Attached is a preliminary version of a digital database (in Access 2000 format) of large mafic magmatic provinces through time. An enhanced version of this database is being prepared for release as an Open File.  Apart from a few minor corrections, it represents Table 1 in R.E. Ernst and K.L. Buchan (2001), "Large mafic magmatic events through time and links to mantle plume-heads" (chapter 19 in "Mantle Plumes: Their Identification Through Time", Geological Society of America Special Paper 352, edited by R.E. Ernst and K.L. Buchan). 

Additions and corrections to the database are welcomed and can be sent to Dr. Richard Ernst (rernst@nrcan.gc.ca; 613-995-4386 office; 613-995-7997 FAX; rm. 586, 601 Booth St., Ottawa, ON K1A 0E8).
