AFDave,
Let's kick it up a notch and start putting some of the pieces of the sciences together to get a clearer picture of what is going on in Isochrons.
You accept the science of crystalization. | Quote | | In general, I (and every creationist I know) accept all science which involves repeatable, testable events. Crystal formation and many other phenomena fall into this category. What we do not necessarily accept is hypothetical stuff which cannot be tested reliably,{snip} |
I asked this question because I wanted a baseline of agreement for our discussion.
I'm going to use an example at University of Wisconsin-River Falls Dept. of Planet and Earth Sciences. Nothing special about this selection, just near the top of the Google search for "Olivine mineral formation". One member of the faculty is a PhD of geology in the department. Who he is doesn't matter for my point, BUT he has co-authored an article about the subject we are talking about, BUT we won't discuss ages or time just yet. I'm just showing that this particular reference is valid to our discussion. | Quote | | {snip}, 1976, "Rb-Sr Geochronology of Granite Gneiss from Horse Creek, Tobacco Root Mountains of Montana", Geochron West, Summer, p. 49. |
The department has catalogued a lot of Wisconsin minerals but I want to point to Olivine specifically since this mineral is found in magmas AND in chondritic meteorites (remember the Minster graph?). The Olivine page lists the identified locations of Olivine found in Wisconsin. The entries are by county and indicate platte map references for location so any other geologist who is searching for this particular mineral can "find it quite easily" (a relative statement I'm sure). Notice that the Olivine page (and the other mineral pages) don't mention age or time, only location and geographic structure. The site also has a bibliography of numerous references here, here, and here.
The Olivine page also has this heading: OLIVINE (Mg,Fe)2SiO4 Orthorhombic. Ignore the chemical formulae for now, we can get to that later. However, notice the "Orthorhomibic" entry because this describes the crystal structure of Olivine. In fact, almost all the entries in the list of minerals have a heading with a specified crystal structure of the mineral.
So.... Olivine is a crystaline mineral with orthorhombic structure found in numerous places in Wisconsin and catalogued extensively. Nothing hypothetical about this information that I can see. I'm going to end my boring entry right now since there is enough corroberrated information above to ask a NOT-SO-STUPID question.
AFDave,
Do you agree that Olivine is formed according to the science of crystal formation?
If we can agree on the structural mechanics of Olivine then we can start on the chemistry. Are you still game to continue with discussing Isochrons?
