Physics and Chemistry of Partially Molten Rocks

Abstract

Cover illustration: Secondary electron photographs of fracture surfaces of quartzites synthesized in the presence of small volume fractions of various fluids. a Quartzite containing"'0.2 voI. % of hydrous granitic melt (8= 14°; P-T-t conditions are 900 °C -lGPa-159 hr; from Laporte et al., 1997, Fig. 7): melt forms an interconnected network of grain-edge channels (edges along which the glass has been destroyed during sample preparation appear rounded).

Advantages of a conservative velocity interpolation (CVI) scheme for particle‐in‐cell methods with application in geodynamic modeling

“…Chemical heterogeneities play an important role in mantle dynamics and an accurate numerical method to treat them in geodynamic models is of prime importance [Tackley, 1998;McNamara and Zhong, 2004]. Several techniques are used to track the composition field in computational fluid dynamics, and the particle-incell method (PIC), which advects composition-carrying particles with the ambient velocity field, is found to be a very flexible and robust method to model many geodynamical problems [Van Keken et al, 1997;Tackley and King, 2003] and is commonly used in the mantle convection community [e.g., Van Keken et al, 1997;Schmeling, 2000;Gerya and Yuen, 2003b;Moresi et al, 2003;Tackley and King, 2003;Ballmer et al, 2009].…”
