Melt inclusion vapour bubbles: the hidden reservoir for major and volatile elements

Liquids with vapour bubbles

We propose a model for liquids with bubbles calling upon the theory of continua with microstructure. In addition to the contraction and expansion of bubbles due to pressure already included in models available in the literature on such continua, we take into account possible phase changes at the bubble surfaces. To begin with, we consider here the simplest constitutive assumptions for both phas...

Transport of metals and sulphur in magmas by flotation of sulphide melt on vapour bubbles

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Apatite-Melt Volatile Partitioning Under Lunar Conditions

Introduction: The volatile component of apatite [Ca5(PO4)3(F,Cl,OH)] makes it a popular choice for studying the abundance and distribution of indigenous lunar volatiles [e.g. 1-5]. The thermodynamic behavior of volatile partitioning into apatite is, however, poorly constrained. Limited experimental studies of apatite/melt partitioning have focused on terrestrial systems [6], chlorine-brine syst...

Equations for the Keplerian elements : Hidden symmetry

We revisit the Lagrange and Delaunay systems of equations for the six osculating orbital elements, and point out a previously neglected aspect of these equations. A careful re-examination of the derivation of these systems shows that in both cases the orbit resides on a certain 9-dimensional submanifold of the 12-dimensional space spanned by the osculating elements and their time derivatives. W...
