Title

Modal mineralogy data of iceberg-rafted debris (NERC Grant NE/T006609/1)

Abstract

Modal mineralogy data of iceberg-rafted debris deposited at IODP Site U1538 in the Scotia Sea 1.2 million years ago based on QEMSCAN® analyses, which infer minerals from chemistry

Quality and validity

Lineage

We mounted ∼1 g of the sand (>63-μm) fraction of each sample in a 30-mm diameter (15-mm thick) epoxy resin block. Sample measurement and data processing were undertaken using the software packages iMeasure version 4.2SR1 and iDiscover 4.2SR1 and 4.3 (Rollinson et al., 2011). The QEMSCAN® settings used 25kV, 5nA, a 1000 X-ray count rate per pixel, a working distance of ∼22-mm under high vacuum and beam calibration every 30 min. We used the software's fieldscan measurement mode to analyze each sample (Pirrie & Rollinson, 2011) at an X-ray resolution/pixel spacing of 8-μm and a 1500-μm2 field size (at x46 magnification).
