The effect of thermal history on the development of mineral assemblages during infiltration-driven contact metamorphism
Article Abstract:
A one-dimensional model considers conductive and advective heat transfer, fluid flow, and mineral reaction to predict the temporal and spatial distributions, and the identity of mineral assemblages formed due to contact metamorphism of siliceous dolomite. Comparisons of the results to those obtained from transport models assess the importance of heat flow analysis. The assemblages that are insensitive to thermal history are useful for studying contact metamorphic fluid flow irrespective of heat flow data. The model is applied to the analysis of fluid flow of different aureoles.

Structurally controlled fluid flow during contact metamorphism in the Ritter Range pendant, California, USA
Article Abstract:
A study was conducted on the contact metamorphism in the Ritter Range pendant, central Sierra Nevada, CA, to analyze the fluid flow during such metamorphism. Qualitative analyses of all samples of siliceous limestone, siliceous dolomite and calc-silicate hornfels were obtained by energy dispersive spectrometry. Results showed that the geometry and amount of fluid flow during contact metamorphism in the Ritter Range are constrained by the O-isotope geochemistry and mineralogy of siliceous limestones.
