Caution ! “Straight application of quantitative methods to identify possible alignments in the geological record may produce mathematically acceptable results but also meaningless from a geological point of view. To avoid this, any attempt at numerical recognition of alignments resulting from a geological process should be supported by field observations. ” http: //blog. potterzot. com/wp-content/uploads/2007/09/garbage_paradigm. gif
