The sedimentary succession surveyed in this area presents a continuous exposure up to 600\u202fm thick and comprises both pure and hybrid siliciclastic, carbonate and evaporitic rocks. Reflectance data obtained from this area were processed by <a title=\"Learn more about multivariate analysis\" href=\"https:\/\/www.sciencedirect.com\/topics\/earth-and-planetary-sciences\/multivariate-analysis\">multivariate analysis<\/a>, which demonstrates that almost all of the data variance is represented by the first principal component. Inflections of the scores&#8217; derivatives can be used to identify stratigraphic surfaces and as an indicator of stacking patterns. Overall, these results demonstrate that fast, inexpensive and non-destructive spectral data are useful tools in the fields of <a title=\"Learn more about sedimentology\" href=\"https:\/\/www.sciencedirect.com\/topics\/earth-and-planetary-sciences\/sedimentology\">sedimentology<\/a> and stratigraphy, which have the potential to eventually support more complex and detailed hyperspectral stratigraphy research.<\/p>\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0895981118302335\">Journal of South America Earth Science<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this research was evaluated the potential of using scores derived from spectral data to detect surfaces and stacking patterns in the sedimentary record, and propose a new method for analyzing spectral data.
