Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
My purpose in writing this manual is to provide a pocket-size presentation of field procedures without the bulk and cost of a comprehensive textbook.
he first part, Tools of the Trade, covers the Brunton compass and Jacob's staff, the Silva compass, and the plane table and alidade-along with principles of map direction and strike and dip.
Also, I have included a section on uses of the stereographic net for those who lack hardware and software necessary for the manipulation of field measurements.
The National Uranium Resource Evaluation (NURE) Program was established in 1973 by the U. S. Atomic Energy Commission (AEC) which later became the U. S. Energy Research and Development Administration (EKDA) and is now funded by the United States Department of Energy (DOE). The principal objectives of the NURE Program are as follows: 1. To complete a comprehensive assessment of the uranium reserves of the United States as rapidly as possible, 2. To identify areas favorable for uranium resources, and 3. To develop new and improved technologies. <...>

The International Council for Applied Mineralogy congress (ICAM) is the most important regular gathering of applied mineralogists. The ICAM 2011, to be held at the Radisson BLU Royal Garden Hotel in Trondheim, Norway, on 1-5 August, is our 10th meeting. It has been 30 years since the inaugural meeting in Johannesburg, South Africa in 1981 and this decenary event perhaps heralds a new era for Applied Mineralogy as we tackle a whole new set of challenges facing our world today.
Having been a part of marine biota, the coleoid cephalopods played and recently still play an important role in nekton assemblages. As it has several times been mentioned, coleoid cephalopods belong to rarer fossils (except belemnites), thus the reconstruction of their evolution, paleobiology and ecology suggests the combined actualistic - neontologic and palaeontologic approach. This completely opens a new view into a fascinating and amazing world of extinct and present coleoids, their habitat, relationships and evolution.<...>

The global distribution of continents and oceans demonstrates a double asynunetry of north-south and east-west. The geoid height has distribution panem of first-and second-order anonlalies. The global active tectonics can be classified into three first-order tectonic systems: the circum-Pacific tectonic system, the mid-occan ridge tectonic system, and the continental tectonic system ofthe north h.:rnispbere. They indicate the asymmetry of north-south and east-west as well. The mechanism of the general westward motion of the global plates is presumably associated with the angular velocity differences bdween crust, mantle and core. 11Iese tectonic features ofa global scale stem probably from the heterogeneities of the inner stmctures ldl by the early evolution of the Earth and from the combined effects offorces with mUltiple sources. <...>
