FOSSIL 26AL AND 53MN IN THE ASUKA 881394 EUCRITE: EVIDENCE OF THE EARLIEST CRUST ON ASTEROID 4 VESTA (2003)Asuka 881394 is a unique magnesian eucrite with pyroxenes that are Mg-rich like those of cumulate eucrites, but with a granulitic texture unlike the textures of cumulate eucrites. Plagioclase compositions are ~An98, and ...
-
(2003)The study of fossil bacteria suggests that the character of sedimentation in ancient epicontinental basins strongly depended on the abundance of microorganisms. At present, the appearance of eukaryotes, coelomates, etc., ...

(2002)Key Words atmospheric CO 2 , stable carbon isotopes, leaf fossils, stomata s Abstract Developments in plant physiology since the 1980s have led to the real-ization that fossil plants archive both the isotopic composition ...
-
(2002)Micro-Raman spectroscopic analysis allows us to estimate the internal pressure of small fluid inclusions. We applied this method to CO2-dominated fluid inclusions in mantle-derived xenoliths. The pressures estimated from ...
-
(1998)Fossil roots Radicites sukhonensis sp. nov. and R. erraticus sp. nov are described from the Upper Tatarian Substage in the basin of Sukhona and Malaya Severnaya Dvina rivers. Fossil roots are assigned to five distinct ...
-
(2001)The suborder Paratrichoptera (Mecoptera) is discarded as polyphyletic. The family Choristopsychidae Mart. is synonymized under Permochoristidae Till. The generic composition of the family Mesopsychidae Till. is revised. ...

(2002)Fossil wood of the Engelhardioideae was found in Russia for the first time. A new species Engelhardioxylon mameticum sp. nov., from the Oligocene of the Esgichninvayam River basin (Mametchinskii Peninsula, Kamchatka) ...
-
(2004)A new form genus, Pseudotsugoxylon, is designated to include fossil woods with anatomical characters typical of extant Pseudotsuga. The material came from the Pliocene of the Pavlovka lignite field (southern Primorskii ...
-
(2003)Two new species, Laricioxylon priamnrensis and Populoxylon priaimtrensis, are described from the upper Miocene of the Erkovetskii brown coal field (Amur River Region) on the basis of wood anatomy. The former combines ...
-
(1989)Cyclic layering is a common feature of the ultramafic zone of layered intrusions and is usually attributed to the entry of new pulses of dense magma into the chamber. Since the crystallization of olivine and bronzite lowers ...
-
(2003)In the southeast of Western Siberia within the zone of birch and pine forests in the Ob'-Tom' interfluve area, four new pollen diagrams from sites in different landforms (interfluve, terraces, floodplain, and ancient ...
-
(2004)Fractal analysis has been performed on ultra-low-frequency (ULF) geomagnetic field data observed at the Izu peninsula. The first attempt of using fractal analysis for ULF geomagnetic field data during the large Guam and ...
-
(1996)A model for an earthquake simulation is proposed with the use of a fractal approach. Multiple generation and coalescence of shear faults in stochastic brittle media (modelled as a 2d lattice) are considered to be a source ...
-
(1988)Investigation of areas where ferromanganese nodules occur on the sea floor identifies a characteristic property of their structure: the nodules are not uniformly distributed, but form regular clusters and sparse areas. For ...
-
(2001)In the past, a great deal of research has been conducted to determine the fractal properties which quantify the sinuosity of individual streams and the branching configuration of stream channel networks in watersheds. Much ...

(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2016)It is shown in the paper that the system of equations of solid mechanics, which has a mixed type, demonstrate the most common features of evolution of nonlinear dynamic systems. Previous investigations of seismic process ...
