The revisions to this webpage were the result of the findings from a study that was presented at the Lunar and Planetary Science XXXVI (2005) Meeting (LPSC 2005). This poster presentation was titled:
"ATMOSPHERIC FRAGMENTATION OF THE GOLD BASIN METEOROID AS CONSTRAINED FROM COSMOGENIC NUCLIDES"
by Kees Welten, D. J. Hillegonds, A. J. T. Jull and David A. Kring
and this is the link to that abstract:
Among other things, this abstract concluded that:
Now that Gold Basin (L4) has been "reclassified" as (L4-6), any "Hualapai Wash NUMBERED" stone that has been classified as "L6" can now be renamed "Gold Basin (L6)". This means that ONLY those Gold Basin Area stonys that have been CLASSIFIED as an L6 can be called "Gold Basin (L6)"! Even giving a specimen the more general name "Gold Basin (L4-6)" implies that it has been classified (as an L-chondrite). To be fair, and accurate, all "untested" stones should just be referred to as "Gold Basin AREA" or "Gold Basin (UNCLASSIFIED)" meteorites.
Classified originally as an "L4" chondrite in 1995, these chondritic stones that come from the Gold Basin strewn field are well represented in collections all over the world.recognized. Since then, AT LEAST 30 OTHER meteorite stones, that have been found NEAR OR WITHIN this strewn field, have been CLASSIFIED.
As many as 10 of these are considered as "unpaired", or, if you will, as being "overlapping" with the Gold Basin strewn field!
GOLD BASIN IS A PART OF A LARGER DRAINAGE SYSTEM, KNOWN AS HUALAPAI WASH. THERE HAVE BEEN A VARIETY OF NEW METEORITES FOUND IN THIS AREA OF NORTHWESTERN ARIZONA. THERE ARE A NUMBER OF OTHER METEORITES FOUND IN THIS GENERAL AREA, WHOSE FIND LOCATIONS MAY OR MAY NOT BE WITHIN THE GOLD BASIN STREWN FIELD, AND THEY HAVE BEEN FORMALLY NAMED AFTER NEARBY FEATURES, SUCH AS MINES OR MOUNTAINS. THESE ARE LISTED BELOW, AS WELL.
The Following Table Lists All of the "Gold Basin Area Meteorites"
