The author introduces the basic feature of ductile shear belt and ore-contained term from Maopai gold deposit. By the fault valve-earthquake pump-cyclically healed framework, the dynamic mechanism of fluid coupled ore-forming term, the procedure of this shear zone's forming and mature is explained. Meanwhile, the author discusses this shear belt tectono-dynamics promoting the process of themetallogenie system, handling the operating mechanism, controlling the movement and geometry of the ore-forming substances, and the ore-form ing procedure, capacity and the diference.
The Daxin gold deposit is discovered in Baimashan to Eastwest of Longshan on central region in Hunan in the recont, it has been a large deposit. The article elaborates region metalloginc geology background. It also described the mineral area geologic, strata, structure, the magmatite and country rock alteration in detail, etc. On the basis of the geological charcteristics and field wok of us, we concluded indicator of Daxin gold deposite. The detection of the Daxin gold depo site will seek a mineral to provide new way of thinking next move for this area.
The Shanhou gold deposit at Eastern Shandong is located in the middle-south of the Zhaoping ore-forming belt. The ore body is controlled by the tectonic of the fault strictly , it has some features which are multi-periods and multi-stage. By the basis of analysis about ore-construction and ore-controlling rule, it can be founded that the ore bodies in this region are equidistaneed on the surface, it has the ore body outputted from the north to the south in the vicinity of 36, 18, 0, 120, 90, Zhaoping Fault and Heihushan Fault near the line of 18.0 are the fault-intersection site, the output of gold ore is relatively large, by the influence of Heihushan fault, 1-1 ore body and 1-2 ore body tilt from south to west, it is contrary with the ore body on Zhaoping Fault which is generally tilt from north to east. According to the tilting features of ore body, forecast the characteristics of deeply output, and hope we call follow it in the future.
There are two main types of gold in western Shandong province：volcano hydrothermal type and greenstone belt. volcanic hydrothermal gold metallogenic is rich of source material, with a powerful thermokinetic for forming deposits and formed a series of large and medium-sized gold deposits. But the source material, the therm okinetic for forming deposits and the space of the mineralization structure and so all about green belt gold deposits have a congenital deficienc, so it can only form small gold or mining points. In summary, the ore-searching direction in western Shandong province is mainly the complex body at Yanshan Period of the volcan ic hydrothermal type gold deposits.
Xilaokou gold deposite is in the north of the Jiaolai basin, Mouping and Jimo fault zone is an important regional-fault, it controls the basis tectonic morphology of this regionl, and it makes the tectonic of the fault zone on this area towards Northeast. The east of this region is close to Pengjiakuang gold deposite, the west of this region is close to Liaoshang gold deposite and Tudui gold deposite, so the conditions about the formation of gold deposite is relatively better. This thesis analys the geological conditions about the formation of gold deposite Oll geochemical, geophysical, tectonic and other aspects, finds the ore guide, and evaluates the vision about the constitution of gold deposite on this regional.
The Hulalin gold deposit is located in the Southeast border of Siberlia Plate, and refers to the zone between the noah Wuma-xikouzi uplift and the of southeast of Badaoka- Enhehada Middle Jurassic depression. The genetic type belongs to the meso-epithermal altered hydrothermal. The ore bodyies are controlled by SN trend falt The ore bodies trend roughly in SN diection. The average grade of gold is 1.40∽3.70×10-6, the t0p grade is 137.0×10-6. The ore-forming age was 135.5 Ma. The temperature of gold mineralization is 320℃∽360℃. The prospecting criteria is patent. It will be good prospecting exploration direction for the outside orebodies.
The gem of Lvdongling at Dawu in the North Hill Qiliang county is controlled by the layer rock of Cambrian．Which form most because the siliceous rock metamorphose to for law—mid temperate rock fliud．So the rock of siliceous nature become the principal sign find gem there．
Nachitai gold mine located in carbonate rock Wanbaogou group．Its orebo dy locality and scale is controlled by diggings main structure north west high angle pressing faultage hypo-grade structure．Where there is silicify arsenopyrit and pyriteization sometimes forms make of ore．This article is based on geological characteristics of diggings，analyzed the characteristics of forming mine and cause of forming orebody．
Qinghai southern part Moyun—Dongba alga covers 27 800 km，the uranium element abnormal area enclosed out amounts to 2 700 km ，the intensity and scale are equal better than that the uranium mine body's abnormal of the East Kunlun Mountains already discovered，the uranium minerization clue already was discovered in MoYun-DongBa，accelerating whose an atomy investigating and verifying acourse has important practical or immediate significance to the North of Three River，even the whole province's uranium mine resource prospecting．By the fact that the abnormal characteristic analysis，the text choice 3 gets that is important target region to study the granite type uranium mine，it should arrange next step working as soon as possible．The same time，the field soaks the sandstone type uranium mine should be paid closeing attention to the unconform ity face among rock masses and third departments developing．
The content of gold in the gold ore containing arsenic,sulphur and lead is about 17 to 18g/T，and the gold ore contains 20.1～20.5(mass fraction)arsenic,18.46% sulphur and 3.05% lead,which restricts the cyanide leaching rate also disturbed by other elements within 5%～10%.However,the gold leaching rate reaches 80%-85% with the existence of anti-film agent and activator after the ore is oxidized for 12～15 h.Moreover,the gold leaching rate reaches beyond 90% after cyanide leaching for the second time,which can benefit a lot.
The gold of some burmese charcoal gold ore containing arsenic，cuprum is one of the minerals which is difficult to soak.Straight taking over the use of the carbon thick liquid craft cyaniding leaching，the gold leaching rate is 60%.The copper in the mineral is easy to forms the Cu(CN)2 precipitations covering on mineral surface during the cyaniding process，which will hindrance the further gold cyaniding response．In our study after adding the help-soak reagent into the gold ore，some minerals have the chemical reaction with it，increasing the gold cyaniding speed，the leaching rate has achieved 90%～92%.
For develop the DA SHA LONG Iron Ore in Qing Hai Province，the company of special steel group limited liability in Xi Ning entrust the Mineral Product And Smelting Research Institute in Chang Sha to the Mt and Mt_Sd of the DA SHA LONG Iron Ore proceed test on exploring，then find out the eligibility of that iron ore，for the geology of ore evaluation provide science experiment.The result showing：that the DA SHA LONG Iron Ore is not suitable for the developing exploiting under the economic technique at now.
