摘要:Abstract(#br)The chemical weathering rate of silicates is a key parameter of several geochemical processes; however, the long-term field measurement of these rates remains challenging. Currently, there are several methods for quantifying field weathering rates, but each pres...

摘要:Abstract(#br)Mineral soil constituents play an important role in the storage/release of nutrients due to their ability to adsorb and desorb cations. Phyllosilicate minerals are particularly reactive due to their small size and high specific surface area (up to ∼800 m 2 ...

摘要:Abstract(#br)This study presents U-Th-Ra isotope data for soils, soil grain size fractions, soil solutions, throughfall, rainwater and tree samples from two experimental plots under spruce and beech trees, in the Strengbach catchment (France) that highlight the importance of the ...

摘要:Abstract(#br)The impact of mineralogical sorting on U-Th-Ra variations observed for the Ganga sediments in the Himalayan alluvial plain due to transport and deposition processes highlights the importance to better understand the U-series isotopic system in Himalayan minerals...

摘要:Abstract(#br)Our study deals with the part played by bedrock grain size on soil formation rates. U- and Th-series disequilibria were measured in two soil profiles developed from two different facies of the same bedrock, i.e., fine and coarse grain size granites, in the geomo...

摘要:Abstract(#br)Over the last decades, the U- and Th-series nuclides were successfully used to determine weathering rates in various environments. The objective of this study is to assess the potential impact of the vegetation change on the U- and Th-series signal recorded in f...

摘要:Abstract(#br)Spheroidal weathering that forms corestone-shell complexes (hereafter, CSCs) is a common form of chemical weathering of rocks. In this study, we combine mineralogical and geochemical measurements with K-Ar dating and uranium series (U-series) analysis with the g...

摘要:Abstract(#br)Understanding the origin of U–Th–Ra variations in the Ganga river sediments is a prerequisite for correctly using U-series nuclides to constrain the sediment transport times in Himalayan rivers. For this purpose, U, Th, and Ra concentrations, along with 238...

摘要:Abstract(#br)The atmospheric dust contribution to U-series nuclides in soils is evaluated by analyzing two soil and paleo-soil (< 10 ka) profiles from the Mount Cameroon volcano where Sr–Nd–Pb fingerprints are clearly affected by Saharan dust accretion. The comparison of mea...

摘要:Abstract(#br)New fossil material was recovered at Tam Hang during the second fieldwork season conducted in 2007, by a Lao-French-American team. The Tam Hang site is located in northern Laos, in the Hua Pan province, about 260 km from Vientiane. The breccias of the Tam Hang S...
