Meteorites 2017: A Curiosity of Proportions

Mon, 01 Jan 2018 23:20:16 PST

2017 was an interesting year from any perspective, meteorites included. But then again meteorites are always interesting so anything they touch becomes a curiosity as well. A few notable meteorite “things” caught my attention and here’s the short list. The first thing is that the top hits on Google for “meteorite” no longer begin with […](image)



Quitovac a New Mexican Meteorite

Mon, 01 Jan 2018 22:17:37 PST

I do not cut meteorites for anyone other than our business as a general rule. But, my friend Jason Phillips of Rocks From Heaven, contacted me about a newly recovered meteorite from Mexico that he wanted to get cut open to see its insides. So I said, “Sure send some pieces, and I will slice […](image)

Bob’s Bulletin – Vol. 4 No. 1  A newsletter for unclassified meteorites found in the USA. This month’s edition of the “Bulletin” focuses on just some of the recent US finds that I have had the privilege to document. *** Note: Not all of the meteorites depicted in this month’s article were found by me.

Cole Creek H5

Mon, 01 Jan 2018 18:49:44 PST

One of my first thin sections was Cole Creek H5. I’ve picked up a few more slides over time because it’s a fun meteorite to view in thin section. Barred olivine chondrules survived thermal metamorphism well. There is variety among the BO chondrules with a high proportion being compound. These photos are from four thin […](image)



Two Unusual Bow-tie Thailandites

Mon, 01 Jan 2018 17:38:31 PST

The upper specimen is a 120 gram giant that offers a great story on extensional necking and incipient parting. The odd little 12.4 gram piece, almost an order of magnitude smaller than the one above, remains a mystery to me. Both of these specimens are cylindrical in cross-section. It has long been accepted tektite dogma […](image)

Siena, Italy: The Meteorite That Started It All?

Wed, 01 Nov 2017 23:23:22 PDT

The famous and well respected Ursula B. Marvin penned an opinion tome in the September 1995 issue of Meteoritics suggesting that the Siena meteorite fall of 1794 is “History’s Most Consequential Meteorite Fall.” No matter how you slice it, it’s a tall order for a meteorite to be the Most Consequential. The abstract of Marvin’s […](image)



Another book on Meteor Crater

Wed, 01 Nov 2017 22:33:30 PDT

I finished a two-year long project a few days ago. It is a new book and it is about Meteor Crater again. Yes I know I am in a rut. But I am not going to talk much about the book itself. What I want to tell you this month is the story of the […](image)



Bob Hoover – 1938-2017

Wed, 01 Nov 2017 20:12:45 PDT

Commemorating the life of my friend and of our fellow meteorite-hunting colleague.The recent passing of Robert Hoover has prompted me to postpone this month’s article, and instead to make notice of this sad news. Robert Dan Hoover, Born in Corona, CA on January 25, 1938 passed peacefully while in hospice care near his home in […](image)



Mukundpura CM2

Wed, 01 Nov 2017 18:17:19 PDT

CM2 meteorites are regolith breccias. They’ve been through cycles of crushing and lithification at an asteroid surface. They are dark with opaque matrix and varying amounts of chondrules, olivine aggregates, CAI and mineral grains. This is a sample of a CM2 fall that is reported to have distinct lithologies. Our samples, whose early field name […](image)



Ferricrete adhesions on Thailandites

Wed, 01 Nov 2017 17:19:26 PDT

It is one of the interesting factoids of tektite lore: Never, not even once, has a splashform tektite been reported that shows an embedded object or clear imprint from the ground surface on which the tektites fell. However, that noteworthy constant only serves to sharpen the search for the first one. Most tektite aficionados have […](image)

Good Bye Cassini. Hello Saturn Meteorites

Fri, 01 Sep 2017 23:03:40 PDT

Back in 2004 I wrote a column for The Meteorite Times about my journey with Saturn and Cassini. By the time you read this the Cassini spacecraft will have said goodbye to us on earth and plunged into Saturn’s icy atmosphere, all 22 feet and 12,500 pounds of her (well, actually only 4,685 pounds since […](image)



Impact Breccias Another Visit

Fri, 01 Sep 2017 22:54:49 PDT

Years ago I collected many more things. As a child, I collected stamps and coins. As an adult, I have collected tektites, antique balance scales, civil war artifacts, fossils, meteorites and more. I have reduced my collecting in the last couple decades to very slowly adding some additional meteorites only. I have stopped buying anymore […](image)
