汞作为赋金属矿化探途的应用已成为一种澳大利亚矿例研究加以调查,该科研项目的主要目标为:(1)比较汞的性状,参照多变的气候和地貌条件下出露贱金属矿体附近汞异常的强度和范围,用它来做次生环境下的靶元素:(2)测定蒸气生成的汞异常是否可探测埋藏矿和盲矿的地表介质,如果可能的话,应在哪些地质、地貌和气候条件下;(3)用汞量测量法来确定最合适的取样介质和方法;(4)为地质样品中测定汞以发展合适的技术。本项目共完成29个矿例研究任务,包括一系列矿化类型和矿种,它们是在各种次生状态下产出的。上述研究所得资料与实验室和理论思考一道,可导致下列作为勘探贱金属矿床的汞地球化学及其可能起作用的结论:(1)汞在许多矿化类型中显现足够的浓度,可用作潜在探途元素;变质作用并未使之大量逸失。(2)汞倾向赋予:“剩余”异常以微小可察觉的次生分散现象,已确定那里汞是一种有效的探途元素。然而,在一般勘探中汞没有优于Cu、pb、zn等靶元素的有利条件。(3)在某些条件下,汞可能指示埋藏的矿体。(4)气相取样的用途仅适于相当专门的环境;土壤几乎总是优选的样品介质。(5)汞量测量法可在常规状态下以背景含量进行测定,如果能遵守某些必要条件的话。致于肓矿体,剩下的问题是需要进一步试验,因为大部分研究区显示地球化学反映。
The use of mercury as a metallogenic excursion has become an Australian case study to investigate the main objectives of this research project: (1) to compare mercury traits with reference to changing climates and geomorphological conditions exposing base metals The intensity and range of mercury anomalies near the ore body, which are used as target elements in the secondary environment: (2) Determination of mercury anomalies generated by steam Whether the surface media of burial mines and blind mines can be detected, if possible, which Geology, geomorphology and climatic conditions; (3) Determination of the most appropriate sampling media and methods using mercury measurements; and (4) Determination of mercury in geological samples to develop appropriate techniques. A total of 29 mine-case research missions were completed, including a series of mineralization types and minerals, which were produced under various secondary conditions. The data from these studies, together with laboratory and theoretical considerations, can lead to the following mercury geochemistry as exploratory base metal deposits and their possible conclusion: (1) Mercury appears in sufficient concentrations in many mineralization types and can be used as Potential exploration elements; metamorphism did not make a lot of escape. (2) Mercury propensity confers: “residual” anomalies with minor, detectable secondary dispersal, where it has been determined that mercury is an effective excursion. However, mercury does not have favorable conditions for target elements such as Cu, Pb and Zn in general exploration. (3) Mercury may indicate buried ore bodies under certain conditions. (4) The use of gas sampling is only suitable for a fairly specialized environment; the soil is almost always the preferred sample medium. (5) The mercury measurement method can be measured in the background under normal conditions, if certain requirements are complied with. To 肓 ore bodies, the remaining problem is the need for further testing, as most of the studied areas show geochemical reflectance.
