| 中文摘要: |
| 本文通过赣东北三个不同矿化类型矿床,进行的矿物地球化学找矿法研究,阐明该方法找矿的效果。研究表明,黄铁矿对成矿元素和伴生元素有显着的富集作用;选用黄铁矿样品进行矿物地球化学测量,能发现矿床周围岩石中微弱的矿化异常。黄铁矿中元素含量的变化又与成矿作用的过程有关,利用黄铁矿与岩石中元素浓度比的变化,能指示矿化作用的趋向与矿体分布的位置。因此矿物地球化学找矿法,是一种新的有效找矿方法。 |
| 英文摘要: |
| Based on study of three types metal deposits in metallogenic belt of north-eastern Jiangxi province, we try to demonstrate the effect of geochemical mineral surveys. The results was shown that the pyrite in wallrock can enrich greatly the ore-forming and accessory elements. When geochemical mineral surveys was made, the samples of pyrite can help us to find the weak mineralization in the wallrock. Now that variation of the contents of elements in the pyrite correlates with process of mineralization, change of concentration ratio ratio between pyrite and rock will display the tendency of mineralization and the site of deposit. Therefore the geochemical surveys is a new method of geochemical surveys which is effective. |
