... conformity, by the Muzuma Formation, dominated by calc-silicate rocks with minor pure quartzites, marbles, and mica schists. Again, the thickness of this formation is unknown. These two formations were tentatively correlated with the similar sequence of rock types in the Kafue-Lusaka area (Mulola to Cheta...

... of the section, because a succession of ammonite zones from outcrop 2 is taken as a base. The Neocomian key section consists of four basic units. At the bottom lies a basal member of gravelly sandstones referred to the upper part of the Fedorovo Formation. The member discordantly lies on rocks of the Upper...

... studies. The new magnetozone embraces the Volgian–Ryazanian boundary (Chetaites chetae/C. sibiricus zonal boundary). It was also found that the former magnetozone M17r at Nordvik, which includes the C. sibiricus/Hectoroceras kochi zonal boundary should correspond to magnetozone M16r. Using...

The study shows that high concentrations of isotopically light organic carbon in the first diasterene geochemical subhorizon were caused by high...

... ); they are dominated by terrigenous rocks of marine and continental geneses, which are of very different lithologic compositions and belong to the upper part of the regional Bazhenovo Horizon (Resolution, 2004 ).

In these areas, the Archaean grani tes are unconformably overlain by the quartzites of Bairenkonda (Tirumala and Satyavedu...
