Alteration and the Magnetic Properties of Deep-Seated MarineBasement from the Josephine Ophiolite

低温和高温热液蚀变对海洋岩石中钛磁铁矿的磁效应尚不清楚。本文研究约瑟芬蛇绿岩的下地壳岩石，重点研究蚀变对其磁性的影响。这项研究将有助于更好地理解岩脉和岩脉对磁异常的重要性。

The magnetic effects of low and high temperature hydrothermal alteration on titanomagnetite in oceanic rocks are poorly understoods. The objective of this study is to examine the lower crust rocks of Josephine Ophiolite with empkhasis on the alteration effects on magnetic properties. The study will lead to a better understanding of the importance of dykes and gobbros on magnetic anomalies.
