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 <...>

The Manual was prepared as part of a programme of the International Atomic Energy Agency to publish instruction manuals on a wide range of practical topics. Its purpose is to assist in the establishment of an analytical laboratory able to perform all the basic chemical and instrumental analyses commonly used in conjunction with uranium exploration and mining and ore processing activities, including the development of hydrometallurgical processes.

An orogenic gold deposit is a structurally controlled gold occurrence formed during one of the major stages of an orogeny by orogenic fluids. Any rock type within a greenstone or schist belt, a metamorphosed supracrustal rock, dyke, or intrusion within or intrusion bounding such belt may host an orogenic gold deposit.

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.

В книге изложены основные свойства рентгеновского излучения и зависимости интенсивности линий этого спектра от условий возбуждения и химического состава излучателя. Достаточно подробно описана аппаратура для рентгеноспектрального анализа, способы анализа и подготовки пробы, наиболее распространенные в аналитической практике. На конкретных примерах показаны приемы статистической оценки рабочих характеристик методик анализа; даны рекомендации по организации контроля качества работы аналитических рентгеноспектральных лабораторий 

Книга предназначена для инженерно-технических работников рентгеноспектральных лабораторий, непосредственно занятых выполнением анализов, и может быть рекомендована для студентов, специализирующихся в области физических методов анализа вещества

Analytical Methods for Geochemical Exploration covers chemical analysis methodology mainly for the determination of base metals and precious metals in geochemical exploration samples. It is meant for the practicing analyst. No principles of geochemical exploration are included since this constitutes specialist material that has been the subject of other books (1, 2). The theory of chemical analytical methods has been kept to a minimum. Complete procedures have been provided in most cases so that no additional sources are necessary to finish the analyses. To avoid misinterpretations, the authors' descriptions of equipment and reagents have been left as complete as possible.
