Green River County, Burgenland region of gold and gold quartz veins Relations
Do not up to 2m,[link widoczny dla zalogowanych], extended range from a few meters to tens of meters,[link widoczny dla zalogowanych], and some up to one hundred meters, like Zha Kete gold mining areas like the east wall of a quartz vein rock is very long. Quartz veins or in the tendency toward the presence on both the expansion and contraction,[link widoczny dla zalogowanych], sharp reproduction of l off the branch complex phenomenon. In the altered fracture zone in order to smooth the output layer of quartz veins is most developed,[link widoczny dla zalogowanych], the general occurrence of 30 ~ <70. l ~ 30. \See also a ramp or cut the level of output layer a hundred veins, usually in l0cm thickness of about the length of more than a few meters range. Due to stress effects, some of the veins along the local level of output changed significantly, resulting in complex and diverse forms veins. Quartz vein ingredients were simple, the main ingredients of quartz, followed by iron carbonate, about 5% concentration, and other mineral content is low, generally less than 2%, including pyrite (limonite), galena, sphalerite ore, chalcopyrite, arsenopyrite, sericite, chlorite. Altered compared with pure quartz vein in the majority of non-metallic minerals, including an advanced generation of non-quartz. Quartz with metal sulfide ore body or mineralized bodies generally form, the study of the four major ore deposits are the polymetallic sulfide bearing quartz veins, and native gold. 2. Quartz veins and gold Burgenland region between the main gold mineralized quartz vein intensity is closely related to the development of the situation. Enrichment of gold is mainly affected by the control of quartz vein, the specific performance of the following aspects: (1) gold ore constituted mainly by quartz veins, followed by the amidine next to the altered imprison rock. Surface and deep works reveal more wide-quartz veins, gold body thicker. Engineering and geological sample analysis results contrast to the situation that all operators gold grade samples contain quartz veins, quartz vein ore bodies can be used as prospecting and moreover do not sign. (2) gold quartz veins are generally several times higher than the clock next to the rock, see Table l statistics show that deposits of gold within the quartz veins generally larger than 1xl0 ~, the individual up to 2.64 × 10, while the clock next to the circumference generally less than 0.7x10 a rock, a few around in 1xlO: some surface mining projects in the Zha Kete sampling and analysis of data statistics: grade gold bearing quartz veins of 1 × 『『】 a ~ 59.8 ×】 0 eight samples, the average l3.67 × 10; containing quartz is small, thin veins of schist gold content of 0.12 × l0 a ~ 9.08 × l0 ~; 17 件 sample average 0.91 × 10 '. ', And schist Gookin average only 008 × 10'. ', L0-like pieces. Table 1 Effect of different types, thickness of the vein and the vein next to the stone soup base amount of surrounding homes than: Lei Jinxuan l0 ~; thick pressure m; A: Network Tasman in the card: K: Sample Aqsa by; Z: Zha Kete ; H-Red Hill (3) can be seen from Table 1. Most of auriferous quartz veins as a single pulse, and the thickness is generally greater than 0.4m, the gold content is often higher than the content of small quartz veins, in practical work has been confirmed. (4) gold quartz veins and sulfide veins in vivo characteristics of particularly close (Table 2). Where quartz veins with high gold content, the veins are developed within a certain pension amount of sulfur, generally rich in pyrite, and the other with arsenopyrite, galena, sphalerite and so on. In Zhake Te mine, and sometimes sulfur content is low, less than 1%, but rich in native gold, there will be extra high grain bits. Sulfide quartz veins focal points of Xinjiang Nonferrous Metals 2000 3 cloth uniform, go on in the same vein, due to sulphide content and gold grade also will be changes, such as KI8 and K19 samples, reflecting the gold veins and vein r proportional to the sulfide content. Yuan Fu 2, amidine empty quartz veins containing sulfide emptiness characteristic relations with depression Z · Zhate: Royal Stratas. K: Branch, Sa Kang. (5) clock next to the veins surrounding the gold content and gold content of the relationship itself (Table 1). In general the gold content of rock adjacent to veins and quartz vein gold content is proportional to gold-bearing veins is greater than 1x10 ~, gold-bearing veins next to the rock more in 03x10 for a general l × 10 \× 10. rock gold veins also inversely proportional to the distance, as shown in Figure l and Table 3. Even low levels of quartz vein itself, there is a certain vein wall rock adjacent to the mineralization, as shown in Table l of the Z168 like. (6 ) gold-bearing quartz veins within the mineral distribution is very uneven, and in the tendency to change quickly are shown in Figure 2.
