| 摘 要： | 覆盖区遥感隐伏地质信息的解译一直是遥感地质工作中难以解决的问题。本文主要讨论如何运用遥感数据处理技术结合各种资料综合分析的方法,提取覆盖区隐伏地质层体信息。通过遥感影像信息、透视信息①、地貌特征信息及水系格式信息等的综合解译,对覆盖层本身的影像信息及反映被覆盖的地质层体的遥感信息进行了研究区分,成功地解译了覆盖区与铀矿化有关的各种隐伏控矿因素的遥感信息。现以伊犁盆地为例,通过解译及综合分析,详细阐述如何解译覆盖区隐伏的控制铀矿分布的产铀建造;圈定了影响产铀建造产出条件及矿化富集条件的隆起和凹陷;同时对控制盆地形成和改造的断裂构造及影响铀成矿作用的相对稳定和相对活动区进行了分析。实践表明,遥感方法不仅对揭示该覆盖区的铀矿分布规律有意义,而且对指导该区进一步铀矿普查与找矿也是有意义的。

| Abstract: | UPto now, the interpretation of remote sensing concealed geology informa- tion in Quaternary covering area is still a tough problem to be solved in remote sensing geology. This paper is aimed at discussing how to utilize satellite image processing method combining with multiple information interpretation to extra- ct useful geological information covered by heavy Quaternary sediment. By means of comprehensive interpretation of image signature, "prospective information", geomorphic features and drainage pattern, we can successfully differentiate the image features between the covering strata and the buried terraine and ascertain ore-controlling factors. Taking the Yili basin for example, the faults(including the buried faults), which control formation and development of the basin,have been interpreted. The Productive uranium formations,which dominate uranium distribution,have been delineated. The uplift and subsidence, which are related to sedimentary environment, have been discriminated. The stable area and active block, which are connected with uranium concentration and preservation, have been discerned. The results have proven to be useful, for revealing the distribution regularities、guiding uranium reconnaissance and exploration further in the covering area. |
