Previous blog posts have highlighted the importance of loess as an indicator of climate and environmental changes in the past. These posts showed the relevance of loess deposits as  archives of Pleistocene climates and environments, the importance of using novel approaches in mapping these and other Quaternary-related sediments,  the aspects of dating loess deposits, as well as the peculiarities o ...[Read More]

Name of proxy detrital zircon geochronology Type of record provenance proxy Paleoenvironment any sedimentary environment in a geologically diverse and diagnostic area Period of time investigated any Period of the geological timescale of the Earth, during which sedimentary deposits were formed   How does it work? Igneous rocks form through assemblages of minerals crystallising from melt. While ...[Read More]
