Rocks with negative cerium anomalies, dredged from Shatsky Rise

Abstract

Some of basaltic rocks dredged from Shatsky Rise have large negative cerium anomalies. Also these samples have a wide variation in manganese content, and there appears to be some relationship between the extent of cerium anomaly and the manganese content. These observations may be of much significance for discussions of manganese nodule genesis. © 1975, GEOCHEMICAL SOCIETY OF JAPAN. All rights reserved.
