Description
Summary:The possibility that Citronelle and Hawthorne sediments in peninsular Florida are terrestrial and marine components, respectively, of an extensive delta was considered through statistical studies involving sediment grain sizes and heavy-mineral suites of the formations. A correlation analysis utilizing all measured variables (in pairs) proved to be inconclusive in determining the possible correlation of the formations. A multivariate approach was then undertaken utilizing principal component analysis. From this it was concluded that the Citronelle and Hawthorne formations are not parts of the same massive delta. Sedimentologic characteristics of the Citronelle sediments support the principal component interpretation.
