Modeling of Magmatic and Allied
Processes presents methods and models for the
quantification of geological processes. Conceptual models for
magmatic differentiation involving crystallization and mixing are
presented and applied to field and textural data. Model equations
for the degree of partial melting in presence perturbations of
lithospheric geotherms and partitioning of trace/radioactive
elements in the matrix and melts, and the formation of
continents with melt additions are described. Â Diverse
magmatic products are shown to result from differentiation
processes rather than magmatic source heterogeneities. The degree
of partial melting depends on mantle temperatures, for which
parameterized thermal convection models are reviewed. Perturbations
in geotherms caused by mantle heat flow, CO2 flux from great depths
and tectonic thrusting are analyzed. The petrogenetic significance
of accessory minerals of felsic magma evolution is assessed with
the help of examples from Carpathian granitoids. Methods for
simulating the 3-D Concentration and Distribution Models (DC-DMs)
and fractal dimension of evolving magma systems are described with
examples. The use of conventional scanning electron microscopy
methods and electron microprobe to characterize and infer magmatic
processes is explained, and the background and economic potential
of hydrothermal systems are examined. The nature of oxidizing
felsic magmas along with their potential for copper mineralization
is discussed. In closing, the handling, calculation and plotting of
geochemical data for igneous rock suites using
the R-language-based software Geochemical Data Toolkit
(GCDkit) along with plug-in modules for the forward and reverse
mass-balance calculation of fractional crystallization are
demonstrated.
