Mechanism of biosphere homeostasis as a cause of great glaciations, mass extinction, and periodicity of sedimentation and ore accumulation

Malinovsky Y.M.

Abstract

Self-oscillatory mechanism of biosphere homeostasis is substantiated by periodic alteration of water stratification by the salinity of the warm ocean to that by the temperature of the cold ocean and vice versa. These passes originate rhythmic cascades in inter-ocean currents and lead to global changes.

Geochemical prospecting of endogenic gold deposits

Trofimov N.N., Rychkov A.I.

Abstract

Rational complex of prospecting methods for endogenic gold deposits which are of different scale and significance is studied and distinguished. Prospecting aims and tasks at the geological and explorations legs as far as methods of geochemical investigations are offered. Special attention is pied to anomalies finding out and appreciation of its ore formation and economic value.

Relief of island Sri Lanka (south-western part) and placers

Kolosova G.N., Trofimov N.N., Gamini Soisa -., Dubrovskaya E.M.

Abstract

On the explored territory 5 genetic types of the relief are distinguished as well as related to them gem sands. These gem sands had been formed in the Kalu-Ganga river valley within the junction zone of the low accumulative plain-depression and low hill and low mountain ridge relief made up by the productive Proterozoic thick layers.

Geology and secondary dissemination aureoles of the north part of Mikheevskoe copper-porphyric deposit

Kotelnikov A.E., Diakonov V.V.

Abstract

The article is devoted to discussion of mineral composition of ore and mineral sequence. We learned secondary dissemination aureoles of Mikheevskoe deposit. And contrast secondary aureoles of Cu, Zn, Pb, Ag, I, Mo, Fe were traced above the north part of deposit. It's spatial position is typical for copper-porphyric deposits.

Geological position and composition of Au-Ag ores of Central Chukotka

Lorentz D.A., Sergievski A.P.

Abstract

The Upper Yablon and Penzhina-Anadyr metallogenic zones lie within the Central sector of the Okhotsk-Chukchi volcanogenic belt. These zones are made of Cretaceous volcanic covers and bodies of comagmatic subvolcanic and extrusive varieties. Volcano-tectonic structures define positions of ore clusters (trends) bearing Au-Ag mineralization. Argentiferous sulfosalts and fahlerz are most typical of ore-bearing veins and veinlet zones of the Upper Yablon zone, whereas acanthite prevails among the ore minerals in the Penzhina-Anadyr zone.

Oil and gas potential of area of water Northern Caspian

Kiryukhin L.G., Khakimov M.Y.

Abstract

At the beginning of current century the new large North-Caspian oil-gas bearing area was opened in Russian sector Caspian. Pools oils and gas are contained in Deposits of Middle and Upper Jurassic, Lower Cretaceous and Paleogene. The storey of oil and gas Potential - 2700 m. Based on discovered Fields new large region oil and Gas Production is formed in Russia.

Stable associations of magmatic rocks (problems of isolation and classification)

Sveshnikov K.I.

Abstract

Study and systematization of magmatic rocks combinations (volcanic series, magmatic complexes, formations, associations) is one of the paramount tasks in petrology. The decision of this task opens opportunities for detection of some new petrological regularities. The distinguishing of magmatic associations which steadily recur in space (elementary or stable associations) allowed to show the existing in the Nature some petrological groups of such associations. These groups differ between themselves by petrochemical trends.

Litological, petrographic and mineralogical peculiarities of series containing Au-ore deposit Ponpelshor (Polar Ural)

Zhelezova E., Georgievski A.F., Karelina E.V.

Abstract

It is very important now to search and study new Au-bearing deposits in Russia as a whole and in Polar Ural in particular. Series, containing one of such deposits - Ponpelshor, consist of metamorphic schists. The previous nature of schists is discussed.

About the possibility of using reflected waves for detection of karst cavities

Makarovsky O.V.

Abstract

Accidents with buildings in Moscow above karst cavities created caused nessesity to detect them with the help of geophysics. The dynamic and kinematic anomalies were simulated and surveyed with the method of photoplastic on the interval of reflection wave's T-D curves. These anomalies were situated in the shadow zone above the karst cavities and created by refraction (enveloping) and diffraction. Wave's T-D curves were built and the complying composite of coupling of diameter cavities and the depth of it's orientation with the time delay of T-D curves and changing of wave's amplitude in the shadow zone. The compositing of this coupling is that if the cavities diameter enlarges, the effect of refraction increases, but the effect of diffraction (enveloping) decreases.
