BACKGROUND Building materials and the ventilation rate of a building are two main factors influencing indoor radon and thoron levels (two radioactive gases which have the most important role in human natural radiation exposure within dwellings). OBJECTIVES This analytical descriptive study was intended to determine the relationship between indoor radon and thoron concentrations and the buildi...

Abstract In March 2018, part of the travertine barrier at Milino Lake, in Plitvice Lakes National Park Croatia, broke off, significantly altering flow water over barrier. Encouraged by this event, Faculty Civil Engineering Rijeka conducted a monitoring and analysis erosion dynamics barriers on Lakes. Within project, analyses stability were carried out. To author's knowledge, physical mechanical...

The Tibetan Plateau is known as the core area of third pole Earth and a key for global climate change research. This study uses Zabuye Salt Lake travertine dam research object U–Th dating chronological framework proposes that carbon oxygen isotopes can be used precipitation index through analysis hydrogen spring water, petrology, mineralogy, travertine. records over last 800 years show dry cond...

Banded travertines are important parts of fissure ridge systems, but studies on geochemical characterization banded limited. This study investigated the lithofacies and stable carbon oxygen isotopic features from Xiagei (southwestern China) to examine their formation mechanisms. Petrographic analyses revealed two lithotypes: thick-laminated palisade crystalline crust thin-laminated composite cr...

The Skellefte mining District is located in northern Sweden and comprises Palaeoproterozoic, metamorphosed, supracrustal rocks and associated intrusive rocks, which are all host to several ore deposits. Modelling was performed in the GoCAD software platform, using structural geology and petrology as well as magnetic, gravity, seismic, electric and electromagnetic geophysical data, in order to p...
