Tracing Raw Material Sources of Prehistoric Stone Artefacts by Non-Invasive Techniques: The Case of the Early Bronze Age (3rd Mill. BCE) Site of Vathy, Astypalaia, Greece by Maria Kokkaliari, Eugenia Adam, Andreas Vlachopoulos, Ioannis Iliopoulos

“…The stone artefacts made of local geo-materials consist mainly of calcitic sandstone, shale, marl, and limestone/marble, comprising the largest part of the lithological formations of the island, as well as pumice and volcanic rocks of varying chemical composition. By means of a portable microscope and NIR spectroscopy, we were further able to identify allogenic geo-materials including chalcedony, mica schist, bauxite and meta-bauxite, steatite, and paragonite. …”

Relationships between soils and productivity of NSW blackbutt (Eucalyptus pilularis Sm.) forests by John Turner

“…It was estimated that if the quantity of P and Ca accumulated in stem biomass at age 50 years were removed it would only potentially affect growth by 0.48% on soils derived from sedimentary rocks but by 12% on granitic soils. The information may used to develop an estimate of sensitively to change in site as a result of management practices. …”

The analysis of the fault system in the passive rift basin—an example from the Muglad Basin, central Africa by Yanqi Wang, Guangya Zhang, Guoqi Wei, Zhuxin Chen, Rong Ren, Lining Wang, Yuqing Zhang

“…Previous studies have primarily focused on the division of fault level and their role in hydrocarbon accumulation, but have not delved into the geometric features and evolution of the fault system across the entire Fula sag.Methods: In this paper, we systematically studied the fault system and its hydrocarbon control within the sag using petroleum seismic reflection profiles, as well as logging data.Results and Discussion: And the conclusions are as followed: 1) tectonic features in diverse areas of the Fula sag vary significantly from a shovel-like half-graben to the asymmetric graben, and faults in the study area can be classified into five combination features. 2) Three complete rift-sag cycles have developed since the early Cretaceous, with continuously active faults controlling the formation of “inherited” sag. 3) The strong activity of faults in the first and second riftting period led to the development of mainly AG-Formation source rocks and middle reservoir-forming assemblages in the Fula sag. …”
