How the geo strata are identified as time periods

Fine by me, so I'll just suggest that radiometric dating should be included.--Percy

Hi Faith,Sorry to butt in, and I'm going suggest that everyone except Jar butt out, but I just wanted to quickly suggest that you temporarily suspend disbelief and avoid seeking creationist rebuttals. Raising issues and asking questions is part of the process, but the explanation of the analysis of sedimentary layers from the perspective of the science of geology will never be completed if you approach it like a debate. Entire threads have been spent debating Berthault, and other entire threads have been spent debating Mt. Saint Helens. I can't see how any progress can be made if the thread turns to discuss such topics. I'm sure you're very curious about them, but I don't believe that examining creationist claims about them while still ignorant of basic geological principles would be helpful. Just my opinion...--Percy

Okay, let's throw Jar out, but let's limit this. My reaction to this thread is that it's a mess. AdminNosy requested that participation be limited, and this was followed by a number of posts tugging in every different direction. They were all well-intentioned, but a cacophony is not conducive to learning.So pick someone, just one person, to answer your questions. Ah, I see you've chosen Coragyps or Jazzns. Good. Let's see if they accept.I still suggest that you limit yourself to asking questions about things you don't understand or want to know more about, but not seek creationist rebuttals of things you find difficult to accept. Instead seek to understand them better.--PercyEdited by Percy, : Respond to Faith's edit.

I'm not accusing you of anything. I merely described what you did in Message 26, which was to respond to Jar's statement of the principle of superposition with this: My suggestion was that you would learn more by not seeking out creationist rebuttals like this one to what people present in this thread. I think you would learn much more by posting your own reactions and questions with the goal of understanding (not accepting, just understanding) basic geological principles related to sedimentary layers.I further suggest that you leave aside from this thread your tendency to seek offense at every turn. If you want to complain about mistreatment, such as people accusing you of things you didn't do, then please take it to the appropriate thread. Please allow this thread to focus on the topic.--Percy

Hi Jazzns,A couple things in the first para looked funny to me, are these what you really meant to say? Did you mean to say, "Settling *doesn't*..." Huh? Maybe "right" should have appeared after "seem"?--Percy

Sorry to butt in again, just a quick question. Hoover dam was built with cooling water pipes embedded in the concrete. Without them the concrete would have taken around 400 years to cool. Large masses of hot rock take long time periods to cool. The larger the mass, the longer it takes.How long does it take plutons and batholiths the size of mountain ranges to cool to the same temperature as the surrounding rock? Seems like it might be yet another method placing a minimum age on the earth. This isn't directly relevant to this thread, but knowing the approximate time scales they take to cool within the earth would be very useful in dating discussions.--Percy

This thread is being used for explaining how geologists associate layers with time periods, so questions about this process is what's appropriate here. If you'd instead like to challenge the views of modern geology on the formational processes of geologic layers then you should probably find a more appropriate thread, or perhaps propose a new one.--Percy
