Luziyuan lead-zinc deposit located in Fengwei, Zhenkang,Yunnan Province, at the direction of 140°, horizontal distance is about 10km. The deposit closely related to acidic magmatism and geological structure. According to the latest exploration results of Yunnan Geological Survey, the amount of lead-zinc resources is 280 million tons, it is super-mega deposit. Mineralization factors as tectonics, deep fault, concealed rock, ore formation and surface north-east trending fault zone control the formation of the deposit. Gravity abnormal, magnetic abnormal, geochemical abnormal and associated mineralization of the mine relate to prospecting potential.

2D Electrical Resistivity (ER) and Instantaneous Potential (IP) geophysical techniques were used at Eziama village in Abia state of Nigeria to investigate possible Pb-Zn mineralization. The dipole-dipole electrode configuration was employed for data acquisition and Earth Imager software was used for inversion of the acquired data. The analysis of the result of the study showed the presence of the Pb-Zn ore along traverses 1, 2 and 3 while traverses 4 and 5 appear barren. Along traverse 1, the mineralized zone falls within the fractured basement and is characterized by low resistivity (about 316 – 5623 ohm-m) and high chargeability (33.2 – 128 ns) at lateral distance of 73 – 103 m. On traverse two, the ore body was identified at lateral distance of about -18 to 53 m as delineated on the IP structure with resistivity and chargeability of the anomalous zone ranging from 4.6 – 677 ohm-m and 41.8 – 142 ns respectively at depth of about 21.4 m while on traverse three, two ore bodies labeled a, a’ and b, b’ on the ER and IP cross-sections were delineated at lateral distance of about -130 to -93 m and 78 to 98 m respectively with depth to the top of the suspected ore bodies ranging from about 7.1 m for body ‘a’ and about 14.3 m for ‘a’. Traverses four and five however showed no prospect for Pb-Zn mineralization. The result of this investigation has once again demonstrated the usefulness of combined electrical resistivity and induced polarization techniques in solid mineral exploration.

The paper introduces a number of new research results on the characteristics of lead - zinc ores in Phia Dam - Khuoi Man areas based on the application of traditional geological methods, combining the method of researching material composition and method statistical maths. In the study area, there are two forms of ore bodies with characteristics described as below: the first form consists of ore bodies developed along the stratabound bedding surface, are mainly distributed in either anticlinal structures (i.e. Phia Dam region) or cuesta (i.e. Khuoi Man region) and the second form consists of ore bodies in lodes, filled in cracks or zones of fracture along the northwest – southeast faults. Primary ore minerals are mainly galena, sphalerite, pyrite, chalcopyrite, etc. and gangue minerals are calcite, dolomite, and quartz. Ore structures are nests, veins, disseminated veins, banded, speckled, or sometimes breccia - like ones. The relevant and controlling factors of lead-zinc mineralization in Phia Dam - Khuoi Man region are the northwest - southeast fault system and the lithostratigraphy. Ores are of either mesothermal or epithermal deposits (temperatures varies from 162 to 308 degrees Celcius), with a specific symbiotic combination of quartz - sphalerite - galena - chancopyrite.

: The Xi’ao Cu-Sn polymetallic deposit is located in the inner alteration zone of the Laoka granite. The ore bodies extend to 400 m in the granite rock and primarily occur with fluorite and potassic alterations. Two cassiterite samples of altered rock-type ore and one tourmaline vein-type ore in the Xi’ao Cu-Sn polymetallic deposit yielded U-Pb ages of 83.3 ± 2.1 Ma, 84.9 ± 1.7 Ma, and 84.0 ± 5.6 Ma, respectively. The Raman spectrum peak values of A1g were shifted to a lower frequency, possibly due to the substitution of Sn with Nb, Ta, Fe, and Mn. Measured δ18O values of cassiterite samples and calculated δ18OH2O values for the ore-forming fluid indicate that the latter was mostly derived from magma. The high Fe and Mn abundances for cassiterite are consistent with those of hydrothermal origin. The Nb, Ta, and Ti contents indicate that cassiterites in the Xi’ao deposit likely formed in a metallogenic environment that was largely affected by granitic magmatism. Therefore, we conclude that the Xi’ao deposit is a magmatic hydrothermal deposit.

Pot experiments with three local legumes (Trifolium repens L., Vicia Cracca L., Medicago sativa L.) were conducted in five different amendment substrates to research into the revegetation in Lanping, Yunnan province. The main factors of restrict growing of vegetation are lack of nutrient, high concentration of Pb 2+ and Zn2+ , poor in water-holding capacity in lead-zinc tailings. Trifolium repens L. and Vicia Cracca L. are taken as pioneer plants of lead-zinc tailings according to characteristics of the three local legumes species during the growth periods about indexes of the seeding survival, height, biomass, chlorophyll content, SOD (superoxide dismutase) and CAT (catalase) activity, TF75 (75 percent tailings soil + 25 percent rural soil) amendment approach is more reasonable for the revegetation of lead-zinc tailings in Lanping based on three local legumes species growth indexes and feasibility.

Luziyuan lead zinc iron metal mining area is located in the south of Baoshan-Zhenkang lead, zinc, mercury, rare metal mineralization belt of the southwest Sanjiang metallogenic belt.According to the mine tunnel drilling and logging data, that the ore bodies are controlled by strata and faults, symbiosis and Dali rock, limestone, near ore wall rock skarnization strongly, the research shows that the deposit belongs to sedimentary transformation - skarn Pb Zn Fe polymetallic deposit. [ Mining area within the range of 1:50000, 1:50000 gravity measurements of soil geochemical survey, combined with the large scale mapping of data discovery lead zinc iron copper resources are expected to find in the eastern Luziyuan area Mangxi - Head Mountain Luojiazhai resource replacement area.
