A Methodology for the Geostatistical Characterization and Exploratory Data Analysis of Sand and Gravel Deposits

摘要

Spatial relationships among physical and chemical properties pertinent to economic development of sand and gravel deposits have been little studied. Models need to address trends or zonation of material properties applicable to mine evaluation and planning or as a guide among deposits for use in regional assessment Models can then be utilized to design sampling programs to optimize additional data acquisition. Development of a preliminary methodology in the lower Boise River Valley, western Idaho, will utilize historical and recent data from a terrace-gravel deposit. Classical statistics and techniques of spatial data analysis will be evaluated as a precursor to formal geostatistical evaluation.
