X-ray techniques and observations on distal Bengal Fan sediments cored during Leg 116

Abstract

A simple, nondestructive procedure for sampling cores for shipboard X-raying is outlined. Subtle and hidden features of distal Bengal Fan turbidites and bioturbidites revealed by X-raying include: the nature of bed contacts, lamination in muds, extensive bioturbation that does not destroy lamination, grading and distinct contacts, and the distribution of authigenic iron sulfides. Coring disturbance caused by rotary coring operations is also readily observed on X-rays. -from Authors
