“…In some experiments, in an effort to enhance the growth of larger amphibole crystals, the temperature was cycled, with an amplitude of ±10 °C, around the set-point with a period of 30-90 min for several days (Table 3) to promote Ostwald ripening (cf. Mills and Glazner 2013). At the end of the CSV runs, samples were isobarically rapid-quenched.…”

This expression recovers equilibration pressures of our calibrant dataset, comprising both new and published experimental and natural data, to within ±16 % relative uncertainty. An uncertainty of 10 % relative for a typical Al tot value of 1.5 apfu translates to an uncertainty in pressure estimate of 0.5 kbar, or 15 % relative. Thus the accuracy of the barometer expression is comparable to the precision with which near-solidus amphibole rim composition can be characterised.

“…This apparent absence of contacts has been attributed to magma injection into a crystalline mush with movement of melt obscuring contacts (Leuthold et al 2014a;Miller et al, 2011;Wiebe et al, 2004) or could be explained by subsolidus re-crystallisation and textural modification linked to the temperature fluctuations induced by successive magma injections (Mills and Glazner, 2013).…”

“…However, recently it was recognized that temperature cycling, even through a small range, can accelerate equilibration considerably (Simakin and Bindeman 2008). This has been confirmed by experimental observation of plagioclase and olivine textures in a basaltic melt (Mills and Glazner 2013). Temperature cycling is inevitable in convecting magma chambers, accounting for the widespread evidence of equilibration in volcanic and plutonic rocks.…”

SUMMARYDuring the last 20 years, textural (microstructural) studies have regained their place in the pantheon of petrographic methods. This has happened by quantifying textures, so that models can be developed and tested -an approach that has proved to be so successful for chemical and isotopic studies. The combination of chemical, isotopic and textural methods, especially if applied to different crystal populations, can be a very powerful tool in the clarification of petrologic histories of rocks. Here, I will discuss some recent advances in the application of textural studies to crystalline rocks. RÉSUMÉAu cours des 20 dernières années, les études de texture (microstructure) ont retrouvé leur place au panthéon des méthodes pétrographiques. Cela a pu se produire grâce à la quantification des textures, permettant ainsi de développer et tester des modèles -une approche qui s'est avérée très béné-fique pour les études chimiques et isotopiques. La combinaison de méthodes chimiques, isotopiques et d'analyse texturale, en particulier si elles sont appliquées à des populations distinctes de cristaux, peut être un outil très puissant permettant de définir l'histoire pétrologique des roches. Dans le présent article, je vais discuter de certaines percées récentes dans l'application d'études texturales de roches cristallines.Traduit par le Traducteur INTRODUCTION Petrography started in the 19 th century with the development of the petrographic microscope ( Fig. 1; Kile 2003). Initial observations were qualitative, except for modal measurements. However, the development of quantitative chemical and isotopic analysis in the 20 th century somewhat eclipsed traditional petrographic studies and has come to dominate petrology. This is understandable: quantitative measurements do enable more rigorous testing of petrologic models. However, petrography started to regain lost ground about 25 years ago, when quantitative materials science methodology was first applied to petrologic problems (e.g. Cashman and Marsh 1988). Many of the best studies now use a combination of geochemical, isotopic and textural approaches (see review in Higgins 2006).As with all analytical methods, the scale of observation, which can also be considered as the analytical volume, is dictated by the methods used and will provide information on different aspects of the petrological evolution of the rock. For instance, a whole rock chemical analysis provides data on a large volume of material whereas microprobe analyses convey information about individual crystals or parts of crystals. In a similar way, some textural analysis methods supply information on whole crystal populations, whereas others can inform us on individual crystals.There are many definitions of rock texture (microstructure), but the simplest is the geometric arrangement of crystals or other structures in a rock. This is a 'crystal map,' in the sense that it is a simplified representation of the actual structure of a rock. Such maps are actually three dimensional, but are commonly measured or r...
