- Abstract
- An enigmatic, c. 2 km-long and 15 m-high travertine ridge, the Colle Fiorito ridge, occurs in the northwestern
sector of the Tivoli travertine plateau, central Italy. The main questions addressed in this paper concern the
origin and mode of growth of this prominent ridge. The presence of active structures beneath the studied
ridge is inferred by recent and past earthquakes located at shallow depths immediately beneath Colle Fiorito.
To understand the surficial structure of the Colle Fiorito ridge and the travertine depositional environment,
we constructed a 10 m-resolution DEM, analyzed recent and past aerial photographs, and conducted field
surveys and meso- to micro-scale sedimentological analyses. To understand the ridge subsurface structure,
we studied a set of 32 stratigraphic well logs available from previous works and from the local decorative
stone industry, and realized a 2D electrical resistivity tomography (ERT) across the ridge. Results show a gentle
antiformal structure affected by subvertical zones of strata discontinuity. The Colle Fiorito structure is
interpreted as a previously-unknown fissure ridge travertine grown at the edge of the Tivoli travertine plateau,
perhaps when the volumetric deposition rate reached its climax in the plateau for the abundance of
fluid discharge and the rise of the water table. Such a fluid pressure may have activated the faults and fractures
beneath Colle Fiorito, thus opening new pathways for the ascension of geothermal fluids toward the
surface. (literal)
