山东省花岗岩地貌景观的构造分区和典型类型研究

山东地处中国大陆地壳一级构造区华北板块的东南缘,构造作用和岩浆作用,特别是新太古代和中生代的花岗质岩浆作用十分强烈,形成了大量的花岗岩类,构成山东省各类花岗岩地貌景观的物质基础。以山东省重要地质遗迹调查成果为基础,开展深入分析总结,结合山东花岗岩分布格局,划分为华北板块鲁西隆起区、胶辽隆起区和苏鲁造山带胶南-威海隆起区3个不同花岗岩地貌景观分区;从造型和观赏的角度将山东省花岗岩地貌又划分为峰丛型、峰林型、山丘型、石蛋型和岩穴型花岗岩地貌景观5类,并以泰山、蒙山、五莲-九仙山、莲青山、峄山等典型实例,论述了各类花岗岩地貌景观特征,并对其形成过程进行了探讨,同时也论述了影响花岗岩造型景观的主要内部和外部因素。

Study on the Structural Division and Typical Types of Granite Landscape in Shandong Province

Shandong province is located in the southeast margin of the North China plate in the first tectonic zone of the mainland of China. The tectonic action and magmatism, especially Neoarchean and Mesozoic granitic magmatism is very strong, and formed a large number of granites. It has formed the material basis for various granite geomorphology in Shandong province. Based on survey results of important geological relics in Shandong province, combining with the distribution pattern of granites, three different granite landscape zones have been divided, they are Luxi uplift area of the North China plate, Jiaoliao uplift area and uplift area of Sulu orogenic belt. From the view of modeling and viewing, the granite landforms in Shandong province can be divided into five categories, they are peak cluster type, peak forest type, hilly type, stone egg type, and cavetype granite topography landscape. Taking Taishan Mountain, Mengshan Mountain, Wulian Jiuxianshan Mountain, Lianqingshan Mountain, Yishan Mountain as typical examples, the characteristics of landscape of various types of granite and the formation process have been discussed. At the same time, main internal and external factors affecting the granite landscape have been studied as well.
