ABSTRACT Chemically distinctive features such as high salinity, low nutrient contents, and extremes of pH can limit the development of a vegetation cover on soil‐free bare ground. This study synthesises our previous work on the geoecology of numerous chemically distinctive bare sites in the South Island and adds a temporal component within the last ...

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

Tracking Sediment Mixing Along the Lower Danube River From the Carpathians to the Black Sea
ABSTRACT We use detrital zircon U–Pb geochronology as a sediment provenance tracer in modern river sands to better understand how tectonic, climatic, and anthropogenic processes modulate sediment transport dynamics of the Carpathians to the Black Sea source to sink system.

Mayum: an orogenic gold deposit in Tibet, China
Abstract Located in western Tibet, China, the Mayum orogenic gold deposit was discovered in 2002 with estimated resources of > 80 tonnes gold. The gold mineralization is hosted by Neoproterozoic–Cambrian schists, and is controlled by nearly parallel E–W trending bedding-concordant fracture zones.

This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).
