Tips and Tricks for dealing with geo(logical) data in R

Preface Making maps is an essential (in fact, often THE essential) part of working with spatial data. Your analysis is only as good as your ability to communicate the results to the decision makers.

Modeling the solubility of minerals in water with PHREEQC from R

Preface When working with contaminated groundwater, complex interactions between different solutes and sometimes the aquifer geology itself can lead to a plethora of reactions, potentially creating additional or even completely new problems, when it comes to remediation.

Kriging with R: Exploring gstat

Back in June I wrote a post about the basics of geospatial interpolation in R that, according to Twitter, resonated with a lot of people. It appears that there is a need for detailed tutorials on how to apply geospatial algorithms to real world data (at least in R).

Ionic Charge Balance - a functional approach

When working with water chemistry you are often presented with analytic results either send to you by a lab or probably even measured by yourself. From that analysis (usually from several) you are then supposed to draw insight about what is going on in your river/pond/aquifer.

A practical guide to geospatial interpolation with R

One of the most exciting things you can do with R is geospatial interpolation. This means that you have some kind of information (e.g. measurements of, say, soil temperature) for a limited number of locations and then you apply a mathematical model that will provide you with an educated guess of what your result might look like, if you would have measured at every possible location.

Rhyolite-MELTS vs DERP – Reply to Comment by Gualda et al. on ‘The Effect of Anorthite Content and Water on Quartz–Feldspar Cotectic Compositions in the Rhyolitic System and Implications for Geobarometry’ by Wilke et al. (2017), Journal of Petrology, 58, No. 4, 789–818

Gualda et al. (2018) applied rhyolite-MELTS and DERP to several case studies and noted that DERP has a lower precision and yields distributions of estimated pressures that are significantly different from other geobarometers based on the H2O–CO2 of glass inclusions and amphibole geobarometry. In an attempt to clarify the discrepancy between rhyolite-MELT and DERP, Gualda et al. (2018) describe several problems with DERP. In the following sections we address the critical points mentioned in the comment of Gualda et al. (2018).

The Effect of Anorthite Content and Water on Quartz–Feldspar Cotectic Compositions in the Rhyolitic System and Implications for Geobarometry

The position of the cotectic curve separating quartz and feldspar stability fields in the rhyolite system Qz–Ab–Or(–An–H2O) depends on pressure, making it a potential geobarometer applicable to high-silica volcanic products if melt water contents (H2Omelt) are known.
