Furthermore, this study reveals a lower Na 2 O content of K-feldspar grains in the matrix than that of the K-feldspar porphyroclasts (Table 2), which is interpreted as the result of a solid-state diffusion of Na from the K-feldspar matrix to the adjacent plagioclase matrix (Tsurumi et al., 2003; Cisneros-Lazaro et al., 2019).

On the unweathered surfaces the feldspars are still fresh and glassy-looking. On the weathered surface much of the feldspar has been altered to the chalky-looking clay mineral kaolinite. Oxidation is another very important chemical weathering process. The oxidation of the iron in a ferromagnesian silicate starts with the dissolution …
