This document gives guidelines for taking duplicate measurements by in-situ analytical instruments, or collecting duplicate samples for analysis in the mobile field laboratory, to assess random errors originating from sampling and analytical procedures, and to estimate the uncertainty of measurements. Since, NORISC is dealing with the assessment of contamination of small-size areas within cities, and relies mainly on in-situ analytical methods, a cost-effective technique, using robust analysis of variance for the estimation of necessary quality control parameters, and measurement uncertainty, is explained with examples <...>

Geochemical data are generally derived from government and industry geochemical surveys that cover areas at various spatial resolutions. These survey data are difficult to assemble and integrate due to their heterogeneous mixture of media, size fractions, methods of digestion and analytical instrumentation. These assembled sets of data often contain thousands of observations with as many as 50 or more elements.

Many Earth science departments today recruit significant numbers of environmental geoscience students alongside mainstream geology or Earth science students. This student-led change in academic emphasis suggests that a successor to Chemical Fundamentals of Geology will meet the needs of students better if it covers the chemical foundations of environmental Earth science as well as geology. The shift in the emphasis of this new edition is reflected in its expanded title. <...>

В работе рассматривается проблема геохимической миграции атомов вещества под воздействием теплового и гравитационного нолей планеты. Предложено математическое определение условий концентрации веществ, полученное на основе анализа соотношений физики сплошных сред и теории необратимых процессов. Предлагаемая формула позволяет в первом приближении определять химический состав глубинных зон Земли.

Работа предназначается для широкого круга читателей — геологов, геофизиков и геохимиков.

Minerals are highly significant components of coal from both academic and practical perspectives. Minerals may react when the coal is burned, either forming an ash residue, or, in many cases, releasing volatile components, or as they need to be removed as slag from the blast furnace during metallurgical processing.
