Abstract

In the simplest type of net, conjugate shear fractures are more or less evenly spaced and those of each set are more or less parallel to one another. Extending the network beyond and between known veins provides a basis for prospecting. More complex nets may involve curving fractures and spacings that change as veins are followed along their strike. Indications of mineralization have been found by this technique in the Jihlava mining district (Czechoslovakia).
