The Benthic Boundary Layer: geochemical and oceanographic data from the GEOSTAR-2 observatory
geochemical data oceanographic data Benthic Boundary Layer
2015/9/7
Geochemical and oceanographic data, acquired throughout 6 months by the GEOSTAR-2 benthic observatory in southern Tyrrhenian Sea, evidenced ocean-lithosphere interactions in the 1900-m deep Benthic Bo...
Active faulting and transpression tectonics along the plate boundary in North Africa
Tell Atlas North Africa Plate boundary Transpression
2015/8/26
We present a synthesis of the active tectonics of the northern Atlas Mountains, and suggest a kinematic model of transpression and block rotation that illustrates the mechanics of this section of the ...
Chitinozoans in the Wenlock-Ludlow boundary beds of the East Baltic
chitinozoans correlation Wenlock Ludlow Silurian East Baltic
2009/10/21
The distribution of chitinozoans in the Wenlock–Ludlow boundary beds was studied in five drill core sections of the East Baltic. It was established that most of the typical Wenlock chitinozoan sp...
Conodont biostratigraphy in the Middle-Upper Ordovician boundary beds of Estonia
conodonts correlation biostratigraphy Ordovician Estonia
2009/10/21
Conodonts of the uppermost Uhaku, the Kukruse, and the lower Haljala stages (uppermost Darriwilian and lower Sandbian) of Estonia are discussed. The distribution of conodonts within the Pygodus serra,...
Carboniferous-Permian Boundary in Kansas,Midcontinent,U.S.A.
Carboniferous-Permian Boundary Kansas
2009/10/20
The placement of the Carboniferous (Pennsylvanian)-Permian boundary in Kansas has been debated since the rocks of this age were first described and named. With the ratification of the Global Stratotyp...
New genus of chondrichthyans from the Silurian-Devonian boundary deposits of Tuva (Russia)
Chondrichthyans Elegestolepids Silurian Devonian Tuva
2009/10/20
The scales of T.schultzei display significant morphological variation and are characterized by a very fine, comparatively wide and flat crown with longitudinal ribs and a small and short neck. The gro...
The Problem of the Core-Cover Boundary of the Menderes Massif and an Emplacement Mechanism for Regionally Extensive Gneissic Granites, Western Anatolia (Turkey)
gneissic granites syntectonic granites Menderes Massif western Anatolia
2009/7/8
In previous studies, the stratigraphy of the Menderes Massif was divided into a Precambrian core and Mesozoic cover associations, the core consisting of gneissic granites and high-grade schists and th...

Heat capacity and thermodynamic properties for coesite and jadeite, reexamination of the quartz-coesite equilibrium boundary
Heat capacity thermodynamic properties quartz-coesite equilibrium boundary
2012/3/31
The heat capacities of synthetic coesite and jadeite were measured between about 15 and 850 K by adiabatic and differential scanning calorimetry. The experimental data were smoothed and estimates were...
