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. :tongue3:
 

The one right above E.
I heard they have nickel in them. :tongue3:

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

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

So Terry, I know the suspense isn't nearly over yet, but just when DO you plan on giving us the answer?? :laughing7:
 

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!
 

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! :tongue3:
 

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

OK folks, Last call for guesses! I'll give the answer tomorrow, Sunday, 7-10-16. :occasion14:
 

Hmm...my clock is showing 12:25am, 10 JULY 2016, which is now Sunday! :laughing7:
 

OK, let's say 6pm EST? :occasion14:
 

I say all of them...
 

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! :occasion14:
 

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.
 

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

You're enjoying this too much!! :laughing7:
