Multi-element analysis of discrete samples via X-Ray fluorescence or inductively coupled plasma spectrometry is commonly used to characterise the composition of solid geo-materials for environmental geochemical characterisation. Conventional geochemical analysis of individual samples is time consuming and costly, which often results in low...

In circular concrete design, beside cement replacement with more environmentally friendly cement types, there is also an urgent need for sand replacement with fine recycled concrete aggregates (fRCA). The variations in physical and chemical properties of fRCA and lack of standards for their quality evaluation are the main reasons for not yet...

Major reorganizations in climate and tectonic regime occurred in East Asia during the Pleistocene, resulting in large-scale environmental changes. In this paper a detailed geochemical and mineralogical record of these changes is presented from a distal alluvial fan sedimentary sequence in the northern Weihe Basin. We established that, in...

OMEGA/Mars Express hyperspectral imagery is an excellent source of data for exploring the surface composition of the planet Mars. Compared to terrestrial hyperspectral imagery, the data are challenging to work with; scene-specific transmission models are lacking, spectral features are shallow making them difficult to detect, and field data for...

Having been inspired by the leaflet 'Natuursteen in Maastricht. Aardrijkskunde in een oude stad', written by P.J. Felder and published in 1977, we here present descriptions of the main types of natural stones applied in the city of Maastricht. A concise overview of the provenance area, mineralogy and physical properties of a selection of so...

In most cases, CO2 captured from power plants or large industrial sources contains impurities. As purification of the stream is energy and cost intensive it is necessary to allow a certain level of impurities. The effects of impurities on (short- and long-term) geological storage are, however, uncertain. In this work, geochemical modelling with...

Over the past few years several geochemical evaluations of CO2 storage in Dutch potential reservoirs are carried out, including predictions of the short- and long-term impact of CO2 on the reservoir using geochemical modelling. The initial mineralogy of the reservoir is frequently obtained from core analysis and is then used to compute the...

Pseudoxantoma elasticum (PXE) is a rare chromosomal disorder that results in mineralization of elastic fibers, especially in the skin, eye, and cardiovascular system. Recently, PXE has been associated with testicular microlithiasis (TM),1 which itself might be associated with testicular malignancy.2 Here we report on a 9-year-old boy with PXE...

With various low-temperature experiments performed on magnetic mineral extracts of marine sedimentary deposits from the Argentine continental slope near the Rio de la Plata estuary, a so far unreported style of partial magnetic self-reversal has been detected. In these sediments the sulphate-methane transition (SMT) zone is situated at depths...

Laboratory weathering tests are important in the field of restoration as they provide a means of estimating, in a relatively short time, the longer-term performance of conservation materials when applied in practice. Accelerated tests to simulate the damage caused to porous materials by soluble salts such as sodium sulphate are well known and...

Rhenish tuffs from the volcanic Eifel region, Germany, have widely been used as building stone in the Netherlands. Different kinds of tuff (Römer, Weiberner, Ettringer, Riedener) show different kinds of decay, and also within each group, remarkable differences in weathering behaviour occur. In the present study, a short introduction is given to...
