【摘要】：本论文以中国地质调查局《花岗岩地质遗迹分类与成因研究》项目为依托,以华山花岗岩地质遗迹为研究对象,系统地调查了华山花岗岩地质遗迹的分布状况和类型特征;探讨了华山花岗岩地质遗迹景观的成因机制、演化过程及成因分类;基于花岗岩地质遗迹脆弱模式的解析,对华山花岗岩地质遗迹景观的脆弱性进行了分类分级评价,为花岗岩地质遗迹景观的成因及脆弱性研究提供了示范。其主要创新性成果如下:(1)在前人区调成果的基础上,编制出有特色的华山景区的地质—构造简图,深化了对太华杂岩的认识;采用构造解析的方法将景区划分为太华群、太古代片麻岩岩套和花岗岩为主的三个构造区,特别是对华山花岗岩中的构造类型的确定,提升了华山景区基础地质研究的认知水平;(2)系统查明了华山花岗岩地质遗迹的空间分布格局,揭示了不同类别地质遗迹的地质属性;提出将华山花岗岩地质遗迹景观分成山景、峰景、谷景、单景等4个层次和类型,并细分出山景、峰景、谷景和单景的多个亚类;据此,对华山地质遗迹的发育特征和分布规律进行系统分析,首次确立了华山花岗岩地质遗迹景观“四层次”体系;(3)首次提出了 岩浆动力孕景、构造动力造景、地表营力成景和人类活动润景‖的四层次动力驱动花岗岩地质遗迹景观形成的新观点,从本质上阐明了华山花岗岩地质遗迹的内外动力成景机制,并再现了“岩体侵入孕育、抬升出露地表、群峰河谷出现、景观发展优化”的华山花岗岩景观形成演化的4个阶段演化过程,并在此基础上提出了华山花岗岩地质遗迹成因分类方案;(4)依据华山花岗岩地质遗迹景观的赋存环境、发育特征、影响因素、成因机制和演化阶段等要素,阐明了华山花岗岩地质遗迹景观的脆弱性模式,建立了其评价指标体系,对华山花岗岩地质遗迹的脆弱性进行了分类分级评价,为地质遗迹景观的脆弱性研究提供了范例。
[Abstract]:Based on the project of "Classification and Genesis of Granite Geological relics" of China Geological Survey, this paper systematically investigated the distribution and type characteristics of the granite geological relics in Huashan, China, taking the granite geological relics of Huashan as the research object. The genetic mechanism, evolution process and genetic classification of the geological relics landscape of Huashan granite are discussed. Based on the analysis of the fragile model of granite geological relic, the vulnerability of granite remains landscape in Huashan is evaluated by classification and classification, which provides a demonstration for the study of the genesis and vulnerability of granite geological relic landscape. The main innovative achievements are as follows: (1) based on the results of previous regional surveys, the geological-structural schematic map of Huashan scenic spot with characteristics has been compiled, which has deepened the understanding of Taihua complex; The scenic area is divided into three tectonic areas, Taihua Group, Archean gneiss suite and granite, especially the structural type of Huashan granite. The cognitive level of basic geological research in Huashan Scenic area has been improved. (2) the spatial distribution pattern of the geological relics of the Huashan granite has been systematically ascertained, and the geological properties of the different types of geological relics have been revealed. It is proposed that the granite geological relic landscape of Huashan can be divided into four levels and types: mountain view, peak view, valley view and single view, and subdivided into several subtypes of mountain view, peak view, valley view and single view. On the basis of this, the development characteristics and distribution law of the geological relics of Huashan are systematically analyzed, and the "four levels" system of geological relics landscape of Huashan granite is established for the first time. (3) for the first time, a new viewpoint on the formation of granite geological relic landscape driven by the four levels of magmatic dynamic setting, tectonic dynamic landscape, surface Yinglicheng landscape and human activity Runjing is put forward for the first time. In essence, the internal and external dynamic landscape mechanism of the geological relics of the Huashan granite is elucidated, and the "intrusive inoculation of the rock mass, uplift of the rock mass and emergence of the valley of peaks and valleys" are reappeared. Based on the four stages of the evolution of the Huashan granite landscape, a genetic classification scheme for the geological relics of the Huashan granite is put forward. (4) according to the occurrence environment, developmental characteristics, influencing factors, genetic mechanism and evolution stage of the granite geological relic landscape in Huashan, the vulnerability model of the geological relic landscape in Huashan granite is expounded, and its evaluation index system is established. The vulnerability of granite in Huashan is evaluated by classification and classification, which provides an example for the study of vulnerability of geological relic landscape.
