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

, 2014 The δ13Corg values of Phanerozoic black shales average −27‰, whereas those of modern marine organic matter average −20‰. The black shale isotopic values mimic those of continental organic matter, yet their organic geochemical properties mandate that they

Drivers of glacially induced fault reactivation in the Baltic Sea sector of the Tornquist Fan
Boreas, EarlyView.We analyse the effect of Quaternary glaciations on the complex tectonic pattern of the Baltic Sea sector of the Tornquist Fan. Using 2D marine reflection seismic data we determine the strike and dip angles of more than 40 potential glacially reactivated faults and calculated the Coulomb failure stress changes (ΔCFS) over the past 200 000 years.

A mineral reconnaissance survey of the Abington-Biggar-Moffat-area, south-central Scotland [PDF]
, 1979 Panned heavy mineral concentrates, mostly obtained from stream sediments, were collected from 195 sites in the Abington-Biggar-Moffat area. The project area, which lies immediately east of the formerly important mining district of Wanlockhead ...

, 2014 Chemical and isotopic signatures for black shales serve as potential proxies for reconstruction of paleoenvironmental conditions. Here we bring Rock‐Eval, major and trace element and Re‐Os isotopic data together to examine the environmental record at the
