Exercise 7.2 Naming Metamorphic Rocks. Provide reasonable names for the following metamorphic rocks: A rock with visible minerals of mica and with small crystals of andalusite. The mica crystals are consistently parallel to one another. A very hard rock with a granular appearance and a glassy lustre. Figure 4.1.1 4.1. 1: Porphyritic texture. Some igneous rocks have a mix of coarse-grained minerals surrounded by a matrix of fine-grained material in a texture called porphyritic. The large crystals are called phenocrysts and the fine-grained matrix is called the groundmass or matrix. Civil Engineering.

The opposite is true for calcite and quartz. The dissolved grain boundaries indicate grain size reduction by pressure solution (Fig. 5 a–b). Microstructural observations of fault gouges have shown that grain size reduction may occur over a wide range of slip rates and different deformation mechanisms (Stünitz et al., 2010).

4.1.2 Planimetric Procedure— The planimetric method involves an actual count of the number of grains within a known area. The number of grains per unit area, NA , is used to determine the ASTM grain size number, G. The precision of the method is a function of the number of grains counted. A precision of ±0.25 grain size units can be …
