Ore mining area of Jiangxi down (mineralized) phase of the study

Salt scattered in the veins in the upper part of the sulfides are distributed late in the lower low and high sulfur distribution in the upper and early stage mineral filling and replacement. Ⅲ carbonate, wolframite and sulfide phases: distributed in the veins, the upper part of tungsten and tungsten carbonate veins usually in the same vein quartz veins alternate, alternating at the saw in the quartz vein breccia containing tungsten was contained tungsten cemented into brecciated carbonate structures. Veins saw wolframite, scheelite and minor fluorite,[link widoczny dla zalogowanych], sulfides, vein side of a muscovite, carbonate and chlorite. In summary, the mine ore (mineralized) phase characteristics shown in Table 1. As can be seen from the table: (1) metallogenic evolution through a continuous process but show stage, from early to late or from deep to shallow, followed by TR elements appear granodiorite Nb mineralization , Ta, TR element mineralization in two-mica monzogranite Ta, Nb, W,[link widoczny dla zalogowanych], Be mineralization muscovite alkali-feldspar granite (Be), (Rb),[link widoczny dla zalogowanych], w mineralized pegmatite like w, Be, (Rb) mineralization feldspar and quartz veins or quartz feldspar veins w, blo, Bi mineralization quartz vein w, Mo, Bi quartz sulphide mineralization w, S mineralization carbonate veins. (2) from the metamorphic alteration from the hydrothermal metasomatism metasomatism, from morning to night from the bottom of the order of K-feldspar K-feldspar appears weak, weak petrochemical albitization albite, muscovite, weak Yun-ying Yan Liu Jianping, etc. 3: Jiangxi Dajishan metallogenic (mineralization) stage of the study of 19 of a muscovite, electrical petrochemical, fluoritization of a muscovite, fluorite, silicification, sericite mica of a , silicification, carbonation, chlorite. (3) ore-forming elements of the development trend has obvious successor. From morning to night, from the TR-÷ Na, Ta, TR-÷ Ta, Nb, w, Be-÷ (Be), (Rb), W-} W, Be, (Rb) -} W, Be, Mo -} W,[link widoczny dla zalogowanych], Mo, Bi, Table 1Tablel sulfide a w, the evolution of the carbonate sequence. (4) ore-forming conditions change. Structural conditions from the relatively closed to the relatively open; physical and chemical conditions, temperature from hot to cold, high to low pressure, pH from alkaline to acidic and then alkaline, redox environment and then restore from the restore to oxidation.
