Application of mineralogical, petrological and geochemical tools for evaluating the palaeohdrogeological evolution of the PADAMOT study sites [PDF]

open access: yes, 2005
The role of Work Package (WP) 2 of the PADAMOT project – ‘Palaeohydrogeological Data Measurements’ - has been to study late-stage fracture mineral and water samples from groundwater systems in Spain, Sweden, United Kingdom and the Czech Republic, with ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Raw Material Economisation in Aotearoa New Zealand: Evidence for Manufacture and Recycling of Adzes on Ahuahu Great Mercury Island

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Raw materials are used to characterise the early settlement of Aotearoa Te Wai Pounamu New Zealand by Māori. Current models suggest change in raw material use over time occurred in response to changing social organisation and reduced resource availability. However, few studies have examined spatial variation in raw material use.

Fingerprinting stress: stylolite and calcite twinning paleopiezometry revealing the complexity of progressive stress patterns during folding-the case of the Monte Nero anticline in the Apennines, Italy [PDF]

open access: yes, 2016
In this study we show for the first time how quantitative stress estimates can be derived by combining calcite twinning and stylolite roughness stress fingerprinting techniques in a fold-and-thrust belt.

The Domus Nozze D'Argento in Pompeii: Structural Diagnosis Using Geophysical Methods

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Monitoring of ancient buildings is an issue of great interest in view of a proper restoration. This paper describes the noninvasive monitoring of the Domus Nozze D'Argento in Pompeii. The Roman house, as occurred for many other buildings in Pompei, was buried in the ash from the 79 ad eruption of Mount Vesuvius.

Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.
