The interpretation of connections between geophysical fields and paleovolcanic structure is presented in the article.

The analysis of mineral parageneses, ore textures and structures, stable isotopes in minerals provided a base for understanding of mineralization processes in two big metasomatic Pb-Zn deposits Sasa and Toranica located in the same structural-metallogenic zone of SMM.

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.

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.

The problems of structure geometrization of productive stratums of hydrocarbon deposits are considered. The methodic of the theoretic and empiric typization of elements based on this signs is developed.

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.

In this work аre presented data on the technical state of stone facing of the pedostal, characterization and description of the facing stone, that was previously considered te be Carrara marble.

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.
