-
(2001)A new, simple, and easily reproducible experiment was designed to simulate the production, accumulation, and transport of melt within rock. The transport was found to be of the self-organized critical type. The emergence ...
-
(2000)New experimental developments for in situ X-ray absorption fine structure spectroscopy (XAFS) studies of hydrothermal systems are described. Improvements in materials of construction and the design of spectroscopic cells ...
-
(2003)The investigation of flow and transport parameters in fractured porous material is difficult due to the high permeability contrast between the fracture networks and the porous material, and due to the question of the scale ...
-
(2003)Yttrium arsenate Y[AsO4], chernovite, is a rare mineral discovered in 1966 and named in honor of A.A. Chernov, a prominent researcher of geology and mineral resources of the European northern region of Russia. He organized ...
-
(2004)Pistillate heads of Anadyticarpa altingiosimila gen. et sp. nov. from the Late Albian-Early Cenomanian of northeastern Russia are assigned to the Hamamelidaceae (Altingioideae) on the basis of their microstructure. The ...
-
(1989)In this article, we discuss new finds of granite and granite-gneiss in the Kurile Islands, both as fragments in beach deposits and as inclusions in volcanic rocks. Although an ice-rafted origin for some fragments is ...
-
(2001)The Timan-Pechora Basin, located west of the Ural Mountains in northern Russia, is a prolific oil province covering 300,000 km2. The basin, which has been efficiently explored, is predominantly oil prone, but significant ...
-
(2004)Seven new species of gall midges belonging to the genera Strobliella, Campylomyza, Neurolyga, Diadocidia , and Camptomyia are described from the Eocene Rovno amber.
-
(2003)Intercalated Na-rich montmorillonite-methane hydrate was synthesized for the first time. The upper limit of stability for the intercalate in pressure and temperature is parallel to that of methane hydrate but at temperatures ...
-
(1988)Our petrologic and geochemical study of the Archean Goran group in the southwestern Pamirs has revealed the wide extent of cordierite rocks formed after magnesite. Geologic and petrographic criteria clearly indicate that ...
-
NEW GENUS OF HETEROSPOROUS FERNS OF THE ORDER HEROLEANDRALES FROM THE LOWER CRETACEOUS OF KAZAKHSTAN (2001)As a result of a study of spore-bearing structures, a new genus, Vachramelia, is established for a fern from the Lower Cretaceous of Kazakhstan previously described as Adiantites prigorovskii Vachr. (Vachrameev, 1952). The ...
-
(1987)The basalts investigated were penetrated in drillholes near the villages of Nizhniy Mamon and Podkolodnovka as three flows with an overall thickness of 3 to 57 m. An earlier study of mineral and chemical compositions of ...
-
(1989)Our work gave new paleontologic and radiometric data on the age of the sedimentary, volcanogenic-sedimentary and igneous rocks in the structurally most complex northern part of Bering Island, which supplement existing ...
-
(1988)The high-pressure rock association in one area of Sakhalin is described. Within the area studied, the high-pressure association forms a sublatitudinally oriented zone, 300 to 500 m wide and composed mainly of alternating ...
-
(1998)The first finding of coesite in the garnet-mica schist of the Kulet site of the Kokchetav Massif is described. This fact indicates that the upper eclogite-bearing unit of the Kokchetav Massif was metamorphosed at pressures ...
-
(2003)The course of the nasolacrimal duct, interdental plate morphology, and most details of tooth and denticle morphology have not previously been described in non-archosauriform reptilkes. Here I describe these details in the ...
-
(1990)Deep seismic sounding with a total length of more than 8000 km was performed on 15 traverses through the Urals between 1962 and 1988. In addition, areal investigations have been performed in the middle and southern Urals. ...
-
(2002)New insect taxa from the Ufimian of Cherdyn' District, Perm Region, Visherifera camura gen. et sp. nov. (Grylloblattida: Visheriferidae fam. nov.), Misthodotes visherensis sp. nov. (Ephemeroptera), and Idelopsocus incommendatus ...
-
(2004)Orthorhombic edingtonite has been found coexisting with tetragonal edingtonite in a specimen from Ice River, British Columbia, Canada. We report data on the composition and crystal structure of the orthorhombic sample. ...
