A Critical Analysis of Gold Prospecting Methods

Exploration and prospecting for mineral resources deposits are perceived to not be an easy process due to big deposits being discovered in early times. Numerous gold prospecting methods have been used in gold prospecting. The aim of this research is to critically analyze both traditional and modern gold prospecting methods that are being used in gold exploration. The research objective is to critically evaluate the numerous studies that focus on gold prospecting methods in an effort to provide an effective analysis of gold prospecting methods. In doing so, the study has used a qualitative method to review the existing literature. The study reviews academic journals and articles, books, and periodicals which were published between 2010 and 2019. This study has achieved to critically analyze both traditional and modern gold prospecting methods. The study finds out that the traditional gold prospecting methods include gold panning and dry washing. Additionally, the current gold prospecting methods include biological prospecting, geochemical prospecting and geophysical prospecting methods.

Gold Mineralisation in the Intiédougou Prospect (Diébougou District) in Southwest Burkina Faso, West African Craton

The Intiédougou located in the Houndé Birimian greenstone belt has been the subject of several mining and geoscience studies that have led to the discovery of mineralized gold targets. One of these mineralized targets has prompted work that raises the issue of control factors for the gold mineralization of the prospect. The methodology used in this study combines a study of core drill hole data located in the area and laboratory studies. The Intiédougou sector is based on andesito-basaltic, andesitic interstratified volcanoclastite rocks and Tarkwaïen type detrital sedimentary rocks caught in a vice in the volcano-sedimentary unit. Lithostructural analysis of the sector shows that the subvolcanic rocks bearing gold mineralization are subjected to heterogeneous ductile to brittle deformations and affected by hydrothermalism evolving at stages marked by large fissure fillings. These hydrothermal phases evolve in the zones of expansion created by the brittle deformations that have contributed to the deposits of different types of gold-enriched sulphides. These different phases of hydrothermal destabilization generally of low degree accompany the tardi to post-eburnean brittle tectonics. This deformation system is favorable to the establishment of gold mineralization in the form of vein bodies. The overimposition of deformed and altered areas suggests a genetic relationship between deformation and hydrothermal activity. In conclusion, the mineralization of Intiédougou in vein styles, set up in a volcanic arc environment with a paragenesis of gold-pyrite deposit ± chalcopyrite would be controlled by the structural aspect and accompanied by hydrothermal alteration.

Geophysical-Geological Interpretation and Deep-Seated Gold Deposit Prospecting in Sanshandong-Jiaojia Area, Eastern Shandong Province, China

Integrated gravitational, electrical-magnetic surveys and data processing carried out in the Sanshandao-Jiaojia area, Eastern Shandong Province, northeast China, aim to illuminate the geological characteristics of this shallow-covered area and delineate deep-seated gold prospecting targets. In this region, altogether 12 faults exert critical control on distribution of three types of Early Precambrian metamorphic rock series, i.e. those in the metamorphic rock area, in the granitic rock area underlying the metamorphic rock, and in the remnant metamorphic rock area in granites, respectively. Additionally, the faults have major effects on distribution of four Mesozoic Linglong rock bodies of granite, i.e. the Cangshang, Liangguo, Zhuqiao-Miaojia and Jincheng granites. The Sanshandao and Jiaojia Faults are two well-known regional ore-controlling faults; they have opposite dip direction, and intersect at a depth of 4500 m. Fracture alteration zones have striking geophysical differences relative to the surrounding county rocks. The two faults extend down along dip direction in a gentle wave form, and appear at some steps with different dips. These steps comprise favorable gold prospecting areas, consistent with a step metallogenic model. Six deep-seated gold-prospecting targets are delineated, i.e. Jincheng-Qianchenjia, Xiaoxizhuang-Zhaoxian, Xiyou-Wujiazhuangzi, Xiangyangling-Xinlicun, Panjiawuzi and Miaojia-Pinglidian.

A Prospecting Mineralogy Study: Arsenopyrite In Endogenetic Gold Deposits

Arsenopyrite is one of very important and common auriferous minerals in endogenetic gold deposits. In seven gold deposits, the prospecting typomorphic characteristics of arsenopyrite, such as morphological typomorphism, composition typomorphism, pyroelectricity typomorphism and so on, were established. The crystal form of arsenopyrite is simple, and the form symbols mainly are {101}, {120}, {210}, {140}, {230}, {012}, etc. The smaller grain and poor crystal form arsenopyrite indicates the better auriferous characteristics. The major elements (Fe, As and S) of gold-bearing arsenopyrite usually show Fe/As+S>0.5,As/S<1 which deviates from its theoretical value. The most important trace element is Au and next is Ag in arsenopyrite, and they often show the positive correlation. The pyroelectricity of arsenopyrite can reflect the mineralization epoch, and it also is related to the crystal form and granudarity.

