[meteorite-list] E-chondrites
List: I have a question regarding E-chondrites. I was told that Enstatite Chondrites have a more gray (dark) matrix than an ordinary chondrite. They also contain more metal (as a rule) than a typical H-chondrite. Now I always thought it was impossible to recognize an E-chondrite by eye. However, is it possible to recognize an E-chondrite by eye (10x lens) with the color of the matrix and amount of metal?

Im alvays a little surprized how Moroccans can recognize that chondrite is E-type. From my 12 years collecting/dealing practice, I can recognize most of types by eye (so Moroccans also can do this ofcourse), except E-chondrites. For me they are typical OC impossible to recognize without lab tests, especially when specimen is complete. Thats why I never bought possible e-type chondrite from Morocco.

Re: [meteorite-list] E-chondrites
I noticed that with the heavily weathered examples they develop a yellow sulfur looking powder in spots. The OC's tend to have a little more orange rust color. I'm not saying this is an accurate indicator but rather, I am wondering if others have noticed this as well. Tom In a message dated 12/21/2009 10:42:38 A.M.

Re: [meteorite-list] E-chondrites
E chondrites have virtually no matrix. Most of the material between chondrules and chondrule fragments is metal and sulfides. jeff On 2009-12-21 12:02 PM, Greg Stanley wrote: List: I have a question regarding E-chondrites.
