As the world's urban population continues to grow, it becomes increasingly imperative to understand the dynamic interactions between human activities and the urban environment. The development of urban environmental geochemistry has yielded a significant volume of scientific information about geochemical phenomena found uniquely in the urban environment, such as the distribution, dispersion, an...

Abstract. Tracing the origin of sediment is needed to improve our knowledge hydro-sedimentary dynamics at catchment scale. Several fingerprinting approaches have been developed provide this crucial information. In particular, spectroscopy provides a rapid, inexpensive and non-destructive alternative technique conventional analysis geochemical properties. Here, we investigated performance four m...

This study aims to account for the petrogenesis and mineralization of pegmatites around Wowyen area, northcentral basement complex,Nigeria. Field studies, petrography whole rock geochemistry (Major oxides were estimated by X-Ray Fluorescence while trace elements Inductively Coupled Plasma Mass Spectrometry) where methods adopted. The area are emplaced in remobilized belt Nigerian Basement compl...

The 9th national conference on applied geochemistry in China will be held Chengdu, Sichuan province, October 2023, hosted by the committee of geochemistry, Chinese Society for Mineralogy, Petrology and Geochemistry (CSMPG) [...]

The impact of pre-Columbian subsistence agriculture on soil nutrient cycling in the American tropics is poorly quantified. Paleolimnological research can address this deficit by documenting the temporal evolution of nutrient cycling in lake watersheds over different time scales. Here we describe our use of a chemical sequential extraction technique adapted from soil fertility research to discer...

A number of hydrocarbon discoveries have been made recently in the Flemish Pass Basin and Central Ridge, offshore Newfoundland, Canada, but there is only limited geological information available. The primary goal this study was to determine sedimentary provenance paleodrainage patterns mudstones sandstones from Upper Jurassic Rankin Formation, including Lower Kimmeridgian Source Rock (organic-r...

Introduction: Terrestrial studies of concretions have been strengthened from the NASA programs, with the study of “blueberries” in the Burns formation discovered by the Mars Exploration Rover (MER) Opportunity. Scientific interest on iron oxide concretions has increased from a point just a decade or two ago, when concretions were viewed simply as geologic “curiosities”. The purpose of this pape...

Long marine sedimentary cores can be effective in paleo-climate reconstruction. The present research aims at analyzing  the temporal variation of temperature as an important climate parameter and also variations in metal concentrations (As, Ba, Cd, Li, Mo, Mg, Mn, Na, Pb, Sr, Zn, Fe, Ca, Al) of two long sedimentary cores at the Persian Gulf back to the Holocene. The obtained results revealed th...
