A database consisting of 163 data on the uranium content and 234U/238U initial activity ratio 15 Italian travertine calcareous tufa sites was created using from relevant literature. Using a graphical method, were interpreted considering U geochemistry in natural environments as well geological, hydrogeological hydrogeochemical settings each site. The appear to be affected by different factors, ...

This work presents a sinkhole susceptibility and risk assessment mapping in Guidonia-Bagni di Tivoli plain (Italy), travertine sinkhole-prone area where sudden occurrences of sinkholes have happened past recent times. We collected point-like inventory we considered series different sinkhole-controlling precursory factors over the study area, related to its geo-litho-hydrological setting terrain...

Uniaxial compressive strength (UCS) and elastic properties of rocks play a major and vital role for the design of any engineering structure. The specimen diameter size is one of the main factors that influencing on UCS, elasticity modulus and Poisson’s ratio (E and υ). Here, an attempt has been made to investigate the effect of specimen diameter size on UCS, E and υ. Moreover, we studied the co...
