Although there are some interesting questions about Columbia River Basalts and glacial deposits that I would like to answer, I am unfortunately busy getting ready to go to Louisiana for the annual Gulf Coast Association of Geological Societies meeting starting Wednesday evening and lasting through Friday with a all day field trip Saturday. This is how geologists stay in touch with what other geologists are doing by listening to talks; looking at posters; talking with other geologists;, and actually looking at the geology close up and dirty on field trips. In fact, I will be meeting, on the side, in person for the first time with other geologists, who either are or plan to be active in preparing written reviews of Young Earth creationist arguments and ideas for the lay public over a beer or two and, possibly dinner.
Until, I have time to get back to flood basalts and continental glaciers, I will leave people on this list with a couple of references to wind-blown diatoms that I found on the Internet. They are:
"BIBLIOGRAPHY ON WIND-BLOWN DIATOMS, DIATOM
DISPERSAL AND AEOLIAN PARTICLES collected by
Margaret A. Harper" at:
Indiana University Bloomington
and
Evidence for Dust Bowl dust in Greenland
Geotimes - June 2003 - Geophenomena
"they dated the dust and found that it arrived in
Greenland between 1933 and early 1934; the
clay minerals of the dust correlate with either
an American or African origin; and the diatoms
they found - the silica shells of aquatic algae
that can travel with the wind - were all
common North American species,..."
Yours,

old news
From the first link;
quote:
particles <16 um
From the second link;
quote:
"They had to use SEM because of the small size of their samples,
The diatoms in quesition are very small and are in the size range expected to be transported by the wind, this is old news, as I posted in an old post: "empty valves of freshwater diatoms are common components in aerosol samples and can be transported around the globe, but these particles are typically <25 um diameter or 60 um long (Pye, 1987). These data from different environments indicate that eolian hypothesis does not represent a suitable mechanism to transport 100 to 240 um size particles" Which is a quote from an aritcle on wind transport of diatoms.

--I suggest a thorough review of Baumgardner's model of Runaway Subduction. Maybe they can produce something new and detailed unlike everything extant on the web.

What runaway subduction produces is a sterilzed planet. I don't think you can fix that over dinner or any other way for that matter.

Randy references one of the threads where the Runaway Subduction topic is more appropriate. You could resume discussion of this topic in one of those threads, or you could open a new thread.

--Excuse me for being frank, but you can get into a hell of a lot more detail than that, as well as much more comprehensive...
--Regarding the issues in that thread, when I plan on discussing them it will occur in that thread (or I will open a new thread in response to the more recent issues in that thread).
