Abstract

Orogenic gold deposits are fundamental to society, industry and academia, but regional factors governing their location remain unclear, making the discovery of new deposits difficult. Spatial analysis of orogenic gold deposits found that deposit clusters have a systematic periodic spacing of 30 to 40 km, with the largest clusters defining rich regions 40 to 100 km long. These spatial patterns predict the location and scale of the geologic factors governing the location of large gold deposits. Analysis of geophysical and geological data from the Yilgarn craton show that orogen-transverse discontinuities adequately explain the location and periodic spacing of orogenic gold deposits.
