Reverse and Normal Remanent Magnetization in Hydrothermal Veins

Abstract

AN attempt has been made to apply the measurements of the direction of natural remanent magnetization to the age determinations of epigenetic hydrothermal mineralization. The investigation of materials from Czechoslovakian hydrothermal deposits has brought positive results which have changed some of the previous opinions concerning metallogenetic problems in Czechoslovakia¹. The work was based on several scores of hydrothermal deposits from four metallogenic areas in the West Carpathians and in the Czech Massif. As a comparative geochronological scale for age-determinations the polar wandering curve computed in the way published by Creer et al.² was used. In the hydrothermal mineral deposits of the Carpathian System the parameters introduced by Blackett et al.³, particularly the so-called divergence and inclination difference of remanent magnetization, were also used.
