Calculation and Illustration of Uncertainty in Geochemical Analyses
Journal of Geological Education, 1985The uncertainty in chemical analyses resulting from precision error should be evaluated and indicated, and error bars should be placed on analytical data when they are plotted in the various diagrams used in geochemistry. The corresponding uncertainty in the sums and quotients that are commonly used (e.g., Na2O + K2O, K/Rb, Fe/(Fe + Mg)) can be readily

Geochemical and palynological analyses of the Serikagni Formation, Sinjar, Iraq
Arabian Journal of Geosciences, 2011Serikagni Formation (lower–middle Miocene) was studied at four outcrop sections within Sinjar Anticline, Para (the western plunge), Jaddala, Sinjar, (Southern limb), and Noaniaa (Northern limb) of Sinjar Mountain, which is part of foothill zone in northwest Iraq.

Geochemical Interpretation of Water Analyses from Tennessee Streams
Transactions of the American Fisheries Society, 1947Abstract The total alkalinity of unpolluted waters in Tennessee streams can be generally related to the nature of the geological formations comprising the stream beds and soil provinces. Data accumulated from 371 localities in streams which are isolated in distinct and separate geological formations show that sixteen geochemical provinces may be ...

Mapping Magmatic and Hydrothermal Processes from Routine Exploration Geochemical Analyses
Economic Geology, 2020Abstract Analytical methods used by commercial assay laboratories have improved enormously in recent years. Inductively coupled plasma-atomic emission spectroscopy and inductively coupled plasma-mass spectrometry methods now report analyses for half of the periodic table with exceptional detection limits and precision.

A graphic procedure in the geochemical interpretation of water‐analyses
Eos, Transactions American Geophysical Union, 1944This paper outlines certain fundamental principles in a graphic procedure which appears to be an effective tool in segregating analytical data for critical study with respect to sources of the dissolved constituents in waters, modifications in the character of a water as it passes through an area, and related geochemical problems.

Geochemical analyses of rocks of the Haparanda suite, northern Sweden
Geologiska Föreningen i Stockholm Förhandlingar, 1984Abstract Thirteen samples of the primorogenic Haparanda suite in Norrbotten, northern Sweden, are analysed for major elements and the trace elements Rb, Sr, Ba, Cu, Zn, Mo, Sn, Be, Nb, Y, Zr, Cr, Ni, V, F, Cl and S. The results accord with the view that the Haparanda suite is an I-type rock suite generated in a compressional environment. The Sn-content

Geochemical and Mineralogical Analyses, Pennsylvanian Kendrick Fauna, Eastern Kentucky: ABSTRACT
AAPG Bulletin, 1982The Kendrick brachiopods of Pennsylvanian age secreted low-Mg calcite shells with average SR2+ content of 1,140 ppm. The crinoids and rugose corals secreted intermediate-Mg calcite skeletons with average Sr2+ contents of 2,140 ppm and 1,770 ppm, respectively.
