Abstracts, Manuscripts, and News Releases


Tollo and Gottfried, 1989  -- An extended abstract for a symposium of the International Association of Volcanology and Chemistry of the Earth's Interior, held June 25-July 1, 1989 in Santa Fe, New Mexico. I like their thesis very much; in fact, this little paper, with its clear writing and logical conclusion, is much better than some long papers we all know, where much effort is expended to promote a bad model.  Thanks to Dick Tollo for sending it to me.

Olsen et al., 1996 -- Abstract & Figures as posted in Roy Schlische's Extensional Tectonics web site, for their paper called: 580 ky duration of the Early Jurassic flood basalt event in eastern North America estimated using Milankovitch cyclostratigraphy, by Paul E. Olsen, Roy W. Schlische, and Michael S. Fedosh, in The Continental Jurassic, edited by M. Morales: Museum of Northern Arizona Bulletin 60, p. 11-22.

Broad-Terrane Basalts Paper  -- The manuscript version of my Geology paper (McHone, 1996), which proposed that lavas also flowed outside of Mesozoic basins from the same feeder dikes that fed basin basalts (well, duh!).  Seemed like a radical idea at the time, and I still get some flak from stratigraphers.  The description was confined to the initial basalts and feeder dike system of northeastern North America, which is a big system but tiny compared to all of CAMP.  I was too timid at the time to go farther, and so Andrea Marzoli and colleagues beat me to it in their 1999 Science paper.

CAMP News Release -- from the University of California - Berkeley, related to the publication in Science by Marzoli et al. in April, 1999.  Paul Renne was his advisor and co-author.  There were many newspaper reports linked through the A.P services to this event, but some of the reports were rather garbled by their editors.

Non-Plume Paper  -- A brief manuscript published by Tectonophysics (2000, v. 316, p. 287-296), which was submitted at the invitation of Alan Smith (see his new paper in Earth Science Reviews).  There are also a few other "non-mantle-plume" papers that made it to publication, listed in the bibliography.  There is little evidence to favor a mantle plume origin for CAMP basalts, despite the popularity of that model (also see AGU abstracts linked on the index page).  Things are changing fast, but this paper is a fairly recent summary.

CAMP Volcanism Abstract -- Constructed for the Penrose 2000 Volcanic Rifted Margins conference, to be held near London in March, but I ended up submitting the next one instead.  Paul Ragland and I are working on a manuscript that will expound on the geochemical groups of CAMP.

CAMP Non-Plume Abstract -- The one actually submitted to the Penrose Conference in December 1999.  Based on my 2000 Tectonophysics paper.

Volatile Estimates Abstract -- Similar to my abstract for the 2000 Northeastern Section meeting of the Geological Society of America.  A manuscript based on this talk is underway, intended for an AGU Memoir based on the 1999 AGU spring meeting symposium.

Mapping CAMP Abstract -- Similar to my recent submission to the 2001 Northeastern Section meeting of the Geological Society of America.  This will be a poster session, so please come by to chit-chat about my maps and plots if you attend the meeting.

Extent and Environmental Significance Paper -- a manuscript version by McHone and John Puffer of our chapter in an upcoming book edited by P. M. LeTourneau and P. E. Olsen, 2001: Advances in Triassic-Jurassic Geoscience, Columbia University Press, NY.  It was mostly written in 1997 following a 1996 conference, so portions are a bit dated, but the basic thesis is still current.  There are three other important papers in the CAMP section of this book, as well as an introduction by Olsen and McHone.

Mesozoic Geology of Grand Manan -- a field guide manuscript in PDF format for the 2001 NEIGC meeting, to be held Sept. 21-23 (my trip is Saturday the 22nd) out of St. Andrews, New Brunswick.  Grand Manan is a large island in the southwestern corner of the Fundy basin, and it exposes great cliffs of North Mountain basalt plus a large dike -- see photos on the CAMP photo page.  Lucky for me, few people are familiar with Grand Manan geology, so maybe I will get away with these very tentative and preliminary discussions and descriptions.  Sandra Barr of Acadia University has provided much new data for this project.

"The Triassic Basalts and Continental Rifting" -- an on-line chapter from the Natural History of Nova Scotia, concerning the North Mountain basalts of the Fundy basin, published by the Nova Scotia Museum of Natural History.  Of course, the basalts are actually Jurassic, not Triassic.
