【摘要】：本文就地质空间混成性研究中的地质体数字频谱模型展开探讨,首先对地质空间进行探索性的定义并讨论其基本性质;针对地质空间分布与变异性的这一科学本质问题进行了阐述,在地质空间三相结构分类准则指导下,以地质体为基本单元,讨论大数据数字频谱模型的原理。本文是以鄂尔多斯砂岩型铀矿资源潜力评价中的铀矿组合异常分析作为研究对象,在具体研究对象选择上,考虑到论文内容与课题任务之间的隶属关系,因此选择鄂尔多斯盆地内大营铀矿区钻孔测井数据及盆地北缘区域地球化学测量数据作为应用案例的数据支撑,进行地质大数据融合分析以构建大样本综合标度,再结合区域地质资料及前人研究成果,探讨地质空间数字频谱理论方法的改进及具体应用问题,建立反映盆地外围地球化学亲铀元素组合因子分布与变异规律的频谱模型和反映盆地内铀矿化组合异常的频谱模型,并对案例计算结果进行分析解释,为盆地外围基于地球化学观测数据的含铀母岩系供铀能力分析和盆地内基于钻孔测井数据的地质异常聚铀能力分析提供定量依据;最终为建立砂岩型铀矿资源潜力评价体系提供一种尝试性的基础研究方法。
[Abstract]:This paper discusses the geological body model of digital spectrum study on the hybrid geological space, firstly geological spatial exploratory definition and its basic properties are discussed; according to the geological spatial distribution and variability of the scientific nature of the problem is discussed, in the classification criteria of geological space three phase structure under the guidance of the geological body the basic unit, discuss the principle of big data digital spectrum model. This paper is to evaluate the Erdos sandstone type uranium resources potential in uranium anomaly analysis as the research object, the specific research object selection, taking into account the affiliation between the content and task, so the choice of Erdos basin drilling logging data and the basin uranium mine in northern Da Ying regional geochemical survey data as the application case data support in the construction of large sample, comprehensive scale fusion analysis of geological data, combined with regional geological data and former research results, discusses the improvement of geological spatial digital spectrum theory and application, established to reflect the spectrum model of peripheral basin geochemical Pro uranium combination factor distribution and variation in the basin and reflect the combination of uranium mineralization the spectrum model of anomalies, and the case calculation results are analyzed and explained, as the peripheral basin based on earth It provides quantitative basis for uranium bearing capacity analysis of uranium bearing parent rock series and analysis of uranium anomaly ability based on borehole logging data and finally provides a tentative basic research method for establishing sandstone type uranium resource potential evaluation system.