Geological Characteristics and Regional Prospecting Model of Wulanchongji Gold Orebody, Alxa Youqi, Inner Mongolia, China

Five gold deposits (mineralization) were found in the study area by means of geological mapping, soil geochemical survey and trough exploration engineering. The ore-bearing lithology is mainly metamorphic feldspar sandstone of the Upper Carboniferous Benbatu Formation, and the gold (mineralization) body is controlled by both structural factors and stratigraphic factors of the Upper Carboniferous Benbatu Formation. The genetic type is preliminary concluded to be volcanic hydrothermal type, and the metallogenic age is late Variscan. In this paper, by studying the geological characteristics and metallogenic geological conditions of the gold orebody in the area, a regional prospecting model has been established, which is of great significance to better guide the prospecting work of similar gold deposits in the area and the region.

The Kiloton Class Jiaojia Gold Deposit in Eastern Shandong Province and Its Genesis

The recent deep prospecting results in the Jiaojia area of Eastern Shandong Province indicate that the Jiaojia ore field composed of several individual gold deposits as previously suggested is actually an ultra-large gold deposit.This deposit covers an area of ～40 km2,and shows a structural control by the Jiaojia fault and its secondary faults.Gold orebodies generally occur along the same mineralization-alteration belt,and the main orebodies intersect with each other or exhibit a parallel or overlapping distribution.This deposit＇s reserves are estimated to be 1,200t of gold,being the first gold deposit of more than 1000t gold reserves in China.The No.Ⅰ-1 orebody in the Shaling-deep Sizhuang ore blocks holds gold reserves greater than 350 t,or 29 percent of the total reserves,followed by the No.Ⅰ orebody in Matang-Jiaojia ore blocks with exceeding 150t gold reserves.This deposit mainly occurs in the footwall of the Jiaojia fault,and presents zoned patterns in mineralization,alteration and structures.The strongly mineralized zones agree with strongly altered and tectonically fractured zones.These orebodies display strataform-like,veinlike or lenticular shapes,and generally show characteristics of pinching out and reappearing,branching and converging,expanding and shrinking.The orebodies commonly occur along positions where the fault strike changes and in gentle locations with dips changing from steep to gentle.The main orebodies are parallel to the main plane of the orecontrolling fault,and tend to be gentle from the surface to the deep.The orebodies mainly plunge to the southwest,with plunge angle of 45°-606° Orebodies near the main plane of the ore-controlling fault have more gold resource than those away from main fault zone.The slant depth of orebodies is generally larger than the length along its strike direction; orebodies become thick and gold grades become low from the shallow area to the deep area.Ore-forming fluids are H2O-CO2-NaCl±CH4 type with medium-temperature and moderate to low salinity.Sulfur isotopic values （δ34SCDT） for gold ores range between 11.08‰ and 12.58‰,indicating mixed sulfur sources; hydrogen isotopic values （δDVSMOW） range from-83.68‰ to-116.95‰ and oxygen isotopic values （δ18OV-SMOW） range between 12.04‰ and 16.28‰.The hydrogen and oxygen isotopes suggest that ore-forming fluids originated from primary magma,and mixing with a large amount of atmospheric water during the late stage.The Eastern Shandong Province gold deposits are associated with magmatic activities which have mantle crust-mixed source,and also share some similarities with orgenic and epithermal hydrothermal golddeposits.Because Eastern Shandong Province gold deposits with unique metailogenic features and formation setting which are different from other gold deposit types in the world,we call it the Jiaojiatype gold deposits.The kiloton class Jiaojia gold deposit is related to fluid activities,extension and detachment resulted from thermal upweiling of magmas.The strong magmatic activities in the middle to late stage of early Cretaceous in Eastern Shandong Province lead to active fluids,and provided abundant ore-forming materials for gold depsoits.Moreover,many extensional structures resulting from crustal extension provided favourable space for orebody positioning.

东北地区金矿成矿规律及找矿方向

金矿是一种重要的贵金属矿产,也是东北地区优势矿产之一。东北地区金矿资源丰富,分布具有明显的区域性集中趋势,是我国岩金尤其是砂金的重要产区。本文系统收集和整理了已有东北地区金矿地质资料,全面总结了东北地区金矿资源禀赋、矿床类型、时空分布规律、成矿演化,指出了进一步的找矿方向。综合金矿床的工业类型和成因类型,将东北地区金矿床分为砂矿型、岩浆热液型、陆相火山岩型、变成型和受变质型、斑岩型、叠加型及成因暂时未查明的流体型等类型。岩金主要分布于华北成矿省辽东成矿带、华北陆块北缘东段成矿带,吉黑成矿省小兴安岭—张广才岭成矿带、吉中—延边成矿带,大兴安岭成矿省东乌珠穆沁旗—嫩江成矿带等;而砂金主要分布于黑龙江省三江沿岸,大兴安岭成矿省东乌珠穆沁旗—嫩江成矿带、吉黑成矿省佳木斯—兴凯成矿带、小兴安岭—张广才岭成矿带等。东北金矿具有多旋回、多期次成矿的特点,按其规律可划为太古宙、元古宙、加里东期、华力西期、印支期、燕山期、喜马拉雅期等7个成矿期。划分了13个成矿系列,22个成矿亚系列,22个三级预测区,显示出良好的成矿条件和找矿前景。

