Abstract

Shizhuyuan is a world-class W-Sn supergiant polymetallic deposit, with a large area of potential mineralization around it. Dicranopteris dichotoma, widely distributed in the Shizhuyuan mining area, were sampled. Biogeochemical and Number-Size fractal methods were used to evaluate the biogeochemical characteristics of trace elements in the samples and the feasibility of indicating subsurface mineral deposits. The results reveal that D. dichotoma not only has strong uptake of the active state of metal elements (Zn, Mo, Cd, Sn, etc.) in the soil, but also shows the geochemical anomalies of Zn, Fe, Tl, Ag, Pb, U, As, Bi, Cd, Mo and Sn in the study area. The Number-Size fractal method can effectively identify the concentration populations of biogeochemical target elements and obtain convincing anomaly thresholds. Analysis of the metal content of D. dichotoma is an effective tool for biogeochemical exploration of Pb-Zn-U hydrothermal deposits in the study area. Zinc as well as U are target elements, and Tl appears to be an effective pathfinder element for Zn-Pb-U mineralization. In addition, 260-340 m of Line 3 # and 1100-1200 m of Line 8 # are the key areas for future exploration of lead-zinc-uranium hydrothermal deposits.

十竹园多金属矿区微量元素生物地球化学分形特征及其找矿意义

石竹园是一个世界级的钨锡超巨型多金属矿床，其周围具有大面积的潜在成矿作用。对广泛分布于石竹园矿区的Dicranopteris dichotoma进行了取样。采用生物地球化学和Number-Size分形方法评价了样品中微量元素的生物地球化学特征和指示地下矿床的可行性。结果表明，D. dichotoma不仅对土壤中金属元素(Zn、Mo、Cd、Sn等)的活性态具有较强的吸收能力，而且在研究区表现出Zn、Fe、Tl、Ag、Pb、U、As、Bi、Cd、Mo、Sn等地球化学异常。Number-Size分形方法能有效识别生物地球化学目标元素的浓度种群，获得令人信服的异常阈值。D. dichotoma金属含量分析是研究区铅锌铀热液矿床生物地球化学勘查的有效工具。锌和U是靶元素，而Tl是锌-铅-U成矿的有效探路者元素。另外，3 #线260 ~ 340 m和8 #线1100 ~ 1200 m是今后铅锌铀热液矿床勘探的重点区域。

期刊介绍： Geochemistry: Exploration, Environment, Analysis (GEEA) is a co-owned journal of the Geological Society of London and the Association of Applied Geochemists (AAG). GEEA focuses on mineral exploration using geochemistry; related fields also covered include geoanalysis, the development of methods and techniques used to analyse geochemical materials such as rocks, soils, sediments, waters and vegetation, and environmental issues associated with mining and source apportionment. GEEA is well-known for its thematic sets on hot topics and regularly publishes papers from the biennial International Applied Geochemistry Symposium (IAGS). Papers that seek to integrate geological, geochemical and geophysical methods of exploration are particularly welcome, as are those that concern geochemical mapping and those that comprise case histories. Given the many links between exploration and environmental geochemistry, the journal encourages the exchange of concepts and data; in particular, to differentiate various sources of elements. GEEA publishes research articles; discussion papers; book reviews; editorial content and thematic sets.
