The Mediterranean Sea lies between Europe, Asia and Africa in an area famous for its ancient civilizations and cultural developments. It was an area where marine navigation was developed and where many trade routes intersected. The publication of one of the first monographs on marine geology and geography by Marsilli in 1725 suggests that the Mediterranean Sea was the cradle of marine geology.

It is known that methane (and, in smaller amounts, higher hydrocarbons) is liberated during the coalification process. The amounts of methane developed vary in the different stages of coalification. Calculations on the basis of ultimate analyses of coals of different rank done by Mott (1943), Patteisky(1952, 1964) and Jüntgen and Karweil (1966) lead to the conclusion that greater amounts of methane start to be developed when the stage of bituminous coals with about 30% of volatile matter (dry and ash-free) is reached, whereas the gas developed from lignite and less metamorphosed bituminous coals is mainly carbon dioxide.

This book is about geochemical data and how they can be used to obtain information about geological processes. Conventionally geochemical data are subdivided into four main categories: the major elements, trace elements, radiogenic isotopes and stable isotopes (see Table 1.1 ). These four types of geochemical data each form the subject of a chapter of this book. Each chapter shows how the particular form of geochemical data can be used and how it provides clues to the origin of the suite of rocks in question. Different methods of data presentation are discussed and their relative merits evaluated. <...>

This guidebook is dedicated to ultramafic-mafic intrusions, volcanic rocks and the world-class PGE-Cu-Ni sulfide deposits of the Noril’sk Province, Polar Siberia. The characteristics of geology, mineralogy and geochemistry of volcanic rocks and ore-bearing ultramafic-mafic intrusions are briefly outlined. The proposed excursion stops include inspection of the different volcanic and intrusive rocks, associated PGE-Cu-Ni sulfide ores from drill cores and bedrock outcrops. In addition, an open pit Medvezhy Ruchei and two mines (Oktyabrsky and Taimyrsky) collectively provide an overview of the Noril’sk-type intrusions and associated disseminated and massive PGE-Cu-Ni sulfide ores.

Обогащенные PGE–(REE–Ti) элементами включения микрометрового размера, минеральные ассоциации, вариации состава и потенциальный источник минералов платиновой группы в россыпной зоне Сисим, Восточные Саяны, Россия.

We report the results of a mineralogical investigation of placer samples from the upper reaches of the Sisim watershed, near Krasnoyarsk, in Eastern Sayans, Russia. The placer grains are predominantly Os–Ir–(Ru) alloys (80%) that host various inclusions (i.e., platinum-group elements (PGE)-rich monosulfide, PGE-rich pentlandite, Ni–Fe–(As)-rich laurite, etc.) and subordinate amounts of Pt–Fe alloys.

The purpose of this book is to provide the reader with guidance on the development and implementation of cost-effective and defensible environmental sampling programs that are designed to collect data needed to
• Defi ne the nature and extent of contamination

• Calculate baseline human health and ecological risk
• Identify contaminant migration pathways
• Predict rates of contaminant migration
• Evaluate the viability of potential remedial alternatives
• Support treatability testing
• Assess the effectiveness of a remedial alternative during implementation
• Determine if remedial action objectives have been met
• Dispose of waste material properly

Формирование базальтовых комплексов океанических островов (OIB=Ocean Island Basalts) обычно рассматривается в связи с деятельностью мантийных плюмов, проплавляющих океанскую литосферу на разных стадиях ее развития.

The purpose of this research has been to determine the origin of the San Vicente zinc-lead deposit based on textural, mineralogical and geochemical studies of the sulfide ores and carbonate host rock. The relatively simple and uncomplicated mineralogy of the ores and host rock permits the application of standard petrographic techniques as well as specialized methods such as cathodoluminescence, electron microprobe analysis, and detailed sulfur isotope geochemistry. <...>
