Rock magnetic studies of the CY-4 drillhole through the Troodos ophiolite, Cyprus

Abstract

Rock magnetic properties of 50 specimens from a continuous section through the lower layers of the Troodos ophiolite in the CY-4 drill hole, reveal an alteration and palaeomagnetic history consistent with ocean spreading. Anisotropy of magnetic susceptibility (AMS), low temperature demagnetization (LTD), high temperature demagnetization (TD), distinct Curie and Neel temperatures and hysteresis were the main rock magnetic techniques and were supplemented by thin section microscopy.
