Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Flow resistance evaluation in gravel- and boulder- bed

open access: yesShui kexue jinzhan, 2020
The standard exponential and logarithmic flow resistance laws in shallow streams with gravel- and boulder- bed cannot be adapted. Field investigations suggest that the flow velocity near gravel bed is lower than that of the upper flow, similarly to the ...

Contribution to the floristic knowledge of the head of the Po Valley (Piedmont, north Italy) [PDF]

open access: yesItalian Botanist, 2018
In 2014, the annual field trip of the working group for Floristics, Systematics, and Evolution of the Italian Botanical Society was held in Piemonte (northern Italy), at the head of the Po Valley. This valley, at whose extremity is located the Monviso (3,

Seismic anisotropy across Adria plate, from the Apennines to the Dinarides

open access: yesFrontiers in Earth Science, 2022
The Adria microplate has the particular feature to be involved in two subduction systems with slab dipping in opposite directions, one toward west beneath the Apennines and the other to the east beneath the Dinarides.

Diurnal and semidiurnal cyclicity of Radon (222Rn) in groundwater, Giardino Spring, Central Apennines, Italy [PDF]

open access: yes, 2018
Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including earthquakes. In this work, Rn concentrations in groundwater were

Growth and dissection of a fold and thrust belt: the geological record of the High Agri Valley, Italy

open access: yesJournal of Maps, 2020
We present a 130 km2 wide geological map for the NE side of the fault-bounded High Agri Valley Southern Italy, that formed in the Quaternary in response to extensional tectonics dissecting the folds and thrusts of the Lucanian Apennine.

Geology of the Mt. Cosce sector (Narni Ridge, Central Apennines, Italy) [PDF]

open access: yes, 2016
This paper is companion to a 1:15,000 scale geological map of the southern sector of the Narni Range in Central Italy. This sector of the Apenninic Chain was affected by the western Tethyan rifting stage during the Early Jurassic, and the inherited ...
