Porosity, bulk density and CaCO3 content of travertines. A new dataset from Rapolano, Canino and Tivoli travertines (Italy)

The dataset presented in this article is used in the Quaternary Science Review research article “Evaluating the geogenic CO2 flux from geothermal areas by analysing Quaternary travertine masses. New data from western Central Italy and review of previous CO2 flux data” [1]. The present data article reports the physical properties and new compositional data of 86 travertine samples from Rapolano, Canino and Tivoli travertine deposits (Italy). The dataset include the following parameters: mass, volume, porosity, bulk density, CaCO3 content and insoluble fraction. The dataset is integrated with the photographic documentation of the sampling areas, the location and the stratigraphic position of each sample.
