Determining the uniaxial compressive strength of intact rock is primary objective a geomechanical project, and reliable estimate in early phases saves time costs for more sophisticated laboratory tests. The problem knowing which correlations between resistance to compression point load index are reliable, those that cover one or several types (depending on type statistical adjustment). In this ...

The study of microbial mats in extreme environments is high scientific interest from geological, ecological, and geomicrobiological aspects. These represent multilayer bio-structures where each taxonomic group dominates a specific vertical layering distribution resulting its growth metabolic activity. In the present study, hot spring environment Aedipsos (Euboea Island, Greece) creation thermog...

results in terms of radon and thoron emissions, travertine and plaster were found to be the most appropriate and inappropriate covering for walls, respectively. furthermore, granite and travertine were discovered to be inappropriate materials for flooring, while plastic floor covering was found suitable. natural ventilation performed better for radon, while artificial ventilation worked better ...

derik geothermal region has area of 242 km2 and is located 10 km to the west of salmas city in west azarbaijan province of iran. the most outstanding surface manifestations of geothermal energy in this region are three warm springs and outcrops of travertine deposits and quaternary basalt outcrops around warm springs. temperature range of warm springs varies from 31 to 32.6 °c. we visited and s...
