Meteorite**Gold Basin, Mohave Co. Az USA**111.00 grams Individual W/fusion crust

Description

Hello up for auction is a extremely ancient meteorite named Gold Basin found in Mohave Co. Az USA. This beautiful individual weighs 111.00 grams, has beautiful fusion crust, one of the oldest meteorites in the USA and best on the Market!! The Gold Basin meteorite was discovered by Prof. Jim Kriegh (Emeritus, University of Arizona) while prospecting for gold with a metal detector on 1995 November 24 in the eastern portion of the Mojave Desert in northwestern Arizona, USA. This meteorite comes with 2 COA cards, KD meteorites and mine. Thanks for your interest and take care.
Note: This is a historic USA find and much more rare and valuable than Northwest African meteorites

Gold Basin
Mohave County, Arizona, USA
Initial find 1995 November 24
Ordinary chondrite (L4)
A meteorite was found in an area of arroyos draining the White Hills by Professor Jim Kriegh (UAz, emeritus) while prospecting for gold with a metal detector.  As of 1997 November, 1484 stones have been recovered, with a total mass of 61.0 kg, from an area of ~130 km2.  The largest individual stone has a mass of 1.52 kg.  Classification and mineralogy (D. Kring, UAz):  olivine, Fa24±1; pyroxene Fs20Wo1; kamacite contains 0.72 ± 0.09 wt% Co; weathering grade W2–3.  Specimens:  UAz, 0.8 kg; SI, 8.4 kg; bulk of the mass with Jim Kriegh and his fellow collectors.
The Gold Basin meteorite was discovered by Prof. Jim
Kriegh (Emeritus, University of Arizona) while prospecting for
gold with a metal detector on 1995 November 24 in the eastern
portion of the Mojave Desert in northwestern Arizona, USA.
The initial find consisted of two fragments (-13 g total mass)
whose morphologies indicated they were part of a larger object.
Subsequent field studies by Kriegh, J. Blennert, and I. Monrad,
and one of us (D. A. K.) were designed to map the extent of the
strewn field and recover as many samples as possible. Initially,
approximately 2000 specimens were recovered over a 160 km2
area (Kring et al., 1998). More recent fieldwork by Kriegh,
Blennert, and Monrad has increased the number of samples to
-4450 over an area of -225 km2 as of July 2000 (Fig. 1).
Reports from private collectors suggest -1500 to 2000
additional specimens may have been found. We do not believe
the full extent of the strewn field has been mapped, so the current
size is a minimum. Indeed, mountains surrounding the basins
where most of the samples have been found may make it
impossible to ever fully map the original extent of the strewn
field.
Most of the fragments were found using metal detecting
techniques. Visual identification is difficult, because the
samples are often the same size and color as other desert
pavement constituents (Fig. 2) or lie buried beneath the
surface (up to 10 inches deep). Specimens were found in a
fine-grained loose soil and were partially to wholly encased
in caliche.
Rare stones are completely surrounded by fusion
crust, but most samples have partial fusion crusts and
fractured faces. The fusion crust is variably preserved.
Sometimes it is still vividly black, but in other cases it is
patchy andlor has turned a rusty red color. Rusty halos
around metal grains exposed in the fractured surfaces are
visible in hand specimens. Some samples recovered from
the desert pavement are coated with desert varnish. Samples
were also found on mountain slopes and in drainage systems.
As discussed below, this range of environments in the strewn
field affected the range of weathering and oxidation seen in
the recovered samples.
