【摘要】：本論文以中國地質(zhì)調(diào)查局《花崗巖地質(zhì)遺跡分類與成因研究》項目為依托,以華山花崗巖地質(zhì)遺跡為研究對象,系統(tǒng)地調(diào)查了華山花崗巖地質(zhì)遺跡的分布狀況和類型特征;探討了華山花崗巖地質(zhì)遺跡景觀的成因機(jī)制、演化過程及成因分類;基于花崗巖地質(zhì)遺跡脆弱模式的解析,對華山花崗巖地質(zhì)遺跡景觀的脆弱性進(jìn)行了分類分級評價,為花崗巖地質(zhì)遺跡景觀的成因及脆弱性研究提供了示范。其主要創(chuàng)新性成果如下:(1)在前人區(qū)調(diào)成果的基礎(chǔ)上,編制出有特色的華山景區(qū)的地質(zhì)—構(gòu)造簡圖,深化了對太華雜巖的認(rèn)識;采用構(gòu)造解析的方法將景區(qū)劃分為太華群、太古代片麻巖巖套和花崗巖為主的三個構(gòu)造區(qū),特別是對華山花崗巖中的構(gòu)造類型的確定,提升了華山景區(qū)基礎(chǔ)地質(zhì)研究的認(rèn)知水平;(2)系統(tǒng)查明了華山花崗巖地質(zhì)遺跡的空間分布格局,揭示了不同類別地質(zhì)遺跡的地質(zhì)屬性;提出將華山花崗巖地質(zhì)遺跡景觀分成山景、峰景、谷景、單景等4個層次和類型,并細(xì)分出山景、峰景、谷景和單景的多個亞類;據(jù)此,對華山地質(zhì)遺跡的發(fā)育特征和分布規(guī)律進(jìn)行系統(tǒng)分析,首次確立了華山花崗巖地質(zhì)遺跡景觀“四層次”體系;(3)首次提出了 巖漿動力孕景、構(gòu)造動力造景、地表營力成景和人類活動潤景‖的四層次動力驅(qū)動花崗巖地質(zhì)遺跡景觀形成的新觀點(diǎn),從本質(zhì)上闡明了華山花崗巖地質(zhì)遺跡的內(nèi)外動力成景機(jī)制,并再現(xiàn)了“巖體侵入孕育、抬升出露地表、群峰河谷出現(xiàn)、景觀發(fā)展優(yōu)化”的華山花崗巖景觀形成演化的4個階段演化過程,并在此基礎(chǔ)上提出了華山花崗巖地質(zhì)遺跡成因分類方案;(4)依據(jù)華山花崗巖地質(zhì)遺跡景觀的賦存環(huán)境、發(fā)育特征、影響因素、成因機(jī)制和演化階段等要素,闡明了華山花崗巖地質(zhì)遺跡景觀的脆弱性模式,建立了其評價指標(biāo)體系,對華山花崗巖地質(zhì)遺跡的脆弱性進(jìn)行了分類分級評價,為地質(zhì)遺跡景觀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.
