A multivariate model for mineral endowment.

TL;DRAbstract

This study proposes a multivariate statistical model for mineral endowment and estimates the model parameters for epithermal precious metal deposits in the Walker Lake 1° x 2° quadrangle of Nevada and California. The multiple regression model developed in this study is utilized to describe mineral endowment as a function of quantified geology. Geology and mineral endowment are quantified on consistent geological areas or intrinsic samples, which represent a homogenous multivariate population whose members are statistically independent. A new, geologically-defined mineral endowment descriptor, volume of mineralized rock (VMR), is proposed, which is defined as the total volume of rock exhibiting anomalous concentrations of metallic and non-metallic minerals occurring within a particular type of mineral deposit present above a specified maximum depth in the crust of a region. The proposed model incorporates an externally-defined measure of mineral exploration completeness in an exploratio
