“…6), and observed that the slope of the crystal size distributions (CSDs) decreased with quench temperature. Very similar behaviour was seen in andesitic melts by Iezzi et al (2011), except that the CSDs were more strongly curved. Such behaviour was also seen in the basaltic Makaopuhi lava lake and was interpreted as a result of kinetic growth (Cashman and Marsh 1988), but these textures could also be interpreted to reflect coarsening (Higgins 2006).…”

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...

“…18 Our current understanding of the crystallisation behaviour of anhydrous natural silicate melts relies on previous cooling-induced dynamic crystallisation experiments either ex-situ (Gibb, 1974;Lofgren et al, 1974;1979;1986;Walker et al, 1976 and1978;Bianco and Taylor, 1977;Lofgren, 1977;Grove and Raudsepp, 1978;Donaldson, 1979;Uhlmann et al, 1979;1981;Corrigan, 1982;Fang et al, 1983;Kirkpatrick et al, 1981;1983Tsuchyama, 1983Baker and Grove, 1985;Lesher et al, 1999;Burkhard, 2005;Conte et al, 2006;Faure et al, 2003;Pupier et al, 2007;Walton and Herd, 2007;Orlando et al, 2008;Hammer, 2009;Del Gaudio et al, 2010;Iezzi et al, 2008;2011;Mollo et al, 2010;2011;Vona and Romano, 2013 and references therein) or in a few in-situ (Sunagawa, 1992;Schiavi et al, 2009;Ni et al, 2014).

For each run-product, the identification of phases was determined by linking their grey-level ranges with the compositions.…”

“…The area% of each phase was quantified by translating differences in gray levels to the area% of glass, clinopyroxene (cpx), spinel (spl), plagioclase (plag), olivine (ol), biotite (bt), and bubbles. We did not apply a stereological correction, in order to avoid any mathematical manipulation of the data (Iezzi et al, 2011). This method has been used recently by, e.g., Vetere et al (2013a) to quantify the phase proportions in systems containing typically 4 phases (glass, pyroxenes, plagioclase, spinel).…”
