Primarily for lead, zinc,mulberry outlet, gold mineralization. Quartz vein-type sulfide mineralization in quartz veins at the surface showed fracture zone is composed primarily of quartz vein fragments, limonite, jarosite, etc., in TC11, the quartz veins in the local visible galena, quartz veins of the fracture zone from the TC1, TC3, TC5, TC11 control, long 260m, width of 2.8 ~ 6.4m, lead and zinc mineralization in the TC5 in better lead-zinc body width 1.3m, lead grade 4.3O,abercrombie madrid, 0.30 grade zinc, gold grade of 0.08g / t, silver grade of 60.16g / t, lead and zinc of the body width 4.0m, lead an average grade of 0.31, the average zinc grade of 0.20, the average gold grade of 0 .16 g / t. Carbonate sulfide mineralization in the surface expression of change for the calcareous sandstone,franklin and marshall sale, limonite, sandstone, limonite of change, mostly banded limonite distribution. Mineralization in the quartz vein alteration zone on the fracture zone of the disk, large-scale, long-500m, width 3.3 ~ 21.4m, the TC19, TC15, TC11, TC5, TC3, TC1 controls, in a number of trenches See a lead and zinc mineralization in the TC5, the lead-zinc body width l1.4m,ralph lauren, 0.57 average grade of lead, zinc average grade of 0.23, one sample gold grade of 0.5g / t (width 1. 5m); in TC15, the lead-zinc body width 5.2m, 0.96 grade lead and zinc grade of 0.12, gold grade of 0.08g / t. 3.2 Characteristics of ore mining has not yet been carried out because of the deep drilling project validation, the surface oxide ore have been, galena, sphalerite has been oxidized to brown yellow (on the next page 24) Upper Devonian Tuo Siku Seoul he was black group on sub-group (D. t) is the area of ??ore formation, lead and zinc by the layer of clear and facies control. Previous isotope studies that the D. t is the one source bed rock geochemistry also shows that the formation of Pb, Zn ore-forming elements in high abundance, Pb (21 ~ 61) × 10 ~, Zn (9 ~ 899) × 10 a, Cu ( 41 ~ 80) × 10 a, similar rocks were four times and 19.8 times, as a source bed for the mineralization and mineralization can provide a wealth of mineral. Therefore, with this set is pyroclastic rock ledge,mulberry, lead and zinc point assigns a new set of channel formation, the emergence of these mine sites are closely associated with the containing seam. 2.4.2 construct a large ore-controlling faults from east to west through the southern edge of the mining area,ed hardy vaatteet, it has a structure with raw nature, control of the clastic rocks of the area distribution, the thickness of rocks 4 Analysis of Genesis from the area characteristics of the surface oxide ore containing seam position and point of view, genesis of volcanic-sedimentary type lead-zinc deposits, the ore-forming mechanism is as follows: Zhuo Lesa affected by lead and zinc with gold seam position control, deposit with seam of Lower Devonian Fort group system cambron iron subgroup on the third lithologic (Dk;). Deposits formed in the volcanic eruption of the normal sedimentary strata into the gap, the main lithology of the change limonite calcareous sandstone,ed hardy lippis, and its paleogeographic sedimentary environment should be a low-lying volcanic deposits, including minerals from the volcanic eruption. Chinese ore galena,mulberry oslo, sphalerite (oxidized) mostly of the zonal distribution of the original sedimentary characteristics significantly, but the distribution of the ore body footwall quartz veins, indicating that the hydrothermal lead and zinc, such as by post-transformation, but also easy to the formation of lead-zinc-rich body, suggesting that deep in the deposit, there is the possibility of a larger body of lead-zinc Fuhou. 5 gold prospecting prospective evaluation of lead-zinc mineralization by Zhuo Lesa environment is more favorable, set in the lead-zinc district, are volcanic sedimentary lead-zinc, layer is stable, sulfide ore type lead-zinc carbonate ore, easy to form large-scale lead-zinc. On the other hand, lead-zinc ore in the gold grade is relatively high, as Maizi gold prospecting areas to provide a new exploration target. Therefore, the mine has good exploration prospects,franklin and marshall, worthy of deep drilling project validation. Received: 2008 an l1-13 degrees and facies differences, and thus the overall control of its overall distribution pattern of the mineral. Second-class north west anticline and faults in this area is directly in control of lead-zinc ore body of metal output. Kurt Ga raw lead and zinc produced in the new ditch on an anticline southeast of turning raw Kurt Ga side more times within a small dome, and assigns according to the distribution of fracture North West group. Anticlinal dome transition is to construct a small terminal and the site of stress concentration, fracture and fracture zone is conducive to the formation and development, is the favorable parts of the ore, and its top sheets twist,calzoncillos calvin klein, twist the lower part of the mechanical properties of pressure deep into a more conducive mine. As the ore-clastic strata of brittle, easily broken by tectonic force, resulting in fracture, but also for lead ore mining capacity to create a channel and space. In summary, the area looking for new lead-zinc in the body, expand the size of ore body has broad prospects. Received: 2008 a l0-16
