Innovations in mineral exploration Targets methods and

The most widely-used gemstone exploration techniques today are ground-penetrating radar known as GPR trace-element analysis which involves seeking signature elements as clues to where gems may lie and use of a device called a terra thumper which identifies differences in the structure of the host rock through seismic analysis
