The Multi-Sensor Core Logger Lab focuses on non-destructive analysis on sediment cores and is equipped with:
- Multi-Sensor Core Logger Geotek® (MSCL) which measures non-destructively the attenuation of gamma rays (gamma ray attenuation porosity evaluator, GRAPE), the velocity of compressional waves (P-wave velocities), and the amount of magnetically susceptible material present in the sediment. The MSCL enables a non-destructive mode of measurement on a fully automated system, providing high resolution (sampling interval up to 1mm) whole-core and split-core logging data. It is also equipped with the GeoscanV system, allowing the acquisition of high-resolution photography of sediment cores, by using a digital camera with a dedicated lighting system.
- Standard X-RAY CT system which consists of a cabinet based on a lead-lined steel system designed to fully enclose an X-ray source, detector and core sample to be imaged. The X-ray CT instrument is specifically calibrated for different core samples, and collects images on split or whole core, through plastic or metal liners, and on cores up to 1.5 m long and 5.25 inches in diameter. All X-ray data are acquired in accordance with ASTM D4452-14.
Since 1988, the laboratory, equipped with the Geotek® Multi Sensor Core Logger, has been hosted at OGS, where it has been used for many research and service’s activities.
The Core Logging Lab is now part of a joint laboratories system in which OGS and University of Trieste share spaces and instrumentation for efficient use of research and teaching infrastructure, combining the laboratory facilities for sedimentological analyses of the two institutes.
