Speleothems are carbonate cave deposits that can preserve a geochemical record of local climate as they grow. Oxygen isotope ratios and trace element concentrations in speleothem calcite provide important continental proxies of past climate change. Conventionally, geochemical an…

The issue of granite petrogenesis plays a key role in our overall understanding of the growth and differentiation of continents, as well as in our ability to unravel the tectonic histories of orogenic belts. Granites are ubiquitous magmatic products found in almost all tectonic …
Pyrrhotite and pyrite commonly contain minor quantities of cobalt, nickel, arsenic and other trace elements, which reflect major effects of source lithology and fluid chemistry, and subordinate effects relating to local processes. Electron probe micro-analyses (EPMA) of silicate…
The potential of Arctica islandica, a long lived marine bivalve with a lifespan of over 300 years, to reconstruct a high resolution (sub-annual) climate record is explored in this thesis. Fluctuations in trace element and isotopic data from live-collected specimens from Irvine B…
Also aged bottles are safer to use than new bottles because their chemical leaching was found to be lower than that of new bottles. This study recommends the reassessment of the absence of international guidelines for acetaldehyde in water and foods. The study also recommends th…
As part of the INTAS funded CLIMAN project into Holocene climatic variability and the evolution of human settlement in the Aral Sea basin, fossil diatoms obtained from Chernyshov Bay in the Aral Sea have been examined in order to reconstruct conductivity and lake level change si…
An analytical method that uses a minimum150 ìL of human plasma samples for the trace elements Fe, Cu, Zn, Mg and ultratrace elements Mn, Co, Cd, Pb was developed. The method was evaluated using both high resolution sector field (ICP-SFMS) and quadrupole (ICP-QMS) inductively cou…
In many coastal systems, freshwater inputs influence the physical and chemical environment of estuarine organisms through changes in flow patterns, salinity, and conveyance of wastewater pollution. In areas with harvestable commercial fishery stocks, freshwater inputs may also p…
In 2015, Illinois changed size and harvest limits for catfishes (blue catfish Ictalurus furcatus, flathead catfish Pylodictis olivaris, and channel catfish Ictalurus punctatus) in the Ohio River to match those of neighboring states in order to provide continuity of the regulatio…
The Cripple Creek alkaline igneous rock-related low-sulfidation epithermal gold telluride deposit is hosted in a 10 km wide Oligocene alkaline volcanic diatreme in Proterozoic rocks. Periods of phreatic eruptions and progressively more mafic alkaline magma emplacement created th…
The trachytic Campanian Ignimbrite was emplaced at 39.8 ka near Naples, Italy, in the largest European eruption of the past 200 ka. Many factors, including the far-reaching extent of deposits, with co-ignimbrite fallout found as far away as Russia, indicate emplacement via a dil…
