Geologic time rock dating

Events in the Basin and Range and along the West Coast have also influenced Colorado's physical development, particularly from ~80 Ma on.Let's pause now to get oriented within and around our region of interest.Geologic understanding requires careful attention to time as well as three-dimensional space, so we'd better stop here first.If you're unfamiliar with geologic time terminology and abbreviations, take that detour now.The wavy fabric indicates solid flow at mid-crustal temperatures of 400-500C.To recast barely conceivable geologic time intervals in a more familiar format, they'll also appear from time to time as military hours in a single 24-hour day (and all-nighter) of creation beginning at the planet's formation and ending with the here and now.The table below collects the links to these headers.

That's true everywhere, of course, but it goes double here.Most of them cluster around the intersection of these two profound lineaments, both which almost certainly cut the full thickness of the lithosphere.This telling elevation distribution reflects a powerful synergy between truly ancient plate processes driven by the cooling of the earth in the presence of gravity and ongoing mantle processes driven by Lord knows what.I've attempted to point out the most significant unknowns and disagreements, but often, rightly or wrongly, I've simply taken sides.If you take nothing else away from this humble attempt, please consider this: Of Colorado's 55 Fourteeners, all but 2 (Longs Peak and Pikes Peak) lie either along the Colorado Mineral Belt or on the shoulders of the Rio Grande Rift.

Colorado's also part of an immense, heterogeneous and longstanding tectonic upland covering the entire western third of the United States and ultimately can only be understood in that context.

In the above chart, years are displayed in scientific notation i.e. 1 x 10 6 = 1 million; 1 x 10 9 = 1 billion, etc. All of the above isotopes are readily produced in nuclear reactors, so there is every reason to believe that they were formed along with stable isotopes, in roughly the same abundance as nearby stable isotopes of similar.
