Eight new geochemical reference materials for the analysis of major and trace elements in
typical geological matrices have been prepared, and their physical and chemical …

In this paper we report the simulation procedure along with new, precise, and accurate
critical values or percentage points (with 4 decimal places; standard error of the mean< …

Abstract The Los Tuxtlas volcanic field (LTVF) of late Miocene to Recent age is a key area to
understand the consequences of the current subduction of the Cocos plate beneath the …

In this study, we used the modified Horwitz expression (Hc= 0.01 c0. 8495, which gives the
precision as a function of concentration) to evaluate and control the accuracy of results of …

In two earlier papers (Verma and Quiroz–Ruiz, 2006, Rev. Mex. dene. Geol, 23,133–161,
302–319) precise critical values for normal univariate samples of sizes n up to 100 have …

In this paper, the modifications of the simulation procedure as well as new, precise, and
accurate critical values or percentage points (for the majority of data with four decimal …

Analogous to chemometrics, geochemometrics can be defined as the science resulting from
the combination of statistics, mathematics and computation with geochemistry. This term in …

En este trabajo se presentan tres nuevas ecuaciones mejoradas del geotermómetro de
Na/K obtenidas a partir del análisis de una base de datos geoquímicos mundial más …

Generation of electricity at the Las Tres Vírgenes (LTV) geothermal field, Mexico, began in
2001. There are currently nine geothermal wells in the field, which has an installed electricity …

Basically, two main types of statistical methods–robust and outlier-based–are available for
handling experimental data; we document here the application of the outlier-based method …
