Tab. 3: Fission track ages
Samples with a 2 value >5 pass the 2 test at the 95 % confidence level. Central ages (± 1-? error estimates) are reported (GALBRAITH & LASLETT 1993), which are the same... -
Age determination of microbial carbonates deposited during the Holocene in th...
The data refer to the geochemical and isotopic characterization of microbial carbonate in the shallow platform of the South Atlantic Ocean, Espírito Santo - Brazil. The... -
Age determination of beachrocks and hybrid carbonates deposited during the Ho...
The data refer to the geochemical and isotopic characterization of sandstones, with carbonate cementation (beach rocks), and hybrid carbonates, formed by algal mats, in the... -
U-Pb, trace element, and Hf isotope analysis for Macquarie Island detrital zi...
Oceanic zircon trace element and Hf-isotope geochemistry offers a means to assess the magmatic evolution of a dying spreading ridge and provides an independent evaluation of the... -
Tab. 1: Rb-Sr data on metasediments in the Shackleton Range
Summary: The stratigraphy of the Shackleton Range established by Stephenson (1966) and Clarkson (1972) was revised by results of the German Expedition GEISHA 1987/88. The... -
Tab. 2: U-Pb ion-microprobe ages from Taymyr peninsula
We present the initial results of a U-Th-Pb zircon ion-microprobe investigation on samples from the Central Belt of Taimyr, in order to constrain its tectono-magmatic evolution.... -
Tab. 1: Ar40/Ar39 results from Kuyul terrane, northeastern Russia
The Kamchatka Peninsula of northeastern Russia is located along the northwestern margin of the Bering Sea and consists of zones of complexly deformed accreted terranes. Along... -

Tab. 1: Zircon isotopic data and rock ages from the Antarctic Peninsula
Morphological and U-Pb isotope studies on sedimentary zircons reflect the orogenic evolution of their former host rocks. The orogenic history of detrital zircons from the... -
Tab.1: Representative bulk-rock and trace element chemistry
High-pressure/low-temperature metabasites occupy a definite geological position within the structure of the Polar Urals and have a very important bearing on the understanding of... -
Tab.1: Composition of salt crusts and host rocks
Gypsum and calcite crusts were found on many outcrops of the metamorphic basement and on moraines in Dronning Maud Land. For the first time the copper mineral connellite was... -
Tab. 1: Trace-element concentrations in ore samples collected from mercury mi...
A belt of small but numerous mercury deposits extends for about 500 km in the Kuskokwim River region of southwestern Alaska. The southwestern Alaska mercury belt is part of... -
