Gresens' initial ideas about the mobility/immobility of elements and the gains and losses of
material in hydrothermal systems, together with the subsequent isocon method proposed by …

Mass balance calculation is a fundamental approach in geosciences. In petrology and
geochemistry, it is widely used for quantitative characterization of phase transition and mass …

The isometric logratio transformation, in the form of what has been called a “balance”, has
been promoted as a way to contrast two groups of parts in a compositional data set by …

Conclusions OPTIMASBA is a user-friendly tool for modelling—easily and effortlessly—all
the processes involved in the differentiation of magmatic rocks by considering major …

We provide a new algorithm for mass‐balance calculations in petrology and geochemistry
based on the log‐ratio approach championed initially by John Aitchison (eg, Aitchison …

Rock alteration processes can be studied through geochemical Mass Balance (MB)
estimation in several ways. Due to the ease of its adaptability, especially its graphical …

The current theoretical development of the analysis of compositional data in the article by
Aitchison and Egozcue neglects the use of Harker's variation diagrams and other similar …

MODAN is an interactive computer program written in Microsoft QuickBASIC to estimate
mineral quantities (modes) based on bulk and mineralogical compositions of rock, soil and …

Geoiso is a computer program for WindowsTM platforms that calculates and plots the mass
and volume changes that can occur in a wide variety of open system geological processes …

This study complements the isocon method of for describing mass transfer during
metasomatic alteration by introducing a normalization solution to illustrate sequential mass …
