The new scheme of East European platform basement's zonation is discussed. The regularities of geological complexes location allow to separate four geoblocks/ Geoblocks, which are located symmetrically, have similar structure, composition and size.

The maps of distribution of gold concentration and its elements-indicators on a surface were constructed for the site of gold mineralization Ponpel-Shor (Polar Ural). The application of the geostatistical Module ArcGIS allows to study anisotropic distribution of elements and confirms the assumption that the gold mineralization was formed in 2 stages.

Silver is found as by-product component in such countries as Costa-Rica, Salvador, Honduras, Guatemala and Nicaragua in polymetallic, gold and directly in gold-silver deposits. Small gold-silver deposits are being prospected in Salvador; precious metals intensive are being prospected in Costa-Rica, but their producing is presented less than 1% of Gross Domestic Product, in Guatemala producing of silver has increased by 7 times from 2005 to 2007 years, but in Nicaragua increased by 2 orders. even thought the mining industry in Central America has experienced minimal growth from 2005, it still faces uncertainty due to World Financial Crisis.

The new data ascertaining amberisation process and the amber s transfer mechanism into the sedimentation basin are considered.

In Velikij Ustug region stones with some specific features are known. According to ancient legends and chronicles these stones presumably are of meteoritic origin. The detailed mineralogo-petrographical, petrophysical and mineragraphycal analyses of one of such stones showed, that most probably it has Earth origin.

Early Vendian volcanic volynskaya series in the South-Western part of the East-European platform contains two types of rock's paragenesa which differ by petrochemical trends. One of these types corresponds to tholeitic, other - to kimberlitic trends. Guestions of possible connections of Cu and Au mineralization with different paragenesa boundaries are discussed.

Questions of research and mapping of carbonaceous deposits, based on petrophysical, petrochemical and geological methods, are discussed.

Modern trends in the development of oil and gas World complex are characterized: increase of exploration volumes on continental shelf, wide-scale using computer technology for increase reserves on already known fields, using of horizontal drilling for increase oil recovery, sharp growing liquefied natural gas production.
