Chemostratigraphy of Cambro-Ordovician to Silurian Sequences from Block NC186 in the Murzuq Basin, Western Libya

The characterization and correlation of sedimentary sequences based on changes in inorganic geochemical data. The bulk geochemistry of sediments changes in response to subtle changes in mineralogy caused by source composition, facies, weathering or diagenesis. The analytical techniques employed are highly sensitive and the technique can often see correlative features that cannot be detected using E-log data. In some instances, this enables apparently uniform successions to be correlated with confidence.
