Papers in Press

Welcome to the American Mineralogist Papers in Press (PIP) page. Recently all Papers in Press have been made open to all readers. These Papers in Press are unedited manuscripts 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.
