# Construction, Test and Application of a Tungsten Metallogene Named MGW11: Case Studies in China
## 3 Test of MGW11
### Results  
Based on the reported elemental concentrations of samples from each weathering profile, weathering indices including CIA and WIG, acidic similarities (\(R_{\text{Acidic}}\)) of LG01 and LG03 lithogenes, samples' similarities relative to the top soil and the bottom bedrock, mineralization similarities (\(R_{\text{IdealOre}}\)) of MGW and MGW11 metallogenes are calculated for each weathering profile and illustrated in Figures 3 and 4. The CIA (chemical index of alteration) was developed by [PERSON] and [PERSON] [18] in reconstructing paleoclimate from Early Proterozoic sediments, and the WIG (weathering index of granite) was proposed by [PERSON] et al. [19] to describe the weathering degrees of weathered granitic products in the absence of CO\({}_{2}\) contents. The calculation methods used here were detailed and described by [PERSON] et al. [8]. The calculation methods on gene codes and similarities used here can be found in Reference [1]. Acidic similarities (\(R_{\text{Acidic}}\)) of LG01 and LG03 in each profile were calculated firstly to check whether their products are 11 types of LG_CR or not. The gene similarity (\(R\)) of samples is calculated relative to their bedrock (heredity property) labeled as \(R_{\text{Bedrock}}\), their top soil (inheritance property) labeled as \(R_{\text{Topsoil}}\), and the ideal ore (mineralization similarity) labeled as \(R_{\text{IdealOre}}\) respectively in each weathering profile (Figures 3 and 4). \begin{table}

Table 2: Information on weathering profiles. Figure 3: Weathering indices and gene similarities of samples from weathering profiles of DH31, TL19D04, LHK55, and LC19. (**a–e**) are the weathering indices, acidic similarities, similarities of MGW, similarities of MGW1, and mineralization similarities respectively in profile DH31. (**f–j**) are those in profile TL19D04, (**k–o**) are those in LHK55, and (**p–t**) are those in LC19. The CIA values of samples from DH31, TL19D04, and LHK55 profiles range from 49.8 to 56.6, from 50.9 to 57.4, and from 49.2 to 57.6, respectively (Figure 3a,f,k). The WIG values of samples from these three profiles range from 68.5 to 89.8, from 64.6 to 86.9, and from 63.6 to 94.3, respectively (Figure 3a,f,k). According to the classification values of 60 and 80 on CIA [20] and values of 20 and 60 on WIG [6; 8], these three profiles have undergone incipient weathering. While CIA values of samples from LC19, LY18D13, and LY18D06 profiles in south China range from 53.0 to 94.1, from 59.8 to 83.6, and from 50.7 to 93.1, respectively (Figures 3p and 4a,f). The WIG values from these three profiles in south China range from 5.2 to 76.0, from 15.6 to 67.8, and from 6.3 to 86.1, respectively (Figures 3p and 4a,f). These values indicate that the profiles in south China have undergone extreme weathering.
