A review of the potential for rare earth element resources from European red muds: examples from Seydişehir, Turkey and Parnassus-Giona, Greece [PDF]
ArticleRare earth elements (REE) are viewed as ‘critical metals’ due to a complex array of production and political issues, most notably a near monopoly in supply from China.

Li zoning in zircon as a potential geospeedometer and peak temperature indicator [PDF]
Zircon Li concentrations and δ[superscript 7]Li values may potentially trace crustal recycling because continental and mantle-derived zircons yield distinct values.

Geology, geochemistry and geochronology of the Songwe Hill carbonatite, Malawi [PDF]
Songwe Hill, Malawi, is one of the least studied carbonatites but has now become particularly important as it hosts a relatively large rare earth deposit.

The Material Basis of 18th‐Century Meissen Porcelain
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Exploring Complex Historical Figures through a Modified Critical Making Framework
Abstract This paper examines ‘critical making’ as a framework for exploring complex problems and topics. Critical making combines an iterative process of making with research, reflection and analysis. The authors present a modified critical making process that builds on the reflexive material engagement introduced by the originator of critical making ...

Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Rare earth elements in karst-bauxites: a novel untapped European resource? [PDF]
Karst-bauxite deposits form as a result of the accumulation of residual clay minerals in depressions on a karst limestone surface, and their subsequent lateritic weathering.

ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.
