Evidence for ID and creationrapid geologic processesYOu've taken excellent pictures of fold interference patterns. These are well-known to structural geologists and result from multiple folding events usually separated in time. Rather than 'fast' processes, the evidence you document is indicative of changes occurring over vast time periods including multiple episodes of deformation FOLLOWING deposition of these rocks. In essence you provide evidence for at LEAST (1) Deposition of the rocks (2) Deep burial of the rocks (3) Deformation event 1 producing the initial folds. This happened at high P-T conditions causing the rocks to behave plastically. (4) A second deformation event that folded the folds also at high P-T conditions. (5) You mention cracks in the rocks which represents yet a third brittle type of deformation meaning these metamorphic rocks were uplifted into the brittle zone. (6) erosion. to present day levels Basically, you've provided evidence for long, not short time periods. Nice photos though! -E Here are some other examples of refolded folds http://www.nbmg.unr.edu/slides/ggn/18.htm http://www.ualberta.ca/~jwaldron/galler ... olds3.html |
