### The Major Elements  
The contents of SiO\({}_{2}\) (65.73-88.75%), Na\({}_{2}\)O (2.19-9.04%), K\({}_{2}\)O (0.16-10.30%), and Na\({}_{2}\)O + K\({}_{2}\)O (3.97-13.67%) are very high, while the contents of CaO (0.10-0.63%), Fe\({}_{2}\)O\({}_{3}\) (0.37-1.18%), MnO (0.01-0.04%), P\({}_{2}\)O\({}_{5}\) (0.03-0.19%) and MgO (0.01-0.13%) is relatively low; the TiO\({}_{2}\) content of most samples are lower than the detectable level. The ratios of Al\({}_{2}\)O\({}_{3}\)/ (CaO + Na\({}_{2}\)O + K\({}_{2}\)O) (A/CNK) range from 1.27 to 6.82, and the ratios of Al\({}_{2}\)O\({}_{3}\)/

All the samples fall in the peraluminous range in the A/NK-A/CNK diagram [30] (Figure 6). In the Harker diagram, with the increasing of content of SiO\({}_{2}\), the contents of Al\({}_{2}\)O\({}_{3}\) and P\({}_{2}\)O\({}_{5}\) decrease, while Fe\({}_{2}\)O\({}_{3}\) increases (Figure 7). The alkaline components are another situation. Not the content of Na\({}_{2}\)O or K\({}_{2}\)O, but the sum of Na\({}_{2}\)O and K\({}_{2}\)O manifests excellent linear negative correlation with that of SiO\({}_{2}\). Moreover, although the relationship between Na\({}_{2}\)O and K\({}_{2}\)O is not obvious, the samples from the wall zone are notably different from those of other zones, which definitely illustrate the abitization of K-feldspar (microline). The variability of CaO, TiO\({}_{2}\) and MgO is not obvious.
