Non-destructive multiple approaches to interpret the preservation of plant fossils: implications for calcium-rich permineralizations

From: Journal of the Geological Society | Date: November 1, 2003| Author: | Copyright information

Abstract: Permineralizcd fossil coniferous woods from the Pliocene of Dunarobba, Umbria, Italy, and the jurassic of Swindon, Wiltshire, England, were studied using non-destructive techniques on uncoated polished thin sections to elucidate their preservational history. Specimens were observed using transmitted light, polarized light, reflected light under oil, and cathodoluminescence. Selected areas were studied using a variable pressure SEM in backscattered electron mode. This allowed uncoated specimens to be examined and elemental distributions to be determined using an energy dispersive ...
