A CRITICISM OF THE HOLM-MUNKSGAARD OXYGEN AND STRONTIUM ISOTOPE STUDY OF THE VULSINIAN DISTRICT (CENTRAL ITALY)
No full textStable isotope geochemistry and structural elements of the Sabina region (Central Apennines, Italy)
No full textStable isotope geochemistry and examination of meso- and microstructures show that strain conditions differed through the course of tectonic history. Carbon and oxygen isotope analyses of the calcite-filled extensional fractures, the sigmoidal veins present between stylolitic cleavage surfaces, and fault plane surfaces with differing motion, demonstrate those different geneses. -from Author

No full textProvenance determination of travertine from Umbria (Italy) Preliminary results of a multimethod - analytical approach
No full textA multi-method analytical approach was applied in the characterization
of travertines from different monuments in Umbria
(Central Italy), with the aim of obtaining archaeometric information
on provenance. Preliminary statistical analysis of whole rock
geochemical data was employed to discriminate travertines of different
monuments in Umbria, and in one case it led to the identification
of two distinct provenances, local and from Latium, for
the travertines employed in the same monument. Further information
on provenance was obtained by combining geochemical
and isotopic compositions with textural data in the comparison
between monuments and reference quarry samples. The obtained
results show that the intrinsic variability of travertine within the
same litholog ical formation, though large, can be lower than that
observed between different travertine formations. This makes it
possible to determine the provenance of the stone, providing the
source areas have been adequately selected and characterized
