Geochemical and geological characteristics indicate the wolframite mineralization for seeking the type of wolframite mine in Vau village and ajacent area (Dong Giang district, Quang Nam province)

Wolfram mineralization in the area of Vau village (Dong Giang district, Quang Nam province) is distributed along small stream together with other sulfide mineralizations form to large boulders. Ore minerals are mainly sheelite, pyrhotite, arsenopyrite a little chalcopyrite and pyrite. The ore stockwork type gray, light gray metamorphic sedimentary rocks quartz - mica composition alternated feldspar schist, sericite schist sericitized A Vuong formation (Sequene 3). Sheelite exists manifested by hornflization bezeritization. Ajacent have weak skarnation. They manifestations wolframite deposit skarn type. Geochemical characteristics: W reaches 2,323 ppm (0.023%), As 110,366 (1.10%), Co 212.3 ppm, related granite (Ba Na block’s granite) reaching 1,517 wofram situated at edge magma block (fine-grained alaskite, similar boulders strip). There small-grained content 794 center mass. Thus, two types high level metallogical specialization (Ktt = 397 fine-grained Ktt 758.7 alaskite Granite). Besides, this rock has (277.4 granite, 29.9 alaskite).
