Hi all,

Just wanted to give everyone a quick heads up on our newly classified pallasite!

Sterley 34.21°N, 101.39°W

Texas, USA

Found: 1950

Classification: Pallasite (Main group)

History: A single mass weighing 1724.8 grams, and displaying regmaglypts and some remnant fusion crust, was found ~1950 by a farmer while plowing. Several months later, the finder took the specimen to Texas Tech University where it was classified by a mineralogist Mr. Dennis as a " stony iron siderolite - variety pallasite". Decades later, after watching a television show on meteorites, the son of the finder took the specimen to Dr. Laurence Garvie at the Center for Meteorite Studies, ASU for further study. The pallasite was later purchased by Ruben Garcia and Geoff Notkin.

We'll be ready to post photos and start selling slices on Jan 1, 2013 - Until then check out the photo of this fantastic specimen before it was cut!

Did you happen to notice the Ram's Head heading down the mountain on the left side of that picture?

Whats the difference between what it was originally classified as and what it is reclassified as of now? Real nice looking stone by the way. Wish I could afford something like that.


Hi Steve,

When the stone was first found it was NOT classified but only identified by TEXAS TECH as a stony-iron or pallasite. This is the first time it's been classified - and by the best in all of meteoritics -John Wasson (UCLA) and Laurence Garvie (ASU)

Hey Jim,

Yes, you're right...

Most people don't realize that there are far more Lunar and Martian classifications than there are pallasite. Think about this, there are only 38 known pallasites including Sterley as opposed to 164 Lunars and 110 Martian meteorites!

Below are the only USA pallasites with less TKW than Sterley - so ya, it's rare!
