Interesting, I'll have to look for this.  My first reaction to the theory
would be that:
1) the hotter mantle would be more bouyant itself, so the plates would not
   need to cool as much to subduct.  I assume the authors address this.
   That is, I assume they checked and found that plate motion was so fast
   that it offset this effect.
2) Some large plates may not be attached to a down-going slab.  In this
   configuration, they would be free to age until they were cool enough
   to subduct.
3) Massive island arcs would form of relatively bouyant material until the arc
   basement was old enough to subduct.

I read somewhere that a flawless emerald was worth more than a flawless
anything else of the same weight.  This is because emeralds fracture very
readily and flawless ones of any reasonable size are next to impossible to
find.  Emeralds are my favorite, too, and I also wonder what causes the

Thomas Gold has an interesting article in Proc. NAS.  It was mentioned in
another thread recently.  He hypothesizes about microbial life beginning at
depth, and migrating *upwards* to the surface over geologic time.  It was a bit
short of data, but hopefully that will change in the future.

I think it is interesting to note how anaerobic bacteria can be found in (to my

estuarine sediments to animal guts.

I haven't heard about it for some time, either; I don't
know if it's still going on.

The idea was to drill two holes, close to one another.
Pump water down one, get high-pressure steam from the
other one.

The problems should be pretty obvious:

  - As usual for geothermal, you have to drill into
    very hot rocks - not easy on the drilling equipment.

  - You have to get the holes just the right distance apart.
    Not as hard now as it used to be; drilling technology
    has improved.

  - You have to find just the right fracture system to
    send the water through a large volume of hot rock
    without losing too much, or you have to make your
    own fractures.

I'd expect the "without losing too much" bit to be the
sticking point.

    The general points of this last post are well taken, however, we have
to be careful  about referring to plate tectonics in the early Earth. In
fact a recent article in GEOLOGY states pretty clearly that plate tectonics
could not have been operating in the first few billion years of the Earth.
The argument is basically this: the temperature of the mantle was higher so
its viscosity was lower, therefore the plates would have to move faster
(oceanic plates).  If things go fast enough, plates will reach the trench
before they have neutral or negative buoyancy and wierd things begin to
happen.  Those "wierd things" are certainly not understood at this point
and I would not put them in the same chapter as plate tectonics.  These
ideas were suggested by several people a few years back (Rob Hargraves is
one person) and I think this latest article by Davies(??) backs them up
quite well.

The earthquake that I posted information for turned out to
be the only one in the hypocenter data base for the state
of New Mexico in the years 1943 and 1944.  I'm sorry, but
that's all we've got here.  

I got an EMAIL from someone reading a cross-posting to 
another group reguarding this area.  He told me that this
is in the area of the "Carthage Site".  This is a magma
body that is moving toward the surface.  He wondered if
this quake might be related to this.  He suggested the
geology department at New Mexico Tech as a possible
source of info.  The New Mexico State Geological Survey
might also be a good source.  Don't forget to check the
newspapers in the area you are interested in.

Oh, the event location being accurate to within 0.5 
degrees is roughly the same as within 34 miles.

Hope this helps.  Please post some of your findings.
I'd be interested to see what you turn up.

This was clearly sarcasm referencing the earth shrinkers and expanders.
Two discreditted groups.  As best we can measure, the earth has had a constant
size (within error of measurements) for at least the last 15 million years.
The best evidence is closure of plate motion circuits in velocity space,
but there are other lines of evidence, such as direct gps measurements over
the past few years.

Volcanic eruptions will not change the earth's size (material is conserved),
the core temperature does not "fluctate", and the earth doesn't "settle"
(the pressure is high enough within 15 km of the surface that there is no
void space to settle).  The earth expanders believe in spreading, but
not subduction - they think that the gravitational constant G has gotten
smaller with time, so the earth is expanding.  The earth shrinkers believe
in mountain building through compressional tectonics, but not spreading,
they think the earth shrinks as it cools, explaining all the mountains.
The high pressures inside the earth dominate the effects on mineral volume,
not temperature.
