[meteorite-list] The scientific importance of subtype 3.00 meteorites and oxygen isotope analysis
Well, with the LPSC going on starting this week, I sure hope we get some participation from our scientific contributors to these questions. Someone asked me to explain the scientific importance of meteoritic material with a 3.00 subtype. Reading through The onset of metamorphism in ordinary and carbonaceous chondrites by Grossman and Brearley 2005, I realized that a key tool used in the analysis of NWA 7731 and NWA 8276 was not present in the literature. So, I'll start with this first part of questions: In my discussions with Dr. Agee, he mentioned that the heterogeneity of the oxygen isotope results is important because it indicates that the material has not been metamorphosed by heat or shock. Any heating would have caused the oxygen to begin to equilibriate. So, is the oxygen isotope analysis something that should be added to the list of factors used in evaluating low sub-types? Or is it a proxy for more complex tests? I am hoping that Karen Ziegler can also add some insights. The second set of questions is perhaps more complex. What is the scientific importance of the 3.00 subtype? I can get this one kicked off, but would appreciate a more nuanced answer than what I can provide. The subtype 3.00 represents the earliest glimpse of the properties of proto-planetary material in our solar system. A subtype of 3.00 means that the material has survived unchanged by heat (radioactive decay, pressure, impact/shock, etc.) or aqueous alteration since its formation. An implication of the unequilibrated nature of this material is that the parent body had to be quite small for it not to differentiate in any way. Though both scientifically important, what different types of insights do we gain from CAIs versus subtype 3.00 material? The answer is I am sure that they complement each other, but in what way. Which is oldest? The rarity of this type of material cannot be underestimated since between the only 3 known (Semarkona, NWA 7731 and NWA 8276), there is only 1,561g available for research and/or collectors. Of that total weight, Semarkona's 691g is almost unattainable. So, once again NWA delivers the goods!

Re: [meteorite-list] The scientific importance of subtype 3.00 meteorites and oxygen isotope analysis
Mendy and list, My comments: Oxygen: I would say that O isotope heterogeneity as described here is not a good measure of metamorphism. Oxygen heterogeneity in these objecbulk samplests will be a function of sample size, as fine matrix grains equilibrate much more quickly than coarse ones. If you analyze small aliquants of sample, most UOCs will be heterogeneous. If, on the other hand, we were talking about the O isotope heterogeneity of individual olivine grains, akin to how we measure FeO in olivine, you might be able to devise a metamorphic parameter. But so far, I'm not aware of anybody devising a way to use O isotopes to measure metamorphic grade. The meaning of type 3.00: you said, A subtype of 3.00 means that the material has survived unchanged by heat (radioactive decay, pressure, impact/shock, etc.) or aqueous alteration since its formation. This is incorrect. It means the material is unaffected by thermal metamorphism. Semarkona is shock stage S2, so it has been seen elevated pressures due to impacts on the parent body. It also shows abundant evidence for light aqueous alteration. You can think of all these things as independent processes. Semarkona saw little heat, but got a little shocked and a little bit wet. Many CM chondrites saw little heat, but a lot of water. I would call these CMs type 3.00 as well, but traditional usage has coined another term for really wet chondrites, namely type 2. Oh well. Metamorphically, they are type 3.00. Some chondrites saw little shock and a lot of thermal metamorphism. Anyway, all type 3.00 means is that the object saw little prolonged secondary heating. The parent body may have been too small to differentiate, or it may have formed too late to take advantage of heat sources like Al-26 (and there may be other possibilities). We are always looking for material that escaped processing on asteroids to learn about the origin of the solar system. Type 3.00 chondrites are good for doing such studies. CAIs are also important for early solar system studies, and we're fortunate that the meteorites richest in CAIs tend to be low petrologic types that escaped heating on asteroids as well; many carbonaceous chondrites are like this. I hope this is a start at answering your questions.

Oxygen heterogeneity in these objecbulk samplests will be a function of sample size, as fine matrix grains equilibrate much more quickly than coarse ones. If you analyze small aliquants of sample, most UOCs will be heterogeneous. If, on the other hand, we were talking about the O isotope heterogeneity of individual olivine grains, akin to how we measure FeO in olivine, you might be able to devise a metamorphic parameter. But so far, I'm not aware of anybody devising a way to use O isotopes to measure metamorphic grade. The meaning of type 3.00: you said, A subtype of 3.00 means that the material has survived unchanged by heat (radioactive decay, pressure, impact/shock, etc.) or aqueous alteration since its formation. This is incorrect. It means the material is unaffected by thermal metamorphism. Semarkona is shock stage S2, so it has been seen elevated pressures due to impacts on the parent body. It also shows abundant evidence for light aqueous alteration. You can think of all these things as independent processes. Semarkona saw little heat, but got a little shocked and a little bit wet. Many CM chondrites saw little heat, but a lot of water. I would call these CMs type 3.00 as well, but traditional usage has coined another term for really wet chondrites, namely type 2. Oh well. Metamorphically, they are type 3.00. Some chondrites saw little shock and a lot of thermal metamorphism. Anyway, all type 3.00 means is that the object saw little prolonged secondary heating. The parent body may have been too small to differentiate, or it may have formed too late to take advantage of heat sources like Al-26 (and there may be other possibilities). We are always looking for material that escaped processing on asteroids to learn about the origin of the solar system. Type 3.00 chondrites are good for doing such studies. CAIs are also important for early solar system studies, and we're fortunate that the meteorites richest in CAIs tend to be low petrologic types that escaped heating on asteroids as well; many carbonaceous chondrites are like this. I hope this is a start at answering your questions.

Someone asked me to explain the scientific importance of meteoritic material with a 3.00 subtype. Reading through The onset of metamorphism in ordinary and carbonaceous chondrites by Grossman and Brearley 2005, I realized that a key tool used in the analysis of NWA 7731 and NWA 8276 was not present in the literature. So, I'll start with this first part of questions: In my discussions with Dr. Agee, he mentioned that the heterogeneity of the oxygen isotope results is important because it indicates that the material has not been metamorphosed by heat or shock. Any heating would have caused the oxygen to begin to equilibriate. So, is the oxygen isotope analysis something that should be added to the list of factors used in evaluating low sub-types? Or is it a proxy for more complex tests? I am hoping that Karen Ziegler can also add some insights. The second set of questions is perhaps more complex. What is the scientific importance of the 3.00 subtype? I can get this one kicked off, but would appreciate a more nuanced answer than what I can provide. The subtype 3.00 represents the earliest glimpse of the properties of proto- planetary material in our solar system. A subtype of 3.00 means that the material has survived unchanged by heat (radioactive decay, pressure, impact/shock, etc.) or aqueous alteration since its formation. An implication of the unequilibrated nature of this material is that the parent body had to be quite small for it not to differentiate in any way. Though both scientifically important, what different types of insights do we gain from CAIs versus subtype 3.00 material? The answer is I am sure that they complement each other, but in what way. Which is oldest? The rarity of this type of material
[meteorite-list] Looking for info on Lancon
Hello all I have a small piece of Lancon, France 1897 and would like to add some information to it. If anyone has anything on the circumstances of the fall, recovery...anything really I would be much obliged. Coming up quite empty, this is all I have and it seems like there should be more: One or more stones fell in Lancon, after we had heard shots and saw a fireball in the sky. The details of the fall and discovery do not seem to have been recorded. We do know that a harvest worker, Mr. Descordes, who worked for a Lancon farmer found a stone on the ground after the meteorite fall.
