Hello everybody. This is just to clear up some confusion that has
arisen regarding meteorites recently found in the Franconia wash region
east of Kingman, AZ. As a number of you already are aware, there have
been a number of new Chondrites found in the region loosely referred to
as "Franconia wash". These appear to range in composition from LL5 to
H5. We have at least two and perhaps three different Chondrites from
this region (none of which have been classified as of yet). Bob Verish
has one of these meteorites which has been classified as an (H5) and
given the name 'Franconia'. In a recent posting Bob stated that only
his stone can "be properly called Franconia". We are assuming that he
meant that only his stone can properly be called the Franconia 'type
specimen'. As with any meteorite fall, all individual members of that
fall are both individually and collectively referrred to by the name
given to the type specimen, in this case 'Franconia'. We have posted on
our website (http://www.arizonaskiesmeteorites.com) several slices from
an individual found in the Franconia wash strewn field by Jack Schrader,
which we stated was unclassified and which appears to be extremely
similar to the Franconia slices posted by Bob Verish
(http://www.geocities.com/bolidechaser/mrf/franh5-g.jpg). Please
compare these slices and draw you own conclusions. It is of course
possible, though not very likely, that two very similar meteorites fell
in the same strewn field. If indeed these are from the same fall, then
they should of course all be referred to as 'Franconia'. If they are
from a different fall, then they represent a New, and as yet
unclassified, Arizona chondrite. In either case, this is an exciting
find, and once the classification of these chondrites is verified we
will update everyone. This might be a good opportunity to get a nice
slice from a new Arizona Chondrite while the prices are still
reasonable. If anyone has any questions please feel free to email us.


Thanks
