Sulfur: Nature And Properties

Session ID#: 26190

Session Description:
Sulfur, a polyatomic nonmetal with 25 known isotopes, and many allotropes and polymorphs, is the tenth most abundant element in the Universe. Sulfur plays a significant role in the redox chemistry and degassing of natural and synthetic melts and, possibly, in triggering of volcanic eruptions. It is also an essential component of all living cells.


Elemental sulfur (Se) occurs in evaporite formations and volcanic settings among others. In its pure form, it undergoes a 10,000-fold increase in viscosity above ~160ºC, due to polymerization. Impurities (including organics) can further play an important role in the chemical and rheological behavior of Se.  We welcome contributions on the chemical and physical properties of sulfur and their implications for understanding melts and magmas as follows: (i) observations of the occurrence of Se; (ii) macro/ micro-analytical characterization of Se from different sources; (iii) experimental observations; (iv) role of sulfur in the redox evolution of melts.
