“…It hosts about 73% of the tungsten resources (9.943 Mt WO 3 ) and 85% of the tin resources (6.561 Mt Sn) of South China (Mao et al, 2020). International interest in tungsten deposits in the Nanling Range originated from early geological work during the 1940s (Hsu, 1943), and both theoretical study and exploration of W-Sn mineralization has continued for more than 80 years (e.g., Hua et al, 2003;Mao et al, 2011;Yu, 2011). The widespread W-Sn deposits in the Nanling Range are spatially and genetically associated with the late Jurassic granites (Yin et al, 1995;Wang et al, 2003), and the focus of this study is the Xitian Triassic-Jurassic composite batholith (Fig.…”

There are two factors, source composition and magmatic differentiation, potentially controlling W–Sn mineralization. Which one is more important is widely debated and may need to be determined for each individual deposit. The Xitian granite batholith located in South China is a natural laboratory for investigating the above problem. It consists essentially of two separate components, formed in the Triassic at ca. 226 Ma and Jurassic at ca. 152 Ma, respectively. The Triassic and Jurassic rocks are both composed of porphyritic and fine‐grained phases. The latter resulted from highly‐differentiated porphyritic ones but they have similar textural characteristics and mineral assemblages, indicating that they reached a similar degree of crystal fractionation. Although both fine‐grained phases are highly differentiated with elevated rare metal contents, economic W–Sn mineralization is rare in the Triassic granitoids and this can be attributed to less fertile source materials than their Jurassic counterparts, with a slightly more enriched isotopic signature and whole‐rock ɛNd(226Ma) of −10.4 to −9.2 (2σ = 0.2) compared with ɛNd(152Ma) of −9.2 to −8.2 (2σ = 0.2) for the Jurassic rocks. The initial W‐Sn enrichment was derived from the metasedimentary rocks and strongly enhanced by reworking of the continental crust, culminating in the Jurassic.

“…Complexity science and nonlinear science theory are seldom applied in this area. Only Yu Chongwen 21 – 23 used complexity theory in his works to explain the mineralization of the Nanling area. Yu Chongwen 24 , 25 pointed out that the combination of mathematics, chemistry, physics, nonlinear science, and complexity theory with geological science facilitated a long-term exploration of the nature of geological phenomena and addressed the basic problems of geological sciences.…”

The topological classification of geochemical elements is widely used as a reference for regional prospecting prediction. In this study, we analyze the topological correlation structures of 39 representative geochemical elements from the Nanling area of South China by implementing the complex networks theory. The topological correlation structures of geochemical elements have a high clustering coefficient (0.8120–0.8880), but the magnitude of the shortest path (1.2950–2.3600) is small. In combination with the analysis of complex networks characteristics, we report that the topological correlation structures of the geochemical elements in this area have small-world characteristics, which reveals the self-organized criticality. As shown in the topological network, two random elements have some level of associations, which present a specific community feature. Our preliminary result shows that with changing the control parameter (k) of “coarse-graining”, the topological correlation structures undergo two critical phase transitions. As the control parameter (k) reaches 0.44, the entire element system evolves into two parts. When the control parameter (k) reaches 0.63, the system forms three “communities”. It is worth noting that the three “communities” are basically consistent with the Goldschmidt’s geochemical classification of the elements, which are lithophile, siderophile, and chalcophile groups, respectively. In these “communities”, we also found that a small level of component units is nested.
