    摘要:

    在生物地球化学和“深穿透”理论的指导下,在兰坪-思茅盆地勐野井钾盐矿区及周边开展了生物地球化学找钾技术方法的探索性研究。沿江城县勐野井钾盐矿区及周边一线,对乔木类植物叶子进行了取样,分析,数据处理,特征指标筛选,获得了研究区植物样品主量和微量组分含量背景值,初步圈定了异常区,与以往圈定的找钾远景区较吻合。该区生物地球化学找钾技术取得较好的效果,今后还需扩大采样区域,获得更多样本数据,将找钾特征指标及其异常值的阈值进一步补充完善。

    Abstract:

    The Mengyejing potash deposit in Yunnan Province is till now the only solid potash deposit discovered in China. Inspired by the theory of "deep penetration" and biogeochemistry, a biogeochemical method is preliminarily studied for potassium prospecting in the Mengyejing deposit area and its surrounding areas. A total of 71 plant samples (leaves of tall trees) were collected from the research areas. Over complicated sample preparation (including washing, air-drying, grinding, screening, chemical digesting), determining, data processing and analyzing, the background values of major and trace components for plant samples were obtained, and meanwhile the anomaly areas were preliminarily delineated, which are in good agreement with the prospect areas delineated in former studies. Further sampling and more research work need to be carried on in order to offer more useful data and techniques for potassium prospecting, as well as other ore deposit prospecting.
