Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]
, 2004 The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

Vertical movements along the northwestern side of Messina straits, in the 1967-1970 period
Annals of Geophysics, 1982 The results of a comparison of the spirit levelling data made by I.G.M. in 1967<br />and in 1970, are presented. An analysis of these data shows that the altitude<br />variations of bench marks in the considered triennial period seem to ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]
, 2003 [1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.
