| Zusammenfassung |
| Quantification of granite textures and structures using a mathematical model
for characterization of granites has been a long-term attempt of
mathematical geologists over the past four decades. It is usually difficult
to determine the influence of magma properties on mineral crystallization
forming fined-grained granites due to its irregular and fine-grained
textures. The ideal granite model was originally developed for modeling
mineral sequences from first and second-order Markov properties. This paper
proposes a new model for quantifying scale invariance properties of mineral
clusters and voids observed within mineral sequences. Sequences of the
minerals plagioclase, quartz and orthoclase observed under the microscope
for 104 aplite samples collected from the Meech Lake area, Gatineau Park,
Québec were used for validation of the model. The results show that the
multi-scale approaches proposed in this paper may enable quantification of
the nature of the randomness of mineral grain distributions. This, in turn,
may be related to original properties of the magma. |
