Characteristics and Origin Analysis of the Granite Landscape of the Lama Mountain in Yakeshi, Inner Mongolia
内蒙古牙克石喇嘛山花岗岩景观特征及其对比分析

Hercynian alkaline granites and Yanshanian granite-porphyry are exposed in the Lama Mountain of Yakeshi City, Inner Mongolia. The influence of the Neocathaysian tectonic system led to the folding of the plastic strata and the faulting of the rigid strata in this area, which resulted in the formation of twenty-eight varying-sized, abrupt, steeply rugged, intricately structured granite peaks and the generation of a unique granite-peak-landscape in the Da Hinggan Ling. At the same time, owing to the cold and humid climate of this area, rocks tended to fall off by such external forces as water erosion and freeze-thaw weathering, forming a large number of realistic and vivid pictographic stones, pillars, niches and rock erosion mortar landscapes. This paper has summarized the type and characteristics of the granite landscape in the Lama Mountain, and compared the features of granitic geomorphologic landscape in the Lama Mountain with those in other areas.
