Discriminant Analysis Of Xrf Data From Sandstones Of Like Facies And Appearance: A Method For Identifying A Regional Unconformity, Paleotopography,And Diagenetic Histories, Stephen Paul Phillips

Theses and Dissertations

The placement of an unconformable surface within a stratal succession affects the interpreted thickness of units and sequences in contact with that surface. Unit thickness influences the interpretation of basin subsidence, paleotopography, diagenesis, and depositional style. Accurate placement of an unconformity results in true formational thicknesses for formations associated with that unconformity. True thicknesses aid in producing more precise surface to subsurface correlations, isopach maps, and paleogeographic maps. An unconformity may be difficult to identify in the stratal succession due to similar rocks above and below the unconformity and the presence of multiple candidate surfaces. Using statistical discriminant analysis of …
