Bob's Findings - A Gallery of Images of a Meteorite from the California Mojave Desert

This stony meteorite still needs to be classified. At first UCLA said they would, then they changed their mind.

Photo Gallery of the FRAGMENTS & TYPE-SPECIMEN for the meteorite find appearing in this edition of "Bob's Bulletin" Newsletter:

USA180513:

UU180122-0
Above is the image of all of the fragments of “USA180513” currently recovered. The pieces on the right still retain some of the devitrified, relict fusion-crust on their weathered, caliche-covered exteriors. The smaller fragments on the left are from the interior of this chondritic stone and have no caliche.

UU180513
Above is the image of all of the larger fragments of “USA180513”, each of them retaining a patch of the devitrified, relict fusion-crust on the weathered, caliche-covered exterior.

UU180513
Above is the image of all of the smaller fragments of “USA180513”, coming from the interior of this chondritic stone and have no caliche, which means they are less weathered. An assortment of these fragments will comprise the eventual type-specimen. What remains will be retained for collectors.

UU180513
Above is an image of three of the more than 120 fragments from the “USA180513 - cluster”, two of which have had their cut surface polished (which shows a weathered, yet potentially unequilibrated interior).

UU180513
Above image is of a “USA180513” fragment after having a sample cut for a thin-section of the type-specimen, showing the potentially unequilibrated-chondrite interior. This specimen was made "wet" with denatured alcohol.

UU180513
This is a close-up image of the cut & polished surface for the above fragment (previous image). This is typical for all the other >120 fragments from the “UU180513 - cluster” (showing a potentially unequilibrated interior).

UU180513
Above is a close-up image of the other fragment which was cut & polished -- one of the more than 120 fragments from the “UU180513 - cluster” (which shows a weathered, yet potentially unequilibrated interior). This specimen was made "wet" with denatured alcohol.

The above "Gallery" is just one example of a way in which to record actual, but unclassified, meteorites.

In the meanwhile, I will do my part and continue to gather data, regarding "rare but unclassified meteorites".
