Can You Identify The Meteorite in this Photo?

[Terry Soloman]

Can you correctly identify the meteorite in this photo. It is an L4 Ordinary Chondrite - [FONT=&quot]The recommended classification [/FONT]L4[FONT=&quot] means: [/FONT][FONT=&quot]"An [/FONT][FONT=&quot]ordinary chondrite[/FONT][FONT=&quot] from the [/FONT][FONT=&quot]L group[/FONT][FONT=&quot] that is petrologic [/FONT][FONT=&quot]type 4[/FONT][FONT=&quot]." [/FONT][FONT=&quot]The highlighted words are defined as follows:[/FONT][FONT=&quot]
ordinary chondrite: A major class of chondrites, distinguished by sub-solar Mg/Si and refractory/Si ratios, oxygen isotope compositions that plot above the terrestrial fractionation line, and a large volume percentage of chondrules, with only 10-15 vol% fine-grained matrix.[/FONT]
[FONT=&quot]L group: The low-iron (L) chemical group of ordinary chondrites, distinguished by their relatively low siderophile element content, moderate sized chondrules (~0.7 mm), and oxygen isotope compositions that intermediate between H and LL group ordinary chondrites.[/FONT]
[FONT=&quot]type 4: Designates chondrites that are characterized by abundant chondrules, and have been metamorphosed under conditions sufficient to homogenize olivine compositions and recrystallize fine-grained matrix. Some of the low-Ca pyroxene grains may be monoclinic and exhibit polysynthetic twinning. Primary igneous chondrule glass is absent. Meteoritical Bulletin: Recommended classifications

My eye is attracted to "B", but I want to say "D". Therefore, it's most likely "G", which is the farthest from my guesses.

 

[Deft Tones]

The one right above E.
I heard they have nickel in them.

My real guess is C. But I also am partial to B.

 

[Tuberale]

I'd guess E, but D would be a close 2nd choice.

 

[TommyB]

My guess is G. Way too much info to 'help' us decide. Not even in english

 

[kcm]

So Terry, I know the suspense isn't nearly over yet, but just when DO you plan on giving us the answer??

 

[Deft Tones]

After re-reading the OP, my opinion is that the meteorite can only be identified positively by analysis of a sample. Microscope, spectroscope, whatever.

I admit I'm ignorant of topic, but I'm interested in the answer and willing to learn!

 

[kcm]

Well, he says it's Chondrite, which means no metal.

You're not alone DT. My "entire" knowledge base concerning meteorites comes from watching Meteorite Men!

 

[TerryC]

My choice would be H but it's not an option! TTC (Hey Terry!)

 

[austin]

I think they ALL are...

 

[Terry Soloman]

OK folks, Last call for guesses! I'll give the answer tomorrow, Sunday, 7-10-16.

 

[kcm]

Hmm...my clock is showing 12:25am, 10 JULY 2016, which is now Sunday!

 

[Terry Soloman]

OK, let's say 6pm EST?

 

[masterjedi]

I say all of them...

 

[Terry Soloman]

What do you think? Are any of these space rocks? All of them? Just one of them? I'll tell you at 6pm EST today, so take a guess.

A Prize? Yes! The joy of being right, or the new knowledge you gain by being wrong. Cheers!

It's B fusion crust.

 

[Leeway1]

I pick D. That and F are the best looking ones to skip across the lake if they aren't real ones. Then it will have taken flight at least a few times.

 

[Wyoming Valley Relics]

It's B fusion crust.

thats what i thought too, B.

 

[BigWaveDave]

You want identification?
Ok, A, B, and G are obviously females, with their wide hips and all...Irene, Pearl, and Shirley...
