| 中文摘要: |
| 通过对大葫芦山一带的地球化学特征、化探异常分布及异常特征的研究表明,岩石风化及元素迁移方式、风成沙干扰,对研究区水系沉积物中微量元素特征影响强烈;各地层单元及岩浆岩体构成不同的成矿地球化学环境。研究区发育3个具不同元素组合的综合异常,可分为受地层-构造共同控制的和受花岗质岩石控制的2类异常,反映出不同的成矿作用、矿化空间、分布规律及找矿意义。 |
| 英文摘要: |
| Geochemical characteristics, distribution of geochemical anomlies and the characteristics of the geochemical anomalies suggest that rock weathering and migration pattern of elements, aeolian sand have heavy influencee on micro-element distribution of river sediments. Each stratigraphic unit and magmatic body constitutes different ore-forming geochemical settings. In the working area are developed 3 synthetic anomlies with different element associations and the anomlies are divided into 2 types, i.e. the anomly controlled by both stratum and structure and the other by granitoids. The anomlies are varied in metallogenesis, mineralization space and significance for ore prospecing.. |
