Got it straight on where the intial daugher ratio comes from now, Davie-doofus? You were wrong about us assuming it, weren't you!
Learned anything about chemistry and soldification kinetics?

Your fantasies are not evidence. We have analyzed many meteorites. See Radioisotopic evidences for age of earth (and solar system) for a table of many meteorite analyses (at the end).

"Really small" is a relative term, meaningless without a referent. It's gigantic relative to the sensitivity, precision, and accuracy of the instrumentation, which arguably is the one realistic referent. It's not "really small" relative to the total range of observed values, being approximately 1/2 the range we see and much more than 1/2 of the most commonly encountered ranges. So, Davie-piddles, "really small" relative to what?

We've already pointed out the problems with Google Scholar searches for such counting, not the least of which is the choice of keywords. Boots on the ground, Davie-doodles. That's the only way.

Geez, Davie-moron, I just noticed your extreme dishonesty in your Google search. You almost slipped that one by!!
| Quote | Google Scholar All articles
Recent articles Results 1 - 10 of about 11,300 for whole rock age. 1981-1990
Recent articles Results 1 - 10 of about 478 for mineral isochron 1981-1990 |
You searched for "whole rock age", picking up all sorts of dating methods, but "mineral isochron", trying to limit it to isochrons! Naughty, naughty, Davie-dork! Of course, I don't think that a Google Scholar search is particularly meaningful, but let's see why Davie did that:
Google Scholar, all articles, 1981-1990:
| Code Sample |
"whole rock isochron" (phrase) 145
whole rock isochron (all words) 443
"mineral isochron" (phrase) 41
mineral isochron (all words) 478
"whole rock age" (phrase) 103
whole rock age (all words) 11,600
"mineral age" (phrase) 69
mineral age (all words) 12,400
|
So, Davie-doodles, you didn't like that result, did you? If you believe in such Google Scholar searches, your (and Arndts and Overns' ) claim is refuted. No matter how you slice it, comparing comparable searches doesn't come close to 90% whole rock. So you had to do something fraudulent, didn't you? That explains your love for Snelling; frauds of a feather flock together.

Since there are 23 independent meteorites than this fits my definition of MANY. I'll assume you agree with me on this definition and carry on.
