Basic Concepts of Geochemistry and Composition of Earth Materials,ytical methods can be classified into eight major groups. The lower limits of detection (LODs) of most instruments are not random numbers but obey the odd–even effect of nuclear stability. From an extensive database of Pliocene to Holocene fresh igneous rocks, we illustrate the way statistics and co

Trace Element Geochemistry, diagrams for tectonic discrimination. The need for normalization in multi-element diagrams is made clear. This is followed by quantitative applications of trace elements in multi-element normalised diagrams. A worldwide compilation of the Nb and Ta anomalies is presented and its importance for the

Basic Concepts of Statistics,respective quality terms (precision and accuracy) as well as the analytical uncertainty, are explained. A day to day example of gasoline (petrol pump) is used to explain these terms. The historical development of geochemical reference materials (GRMs) for quality control in geochemistry and the stat

Handling of Univariate Data,traditionally, this branch of geosciences (geochemistry) is based on such statistical information. The common but erroneous practice in geochemistry of measuring an “unknown” sample only once is pointed out. The major and trace element data of geochemical reference materials (GRMs) would approximate

Discordancy Tests for Univariate Data,h are of great importance in appropriate handling of experimental data. The pre-1950 population-based outdated procedure commonly encountered in most books has been shown to be invalid and probably statistically incorrect for handling of finite-sized experimental data. The statistical correct post-

Significance Tests,ta. The current practice to document data quality in a geochemical study is to simply present the measured concentrations of major or trace elements in geochemical reference materials (GRMs), along with the literature values in a table. We present the four-step procedure . for the relevant statistic
