-
(2004)The qualitative and quantitative analysis of the holomorphic folding morphology in the central segment of the South Tien Shan revealed its heterogeneity in the Paleozoic rock sequences. Against the background of the gradual ...
-
(2002)Neocassandra mica Daniltshenko, 1968 from the Late Paleocene of Turkmenistan is revised and assigned to the order Aulopiformes. However, it substantially differs from all members of the order in the following characters: ...
-
(2001)The systematic position of a peculiar group of Angaran gymnosperms usually treated as "cordaites" is discussed. The systematics of these plants related to coniferophytes remains uncertain because of their extreme peculiarity. ...
-
(2003)The morphology and systematic position of Sphenophyllum biarmicum Zalessky are discussed. "Gangamopteris" fimbriata Zalessky, "G." tenuinervis Zalessky, and Sphenophyllum comiense Tschirkova are considered to be synonyms ...
-
(1999)High-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) peak broadening (Scherer) analysis were used to study coarsening and morphology development of nanocrystals. Experimental work used ...
-
(2003)Eight morphological types of the initial chamber (cephalis) of Late Cretaceous radiolarians of the order Nassellaria are described; seven of them, i.e., Perseus, Napora, Arcanicapsa, Cornutella, Theocoronium, Sciadiocapsa, ...
-
(2001)In pelitic schists composed mainly of quartz and albite grains, the morphology of intergranular pores, which were filled with water, was studied by transmission electron microscopy (TEM). Although some pores are defined ...
-
(1988)We made mass determinations of the morphology and the particle size of non-recoverable gold from weathered mantle developed in Yakutia, the Krasnoyarsk kray and the Urals on gold-sulfide-quartz deposits with finely divided ...
-
(2004)On the basis of a comprehensive analysis of the morphology of the genus Rhombotrypella, its astogeny is described for the first time. The taxonomic composition of this genus is revised to comprise 45 species. The lifespan ...
-
(2004)Morphology and growth mechanisms of diamond crystals in polycrystalline films synthesized from hydrocarbon gas have been studied under an electron microscope using secondary electron images. It was found that at the earlier ...
-
(1998)This paper describes morphometric measurements made in Lake Karymskoe in connection with the underwater eruption of January 1996. Echo sounding was carried out in April-September of 1996. Bathymetric maps were plotted for ...
-
(1988)This article discusses the shape characteristics of iron-manganese nodules and their dependence on the chemical composition and growth rate of the nodules. A sample of length of three axes for 609 nodules from the ...
-
(2003)Knowledge of mineral aggregate morphologies is of importance to analyze characteristic differences in rock-forming features. For quantifying these differences, the fractal geometry of quartz aggregate cuts digitized from ...
-
(1999)The new maps of Quaternary and recent tectonic movements were compiled with the use of new geologiegéomorphologie and geodetic data.
-
(1997)The Holocene deformations of the central part of the Tien Shan mountain range in Kazakstan were studied in the field and by photointerpretation in order to reconstruct the geometry, kinematics and rate of faulting. The ...
-
(1990)The mountains of north-eastern Inner Asia comprise the Mongolia-Siberian orogenic belt which has a complex structure. The southern flank of the belt consists of a chain of large domal uplifts. The Baikal rift zone is located ...
-
(2001)The morphological variability of Stenocranius gregalis Pallas from the Paleolithic site Denisova Cave (Altai) is examined. The variability of the unpaired anterior loop of M] is discussed. Seven morphological types are ...
-
(1987)The main results are presented of an analysis of the structures of the seismograms. Structure is understood to mean the set of the following factors characteristic of the wave field: number of regular waves, their relative ...
