Experimental studies can provide valuable information about volcanic systems, and they can provide quantitative information concerning magma storage conditions, volatile contents, and timescales of magma migration within the earth. The principle types of information that can be provided by experimental studies include phase equilibria (what P-T conditions needed for observed minerals), melt differentiation trends due to crystal- lization, and volatile solubilities (mainly P constraints, based on observed volatile contents of melt inclusions [MIs]). In this chap- ter, we address all of these issues, with particular attention to the relatively alkali-rich magmas typically involved in volcanic activity of the VesuviuseCampi Flegrei (CF) area. We note that experimental studies can also provide valuable information on crystallization kinetics (e.g., Shea et al., 2009; Di Carlo et al., 2010; Arzilli and Carroll, 2013; Arzilli et al., 2016; Romano et al., 2018), mineral reaction rates (e.g., Mollo et al., 2011), timescales of magma ascent and/or magma mixing (e.g., Morgan et al., 2004; Perugini et al., 2010; Iovine et al., 2017), and trace element partitioning behavior (e.g., Pappalardo et al., 2008: Fedele et al., 2009; Mollo et al., 2016), but these arguments are beyond the scope of this chapter, and the interested reader can find further information in the cited references. In the first section of this chapter, we discuss phase equilibrium experiments and the insights they may provide for magmatism in the VesuviuseCF region. Following this, we present the current state of understand- ing concerning volatile solubilities in the typically alkaline melt compositions that characterize magmatic activity in the VesuviuseCF area and compare the available data with the more abundant data available for less alkaline magma composi- tions. These data provide insights concerning volatile element behavior in these volcanic systems and aid interpretation of other studies using MIs for better understanding preeruptive magmatic volatile contents, depths of magma origins, and magma degassing processes during ascent.

Abstract
Experimental studies can provide valuable information about volcanic systems, and they can provide quantitative information concerning magma storage conditions, volatile contents, and timescales of magma migration within the earth. The principle types of information that can be provided by experimental studies include phase equilibria (what P-T conditions needed for observed minerals), melt differentiation trends due to crystal- lization, and volatile solubilities (mainly P constraints, based on observed volatile contents of melt inclusions [MIs]). In this chap- ter, we address all of these issues, with particular attention to the relatively alkali-rich magmas typically involved in volcanic activity of the VesuviuseCampi Flegrei (CF) area. We note that experimental studies can also provide valuable information on crystallization kinetics (e.g., Shea et al., 2009; Di Carlo et al., 2010; Arzilli and Carroll, 2013; Arzilli et al., 2016; Romano et al., 2018), mineral reaction rates (e.g., Mollo et al., 2011), timescales of magma ascent and/or magma mixing (e.g., Morgan et al., 2004; Perugini et al., 2010; Iovine et al., 2017), and trace element partitioning behavior (e.g., Pappalardo et al., 2008: Fedele et al., 2009; Mollo et al., 2016), but these arguments are beyond the scope of this chapter, and the interested reader can find further information in the cited references. In the first section of this chapter, we discuss phase equilibrium experiments and the insights they may provide for magmatism in the VesuviuseCF region. Following this, we present the current state of understand- ing concerning volatile solubilities in the typically alkaline melt compositions that characterize magmatic activity in the VesuviuseCF area and compare the available data with the more abundant data available for less alkaline magma composi- tions. These data provide insights concerning volatile element behavior in these volcanic systems and aid interpretation of other studies using MIs for better understanding preeruptive magmatic volatile contents, depths of magma origins, and magma degassing processes during ascent.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
