By the end of 2007，22 industry ore bodies had been compartmentalized in the Zhaishang gold mining area，gold ore reserve(333)+(334)in the mine resource has reached to oversize scale．Discovery of the vein by the fore drill hole is better，the folowing is worse，so the deep project cann t be continued．To preliminary research of thevein behaviour，the ore bodies joined wil be studied further，they have value of further work of deep ore bodies，it is hopeful that the reserve reach to supperlarge scale．
Jijiaogou Gold Deposit is located in northern slope of southern Danghe Mountain in Subei County，Gansu province．It is adjacent with Heieigou gold deposit and Jiagongtai gold deposit．At present，Jijiaogou gold deposit has reached medium —sized，16 veins has been found．The mineralization types are alteration—type and quartz vein—type．In this paper，we discuss every lodes in particular，and obtain the ore deposit genesis by sulfur isotopic characteristies，the components about temperature and pressure of inclusions，and find the prospecting signs of Jijiaogou gold deposit．
Jiaolai basin is a Diwa basin which formatted at Mesozoic．The form ation and evolution of this basin is con．trolled by Yishu fault zone and Wulian—Jimo—Mouping fault zone．In recent years，we discoveres six gold deposits，such as Pengjiakuang，Liaoshang，Tudui，Songjiagou，Dazhuangzi，Xilaokou，and SO on on the border of the basin．This year ，we find Dongxiazhuang and Dahuangjia which has the value for further work in City Laiyang．Jiaolai Basin becomes the hot—spot areas of exploration in Jiaodong．By contrasting and analysising about the time of basin form ation and of the times of the main gold deposit in Jiaodong area．we can see that the main mineralization of Jiaodong gold is similar to the strong extending age of Jiaolai basin．，the form ation and evolution of the basin closely related to
the form ation of the gold deposit in Jiaodong．the ore—form ation conditions about the gold deposit in the basin and the gold deposit in Jiaobei uplift are unanimous，than we find the prospecting orientations．
Based on such factors as regional geological background，strata，structure，magmatite，geophysical and geochemical characters，dynamics of ore—formation system，the author analyses the deposit geological condition ， summarizes its mineralization enrichment rule．The preliminary analysis and assessment of resource prospect is also made．
Researched to start from geological—structural background in Heilongjang eastern area，base rockconstructing，granite distribution，deep—large break characteristic is analyzed，Mesozoic—Neozoic Structural stress—field is restored bv using the three method—geometric parameter of structural formative—tracks，sonic—discharge determine and limiter dimension nuneric imitate．A new viewpoint the early cretaceous structural stress—fields are unproportional in westem zone．middle zone，eastern zone，that late cretaceous and old tertiary structural stress—fields are gY
ral—torsional and that new tertiary structural crush—stress distributed at northwest～southeast direction is suggested．The aera s geological dynamic condition is analyzed； structural occurred，developed and evolved special feature is summed up．Structural information iS provided for analyzing form —mine in the area．
Many places of Tertiary system conglomerate gold deposit have been fond in Huanan area already，Heilonjiang province，it is provided with a good vista for mineralization and it has a big potential resources．It may be areference for the next prospecting work of conglomerate gold deposit after summarizing the clue for prospecting and analyzing its condition of mineralization．
The Sanshierzhan gold deposit is located in the northeast of Erguna rising part，on the edge of Heilongjiang basin of fault subsidence，belonged to the outside of shabaosi gold field．The genetic type belongs to the meso—epithemal deposit of the fracture zone—alterde rock．There are seven mineralization alteration zones in it，including eight oerbodies in the gold deposit．Its highest ore grade is 4．88×10～and average grade is 1．49×10-6． Th e characters of country rock alteration are silicification，schistositizion，carbonatization，sericitization．Th e regional gold mineraliza·tion distribution is mostly controlled by the dome structure．And the Jurassic terreatrial clast depositing rock offers a part of gold source．The prospecting indicators are very obvious．
Sandaogou gold ore is the deposit of Bew type which is found in the middle of the umbo in Jiamusi these years，the distilct is volcanic in Mesozoic．The volcanic actiVity is Violent in the umbo in Jiamusi in Mesozoic，this is an imp0rtant peri0d for forming ore in this district．It may be a reference for finding subvolcanic rocks epi low temperature hydrotherm al gold ore in this district after summailzing the geologic feature and showing some regularity·
The Xiaoyingzi terrene is a typical complex massif，which is characterized by the various lithologic combination．It formed during the intruding of multiperiods magma．It is composed by two independent units and one sequences．The magmatic activity begins from the early Jurassic Epoch and end in the late Jurassic Epoch．The structural environment had transferred form compression to expand，and had obvious character of passive emplacement．The emplacement mechanism was dyke emplacement in the expand mode1．
From the field investigation and indoor work of Baoshan Xunke county ，this paper studied copper，tungsten and m0lybdenum polymetallic deposit，by the analysis of geological characteristic and ore—controlling condition of songping gold deposit，the relationship between copper，tungsten，molybdenum and fracture，rock—body and wallr0ck alteIlati0n I℃vea1ed the geological characteristics about copper，tungsten and molybdenum． By studying the cause of dep0sit and prospecting mark，it will have an direction significance in ore prospecting in this area·
When the exploration line is longer than the prospecting section of High—density electrical survey systerm， use glide prospecting or roll prospecting method to collect data，then inverse with the amalgamation data，the result is 2D section image，contrasting it with the result of single short section prospecting，resistivity anomalies of two methods result is very consistent with chargeability anomalies in the shape and position．Long secion inverse result image call give prominence to high intensity anomaly，and SO on，it come true to contrast all anomalies grade and intensity of the exploration line with two methods．
The wet smelt system technics can distill argentine with nitric acid and distill aurum with aqua fortis in the cyanogens golden mud．But the technics will produce acid gas，it is impo~ant how to deal with the acid gas·This article introduce a way that can absorb the acid gas．And the way can reclaim the acid gas and the aurum in the acid gas，the way can make economy profits and community benefit
Determination of gold in inferior gold potassium of cyaniding by the gravimetric method is economic，simple and practica1．We get the gold by heating the inferior gold potassium of cyaniding in acidic solution，cooling，fihe— ring，washing and weighing，we can calculate the determination of gold in inferior gold potassium of cyaniding．The gravimetric method is be beneficial to elevate the accuracy of analysis results．
