Radiocesium released by the severe nuclear accident and weapon test is a hazardous material. Illitic clays play key role in spatial distribution of radiocesium groundwater environments due to selective uptake sites at illite mineral, such as frayed edge sites. However, cesium capabilities illitic are diverse, which could be associated with crystallinity. This study was performed determine evalu...

Fine ware pottery from the Etruscan town of Tarquinia, whose necropolis in inscribed list UNESCO sites, was studied by means near-infrared (NIR) diffuse reflection spectroscopy. The aim to investigate correlation between firing conditions illitic-calcareous local clay, terms temperature and atmosphere, physical properties ceramic paste, usually exploited archaeologists for a classification sher...

Three Ohio soils, Hoytville clay, Brookston silty clay loam, and Wooster silt loam located at various branches of the Ohio Agricultural Research and Development Center, were studied. Bulk samples from each horizon were tested for exchangeable basic cations, pH, sulfuric acid extractable potassium (K+), and particle-size distribution. The surface horizons of each soil were characterized by measu...

The Galápagos archipelago is a well-suited model ecosystem for investigating soil evolution. Here, we study mineral transformations and pedogenesis of the volcanic soils in response to weathering duration (1,500–1,070,000 yr) climate (humid vs. dry). Our results show that pH, electrical conductivity, organic C content, cation exchange capacity (CEC), water retention decreased whereas clay conte...

The usage possibility of 19 composites raw refractory clays from Serbia containing approximately 53.29% SiO2 and 26.73% Al2O3 is presented. sum fluxing oxides was 57.74%, while these materials contained 32% quartz, 29% kaolinite 26% illite–mica. Dilatometry tests revealed a sudden shrinkage with the peak at 1115 °C, owing to formation mullite. refractoriness in range 1581–1718 which classifies ...
