it appears is in print or posted online. While no corrections to these documents are possible, authors do have the right to contact to have the preprint removed if they would rather wait for publication.

Please cite these papers: Authors (Year) Title. American Mineralogist, in press. DOI.(DOI is live when article is live.)