贵州普克金矿区黄铁矿和方解石地球化学特征及地质意义

贵州普克金矿区位于我国著名的滇-黔-桂“金三角”地区泥堡大型金矿西南方向的外围区域,与泥堡金矿处于相同的大地构造环境,地层特征、构造样式基本相同,成矿地质条件良好,对其开展成矿流体性质和物质来源研究,有助于理解普克矿区金的成矿作用,并为下一步找矿勘探提供新的参考。本文在对普克金矿区地表发育的(褐铁矿化)黄铁矿-方解石脉进行野外地质调查的基础上,开展矿物学、方解石稀土元素以及黄铁矿电子探针与微区原位LA-ICP-MS分析,结果显示普克金矿区内大部分方解石脉显示出与泥堡金矿床不含矿方解石脉相似的稀土元素配分特征,少数方解石样品显示出与黔西南卡林型金矿成矿期方解石稀土元素一样的中稀土元素富集和Eu正异常特征。该类方解石脉中的黄铁矿Au元素含量高出平均地壳丰度及沉积成因黄铁矿中Au的含量几个数量级,且Au在黄铁矿中以Au+离子形式存在,表明这些黄铁矿形成于金成矿期的热液环境。含金方解石出现中稀土元素富集模式和Eu正异常特征,表明金成矿流体系还原性质。由于地壳抬升剥蚀的影响,普克金矿区内中稀土元素富集、Eu正异常的方解石脉在地表的露头较少,也可能与普克金矿有利成矿地层层位(二叠系峨眉山玄武岩组)埋深较大、能运移到现今地表层位(三叠系永宁镇组)的成矿热液相对较少有关,指示深部有较好的金成矿潜力。

大兴安岭中生代火山盆地是区域上寻找浅成低温火山热液型金矿床的有利区,前人在大杨树火山盆地西缘开展1∶5万矿产调查时,已圈定出张点和扎罗梅2处远景区。利用零星的槽探工程开展物化探异常验证:在张点矿区发现1条稳定延伸的含金石英脉,长约0.95 km,视厚度为5~15 m,最高金品位为88.25×10^(-6);在扎罗梅矿区发现2条金矿体、1条金矿化体、1条银矿体,其中I号和II号金矿体被推断为同一条金矿体,长度大于600 m,视厚度为2~3 m,最高金品位为5.83×10^(-6),IV号银矿体视厚度为4.0 m,最高品位为(50.90~310.00)×10^(-6)。综合分析两个矿区的土壤化探异常和激电中梯测量视极化率异常特征,并与区域上三道湾子等金矿床的成矿地质条件进行对比,认为张点和扎罗梅矿区的金矿点具有中—大型成矿资源潜力。大杨树火山盆地边缘金矿点的发现可为大兴安岭火山岩带的金矿勘查部署提供参考,促进勘查及研究程度的提高,有助于实现找矿突破。

