-
(1997)The composition of mollusks from the hole near the town of Anan'ev (Ukraine) has been analyzed. The green sand and clay beds, which in Moldavia and Western Ukraine (Podolia) are referred to as the Podolian Formation, do ...
-
(2004)Relations between reflection and transmission responses of horizontally layered media were formulated by Claerbout in 1968 and by many others. In this paper we derive similar relations for 3-D inhomogeneous media. As the ...
-
(2003)The petrological properties, and O and Al-Mg isotopic compositions of two spinel-bearing chondrules from the Allende CV chondrite were investigated using scanning electron microscopy and secondary ion mass spectrometry. A ...
-
(2004)A large number of seismic records are discovered for the first time in the historical materials about Wudalianchi volcanic group eruption in 1720–1721, which provides us with abundant volcanic earthquake information. Based ...
-
(2002)The hypothesis that the parent stratigraphy of a coal seam, i.e. its lithotype and band distribution, can be used to estimate the input and output size distributions of broken coal for a fragmentation event(s) was tested ...
-
(2004)Jadeitite is a well known but rare rock type that is found only in a few places in the world. Jadeites are always found in the subduction and subsequent continental collision zone, associated frequently with blueschist ...
-
(1990)Work of recent years has convincingly shown that virtually all rift structures, whether continental or oceanic, expand in two directions simultaneously. Thus, the rift undergoes not only transverse extension (spreading), ...
-
(1990)An empirical relationship between compressional wave velocity (Vp) and radiogenic heat generation (A) is frequently used to estimate heat production distributions in the continental crust. Two data sets from Rybach and ...
-
(2006)Grain size- and crystallographic direction-dependence are among the fundamental characteristics of crystal solubility. However, such important material properties are routinely ignored and solubility is often conveniently ...
-
(1990)In this paper we describe the determination of the temperature field and estimation of surface and plutonic heat flows and of the contribution of radiogenic heating to the total heat flux in a particular region (Kura ...
-
(2003)We investigated the relationship between noble gas signatures and sample textures among glassy fragments. Glassy MORB fragments were classified based on their texture. By handpicking under a binocular, they were divided ...
-
RELATIONSHIP BETWEEN SURFACE STRUCTURE, GROWTH MECHANISM, AND TRACE ELEMENT INCORPORATION IN CALCITE (1995)Crystal growth and coprecipitation experiments demonstrate the manner in which surface structure and, in turn, crystal structure influence growth mechanism and trace element incorporation in calcite. Dominant {1014} faces ...
-
(1988)One of the main parameters describing the genetic features of ore deposition in the ocean and its intensity and history is the rate of growth of ferromanganese nodules (FMN). Despite much experimental work in recent decades, ...
-
(2002)The oxygen isotope composition of bone and tooth phosphate of 50 fox specimens and 30 reindeer specimens from various locations with different climatic and environmental conditions was measured. The existing relationship ...
-
(1990)It is not illogical that acoustic noise in the interior of the earth should be correlated with the moon- and sun-induced earth tides; but while some published data support this view, other investigators cast doubt on the ...
-
RELATIONSHIP OF THE SPECIFIC ENERGY OF COMMINUTION AND THE MECHANICAL STRENGTH OF MINERALS AND ROCKS (1988)Because the concept of comminution (atomization) energy E underlies the analyses of the physical properties of materials, the author investigated the relationship between the specific atomization energy E m (E m = E/M, ...
-
(1990)Vein deposits, the traditional source of gold, have been known for a very long time. In addition, however, disseminated ores of stratiform and other 'large-volume' ore deposits have recently become increasingly significant. ...
-
(1999)Noble gas isotopic abundances of ten lodranites (EET84302, FRO90011, Gibson, LEW86220, LEW88280, Lodran, MAC88177, QUE93148, Y74357, Y791491) and four acapulcoites (Acapulco, ALH81187, ALH81261, ALH84190), as well as major, ...
-
(1998)The integral stratigraphic scheme for the Lower Paleozoic (Lower Cambrian to Middle Ordovician) is considered on the basis of new finds of organic remains in the Kursai (small shally fossils), Karagaily (algae, trilobites, ...
-
(2001)In contrast to sedimentary sequences, the relationships between the stressed state of igneous rocks and the chemistry and physical properties of gases contained within them are not well known. Here, we attempt to fill this ...
