(2002)We observe a 1.3 kg C/net GJ variation of carbon emissions due to inertinite abundance in some commercially available bituminous coal. An additional 0.9 kg C/net GJ variation of carbon emissions is expected due to the ...

PROXIMAL STRUCTURE AND DEVELOPMENT IN THE ORDOVICIAN GRAPTOLITE PARISOGRAPTUS CHEN AND ZHANG, 1996 (2003)The proximal development of Parisograptus Chen and Zhang is described from three-dimensionally preserved specimens. The unique development features an origin of proximal thecae like a string of pearls vertically upon each ...
-
(2003)In a previous study, we described proximity effects on surfaces of the semiconducting minerals galena and pyrite, whereby a chemical reaction at one surface site modifies the reactivity of a remote surface site several ...

(PANGAEA, 2016-02-23)Biogeochemical measurements in sediment cores collected with the submersible JAGO (pusch cores) and a TV-MUC in the Black Sea during MSM15/1, Northwest Crimea (HYPOX Project), at water depths between 152-156 m. A series ...
-
(2001)Basement structures, to which trishear fault-propagation models have most successfully been applied, are commonly three-dimensional folds formed at the tip-line of a fault. We present here a 'pseudo-3D' trishear model in ...
-
(2003)Liesegang bands with apparent offset along fractures are common in some calcisiltite beds. Thin sections show, however, that primary laminations are not offset along the fractures. Following the development of fracture ...
-
(2002)A new genus, Pseudorhabdomeson, with its type species, Ps. polygonium sp. nov., from the Kasimovian of the Russian Platform is described. Its axial zooecium has a distinctive form of a prismatic tube with a polygonal cross ...
-
(2000)Pseudosinhalite, Mg2Al3[O|OH|(BO4)2] and chondrodite, Mg5[(F,OH)2|(SiO4)2] are shown to be isostructural. Compositional and crystallographic relationships between members of the forsterite-clinohumite polysomatic series ...
-
(1998)After its initial synthesis as the new compound Mg2Al3B2O9(OH) (Daniels et al. 1997) pseudosinhalite has now been discovered as a new mineral. It occurs, together with hydrotalcite, as a replacement product of sinhalite, ...
-
(2002)The Cenozoic intracontinental Teletsk basin in the Central Asian Altai Mountains is composed of a complexly structured northern and a more simple southern sub-basin. These sub-basins formed in two distinct kinematic stages ...
-
(2002)Combined structural, compositional and osmium-isotope data on selected Pt–Fe nuggets from economically important placer deposits closely linked to clinopyroxenite–dunite massifs of the Siberian Platform (Kondyor, Inagli, ...
-
(2003)A specific assemblage of precious-metal minerals including majakite, Pb stannopalladinite, Pt-Pd tetraauricupride, plumbopalladinite, Sn plumbopalladinite, polarite, tetraferroplatinum, kuestelite, and electrum is described ...
-
(Минералогический музей им. А.Е. Ферсмана РАН (Москва), 2014)Для понимания условий образования уникальной оловоносной Cu-Fe формации Норильских Cu-Ni месторождений изучены продукты кристаллизации расплавов системы Cu-Fe-S с примесями платины, палладия и олова (1 мас.%). В фазовых ...
-
(2004)The Pt-Re-Os isotopic and elemental systematics of 13 group IIAB and 23 group IIIAB iron meteorites are examined. As has been noted previously for iron meteorite groups and experimental systems, solid metal-liquid metal ...

Pt–Re–Os and Sm–Nd isotope and HSE and REE systematics of the 2.7 Ga Belingwe and Abitibi komatiites (2009)High-precision Pt–Re–Os and Sm–Nd isotope and highly siderophile element (HSE) and rare earth element (REE) abundance data are reported for two 2.7 b.y. old komatiite lava flows, Tony's flow (TN) from the Belingwe greenstone ...

(2003)The endogenic activation of the Russian Platform governed by pulsating mantle processes of different degrees of intensity along the lateral direction were accompanied by block movements of the Earth's crust and magmatism.
