The Acque Albule Basin in Tivoli (Rome, Central Italy) represents one of the largest exposures travertine deposits world. A detailed study Upper Pleistocene Testina travertine, constituting poorly lithified top part Lapis Tiburtinus travertines, is presented. Fieldwork performed an area 10 km2 and petrographic analysis allow recognition six geobodies with different geometries, degree diagenetic...

vartun geothermal region (vgr) is located in west central part of iran, 300 km in the southeast of tehran. vgr area is 277 km2and there are some geothermal surface manifestations such as warm springs and travertine deposits. there are three warm springs which their temperature varies from 35.3 to 43.1 °c. their ph is a little bit acidic and is about 6.1-6.2. based on geothermometery studies var...

We propose the use of cover as a quick, low-resolution proxy for the abundance of microbial species, which reduces polymerase chain reaction bias. We showcase this concept in a computation that uses clone library information from travertine-forming hot springs in Yellowstone National Park to provide estimates of relative covers at different locations within the spring system. Samples were used ...

We present a simple, abstract model for travertine dam formation. The simulation uses a depth-averaged hydrodynamic code, coupled with an empirical precipitation model where surface-normal growth rate is proportional to local flow rate. The dynamics of the resulting formation, coarsening and migration (progradation) of crests is demonstrated and compared with field observations. The local self-...

In the urban sites the lead addition in petrol, as an antidetonation agent, allows pollution of exposed surfaces of buildings, soils and vegetation. In a preliminary way a research work has been carried out simulating lead pollution of the slab surfaces of the Roman-Travertine stone. The Roman-Travertine is a limestone dimensional stone widely employed in Italy especially for dressing of the ol...

Continental carbonates, such as travertines and tufas, formed from CO 2 -rich groundwater degassing it emerges at the Earth’s surface, are often associated with major crustal-scale faults. The Carraclaca site, in Lorca-Totana section of Alhama de Murcia Fault, Spain, presents a complex geomorphological landscape controlled by active tectonics. geology here records interaction between Quaternary...
