An Interplanetary Ambassador: The Gibeon Meteorite

An Interplanetary Ambassador: The Gibeon Meteorite

Sometime late last century I purchased a chunk of Gibeon iron from Blaine Reed. It was a very well formed complete individual that contained many of the features I needed. Yes, needed. For this particular iron was going to earn its keep as a tool for teaching about the solar system. Since that time, literally […]

Tieschitz H/L3.6

Tieschitz H/L3.6

Tieschitz is interesting in thin section. In our sample, large and small chondrules are set apart by opaque matrix. Radial pyroxene and cryptocrystalline chondrules display aqueous alteration. One large chondrule contains several relict grains. We see chondrules that appear to be radial olivine darkened with fine included particles, probably amphiboles or other alteration products, and […]

Dr. Arthur Ehlmann

Dr. Arthur Ehlmann

Personally, I have known Dr. Ehlmann a long time. How long exactly? Since I received a question through EBay… It must have been early in 2001. I had posted a small fragment of NWA 753 Rumurutite and this person was asking if I had a much larger piece available,—perfect spelling, perfect grammar and punctuation, unusual […]

NWA 10731 a Fascinating Stone

NWA 10731 a Fascinating Stone

It is always exciting for me when I get the word back that a meteorite has finished being classified and is off to be approved. That happened several weeks ago for Paul and me. Three meteorites I had found while cutting a mixed box of stones looked unusual enough to warrant being sent off and […]

Part  2 – Tektite or Impactite or Obsidian Pseudo-tektite?

Part 2 – Tektite or Impactite or Obsidian Pseudo-tektite?

Preliminary results from quick tests with a handheld XRF show that you can tell the difference.   Recently I was able to get access to a hand-held XRF analyzer (a Thermo Niton XL2 GOLDD unit). After much delay due to hardware problems and scheduled maintenance, I was finally able to test the various specimens of […]

Splatform Tektite Basal surface textures

Splatform Tektite Basal surface textures

Splashform tektites largely assumed their geometric form during aerodynamic flight, giving rise to a wide variety of dumbbells, teardrops, patties, spheroids, and similar forms. Amongst the splashforms, there is a subclass which I term “splatforms” which show deformation of primary shapes suggestive of having “splatted” against some hard surface while yet very plastic. In the […]

Zhamanshin Exploration

Zhamanshin Exploration

by Roman Davidov (revisited from the June 2003 issue of Meteorite Times) Zhamanshin. This word translated from Kazakh language like “bad soil” or “land without anything growing on it”. Firstly, peculiarity of this place noticed in 1936 by V.Vahrameev and later in 1941 by A.Yanshin. This two scientists noticed the presence of Paleozoic rocks among […]
