Multi-element abundances in twenty-four samples from the Serra Geral continental flood basalt system (Parana Basin) were determined by INAA to assess the trace element signature of primary magmatric sources. Isotopic Sr and Nd data were obtained on a 24-sample composite and three individual samples of the suite to constrain the influences of older enriched material. Twenty basaltic samples have...

Flood simulation models can provide practitioners of Flood Disaster Management with sophisticated estimates of floods. Despite the advantages that flood simulation modeling may provide, experiences have proven that these models are of limited use. Until now, this problem has mainly been investigated by evaluations of which information is demanded by decision-makers versus what models can actual...

Detection of Hadean isotopic signatures within modern ocean island basalts (OIB) has greatly influenced understanding Earth's earliest history and long-term dynamics. However, a relationship between two tools for studying early Earth processes, the short-lived 146Sm-142Nd 182Hf-182W systems, not been established in this context. The differing chemical behavior these systems means that they are ...

A number of hedonic property pricing studies of flood risk indicate that properties within a designated higher flood risk zone sell for a lower price than an equivalent property outside of it. However, often the homes most at flood risk are also the most desirable in terms of their proximity to the water, and this concurrent existence of positive water-related amenities and negative flood risk ...

Abstract A large compilation of quality-curated major and trace element data has been assembled to investigate how patterns mafic ultramafic magmas have varied with time through particular settings from the Archean Phanerozoic, primary objective being recognise at what times variation emerge, similar these are baseline sets representing tectonic in modern Earth. The most informative combination...

[1] The experimentally determined relationship between atmospheric pCO2 and plant stomata has been used to interpret large but transient changes in atmospheric composition, such as may have resulted from the eruptions of flood basalt. However, this relationship has not been tested in the field, i.e. in the vicinity of active volcanoes, to examine the specific effects of volcanogenic emissions. ...

The 1.88 km diameter Lonar impact crater formed 570 ka ago and is an almost circular depression hosted entirely in the Poladpur suite of the 65 Ma old basalts of the Deccan Traps. To understand the effects of impact cratering on basaltic targets, commonly found on the surfaces of inner Solar System planetary bodies, major and trace element concentrations as well as Nd and Sr isotopic compositio...