胶东金矿与中生代区域性花岗岩关系及成矿预测和找矿方向

胶东地区是世界著名的金矿资源基地,截至2023年6月已累计探明金矿资源量已达5757余吨。与金矿成矿密切的中生代花岗岩分布广泛,岩石类型多样,也是山东省最发育、最典型的地区。本文对胶东地区金矿与中生代区域性花岗岩空间展布、形成时代和形成环境等关系进行了分析研究。区域性广泛分布的中生代花岗岩为晚侏罗世玲珑期(166~146 Ma)、早白垩世早期郭家岭期(135~123 Ma)、早白垩世晚期伟德山期(123~110 Ma)和崂山期(118~108 Ma),研究认为区域性岩浆事件一般持续10 Ma左右,而重熔型花岗岩一般持续20 Ma,反映了由基底岩石熔融到侵入结晶的2个阶段,它有一个由基底固体岩石熔融的过程,大致也需要10 Ma,既固体岩石熔融10 Ma,熔浆活动上侵结晶10 Ma。玲珑期重熔型花岗岩是扬子板块和华北板块碰撞的期后产物,郭家岭期岩浆事件代表了中国东部中生代构造体制转换的开始,伟德山期岩浆事件代表了构造体制转换的高峰期,崂山期岩浆事件代表了构造体制转换的结束期。86.8%的金矿赋存在玲珑期花岗岩中,6.9%的金矿赋存于郭家岭期花岗岩中,玲珑期花岗岩和郭家岭期花岗岩Au元素背景值明显高于伟德山期花岗岩和崂山期花岗岩。矿石硫与玲珑期花岗岩、郭家岭期花岗岩范围相近,特别是与玲珑期花岗岩大范围重叠,具有岩浆热液硫同位素变化小的特点,说明矿石硫主要源为玲珑期花岗岩、郭家岭期花岗岩。矿石铅主要为再活化的下地壳铅,即前寒武纪结晶基底铅,有幔源铅加入。金矿成矿年龄有162~146 Ma、133~120 Ma、120~115 Ma、112~105 Ma共4个区间范围,与胶东地区四期区域性花岗岩形成时间对应,成矿年龄一般晚于成岩年龄3~5 Ma。根据胶东金矿及多金属矿与岩浆热液事件对应关系,划分为玲珑金成矿期、郭家岭金成矿期、伟德山金及多金属成矿期和崂山多金属成矿期。胶东地区金矿主要是新太古代变质地层和古元古代底部片岩层位经过重熔作用金元素活化、迁移、富集和郭家岭期岩浆作用成矿。基于以上成矿作用认识,根据地球化学块体理论,对胶东金矿潜力进行了估算,胶东地区3000 m以浅金矿潜力约为1.8万t,同时对胶西北深部金矿进行了系统预测,预测3000 m以浅金资源量3997 t,5000 m以浅7497 t。通过地质综合研究,栖霞地区中新太古代变质岩下部有隐伏玲珑期花岗岩,根据金矿主要赋存在玲珑期花岗岩中的空间展布,S、Pb等同位素以及玲珑期花岗岩是金矿成矿直接围岩或母岩的认识,该地区变质岩中发育众多的石英脉型中小型金矿和矿(化)点,可能是浅部或顶部矿体的表现,认为该地区具有良好的成矿背景和潜力,是胶东地区今后金矿找矿的重要地区和方向。并建议在该地区部署地震和大功率激电剖面及地质科研钻探,查清一系列NE向断裂和地质结构,为金矿找矿提供科学依据。

胶东西岭金矿床黄铁矿热电性特征及深部找矿意义

西岭金矿床位于三山岛金矿床东侧,是当前胶东金矿集区内新发现的单一矿体规模最大、埋藏最深的金矿床。在地质观察的基础上,开展了不同深度的黄铁矿热电性特征研究。结果表明:西岭金矿床黄铁矿热电系数离散范围和离散度整体较大且相对稳定;浅部黄铁矿热电导型均为N型,而深部均为P型;成矿温度主要集中在250~360℃之间,属中—高温热液型金矿床;计算得出黄铁矿热电导型变化梯度值较小,并估算出矿体剥蚀率约为75%。综合黄铁矿各类热电性特征参数,认为西岭金矿床深部仍有较大的找矿前景,矿体最大埋深可达-3000 m标高。已知金矿体具有向NE侧伏的规律,认为沿着NE侧伏方向至-3000 m标高处是有效的深部找矿靶区位置。西岭金矿床黄铁矿热电性特征研究可为胶东地区金矿床的深部找矿预测提供科学依据。

辽宁新房金矿床原生晕地球化学特征及对深部找矿的指示

辽东半岛南部的新房金矿床由22、23、24、25、27号5条矿脉带组成,矿区内主要矿体已被发现,提能增储成为制约矿山持续服务的因素,矿床勘查过程中的钻探工程部署迫切需要科学、有效的成矿预测依据。以新房金矿床106线14个钻孔原生晕数据为研究对象,研究地球化学特征和元素分带规律,建立轴向分带序列,在研究原生晕地球化学特征基础上开展深部找矿预测。结果表明,新房金矿的前缘晕元素为As、Sb、Hg,近矿晕元素为Au、Ag、Cu、Pb、Zn,尾晕元素为W、Mo、Bi。采用分带指数法计算了22、23、24、25、27号5条矿脉带的轴向分带序列,指示5条矿脉带均出现“反分带”现象,可能是不同矿化阶段的矿体在空间上叠加导致正常的轴向分带序列出现错位。22、23、24、27号矿脉带的中下部出现较强的前缘晕和近矿晕,结合地球化学参数特征,这4条矿脉带的As/W、As/Mo、Sb/W、(As×Sb)/(Mo×W)评价指标出现多次振荡波动,并且在深部由降转升,指示深部有较好的找矿潜力。综合以上分析认为,新房金矿床经历多次成矿热液活动,在106勘探线东侧矿体还有一定的延伸。
