### Geochemical Lithogene (LG03)  
The geochemical gene is a new technique presented in recent years [19]. Although the term \"gene\" has been adopted in geochemistry from biology for two decades by [PERSON] and [PERSON] [21; 24; 34; 35] who proposed that the element is the gene of the earth and the geochemical map is the gene map of the earth surface, and another term related to genes is the \"gene profile curve of geochemical elements\" presented by [PERSON] et al. (2015, 2016) [PERSON] et al. (2015, 2016) in geochemistry which is like the REE pattern or spider diagram without gene properties [20; 24], the above two studies do not have the essential connotation of genes, such as codes, heredity, inheritance, variability, similarity, and other characteristics, only the geochemical characteristics of elements. Therefore, it can be regarded as the germination and gestation stage of the geochemical gene. Geochemical genes with these characteristics have just been proposed only recently [24; 25; 28]. \begin{table}

Table 2: Trace element in surface soils, fault muds, and ores. This technique combines the concept of biological gene with geochemistry, and proposes a complete geochemical gene construction process, including gene sequence, gene coding, and gene similarity calculation methods. [PERSON] et al. (2020) proposed that the acidic similarities of genes can be used to classify the composition of rocks, soils, and stream sediment samples according to the characteristics of lithogenes [26]. In recent years, with the development of lithogenes, great achievements have been made in composition classification and provenance tracing [20; 23; 27; 36; 37; 38; 39]. According to the construction steps of a geochemical gene, [PERSON] et al. (2021) proposed a new lithogene labelled LG03 [27]. The gene eliminates the influence of the addition of aeolian sand, organisms, and other media on lithology determination, and is feasible in discussing component classification and provenance tracing. Gene coding and acidic similarities of soils, fault muds, and ones using LG03 lithogene calculate the following (Table 3):  
It can be seen from Table 3 that the acidic similarities of ores are 40-55, the fault muds are 90-100, and the soils are 85-90 (Figure 3j). The proposed lithogene LG02 not only gives a clear meaning to the gene, but also stipulates the division of gene similarity. [PERSON] et al.
