Публикация тезисов Всероссийской научной конференции «Геология, Геохимия и Геофизика на рубеже XX и XXI веков представляется важным для отечественного геологического сообщества. Совещание созвано в связи со знаменательной датой - 10-летия Российского фонда фундаментальных исследований. Десять лет - достаточный период времени, чтобы судить об эффективности новой формы организации и финансирования фундаментальных научных исследований. - в нашем случае - для наук о Земле. Вывод однозначен.

 Представление о круговороте химических элементов в земной коре, введенное и разрабатывавшееся в геохимии В.И,Вернадским, А.Е.Ферсманом, В.М.Гольдшмидтом, А.П.Виноградовым, является синтезом закономерностей поведения элементов в процессах образования и преобразования вещества земной коры. Основными целями такого синтеза являются:

Даны основные понятия общей геохимии, показано значение геохимических исследований при поисках и разведке нефти и газа. Рассмотрены преобразование органического вещества осадочных пород при литогенезе, геохимия нефтей и природных газов, геохимические методы (газовый, битумный и др.) поисков нефтяных и газовых месторождений, роль геохимических исследований при контроле за разработкой месторождений этих полезных ископаемых.
Для студентов вузов, обучающихся по специальности ’Теология нефти и газа”.

Cenozoic, mafic alkaline volcanic rocks throughout West Antarctica (WA) occupy diverse tectonic environments. On the Antarctic Peninsula (AP), late Miocene Pleistocene (7 to < 1 Ma) alkaline basaltic rocks were erupted < 1 to 45 million years after subduction ceased along the Pacific margin of the AP. In Marie Byrd Land (MBL), by contrast, alkaline basaltic volcanism has been semi-continuous from 25-30 Ma to the present, and occurs in the West Antarctic rift system. Together, these Antarctic tectono-magmatic associations are analogous to the Basin and Range, Sierran, and Coast Range batholith provinces.

The aim of this book is to summarize the current state of knowledge on the environmental geochemistry and resource potential of metallurgical slags. Hundreds of millions of tonnes of slag, a by-product of pyrometallurgical processing of ferrous and non-ferrous ores or recyclable materials, are generated annually worldwide. These slags are either landfilled, reprocessed, or repurposed.

Explosive volcanic eruptions eject large volumes of high surface area, metal-rich dust and ash into the atmosphere. In areas near major volcanic eruptions, humans often interact with these materials and may bioaccumulate heavy and toxic metals. To evaluate these interactions, we examine bronchoalveolar lavage samples (BAL) collected from people exposed to the paroxysmal 2001 Etna eruption.

This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits. Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience. Because of my orientation, the treatment given is perhaps more sedimentological than is usually found in books on ore deposits, but I hope that this proves to be an advantage. It will also be obvious that I have drawn heavily on the ideas and techniques of Robert Garrels.

The term “geochemistry” was first used by the German-Swiss chemist Christian Friedrich Schönbein* in 1838. You might guess, merely from the etymology of the word, that the field of geochemistry is somehow a marriage of the fields of geology and chemistry. That would be a good guess. But just how are chemistry and geology combined within geochemistry; what is the relationship between them? Perhaps the best explanation would be to state that in geochemistry, we use the tools of chemistry to solve geological problems; that is, we use chemistry to understand the Earth and how it works.
