摘要
内蒙古牙克石市喇嘛山有海西期至燕山期白岗质花岗岩岩组和花岗斑岩岩组出露。受新华夏构造体系波及,塑性地层发生褶皱,刚性岩层断裂,形成区内大小28座突兀挺拔、陡峭嶙峋的花岗岩奇峰;又由于该区气候湿润,岩石风化、溶蚀较快,周围岩石脱落,导致各种类型的花岗岩峰石球化,形成大量石蛋、石柱、象形石、石槽、岩臼、石穴等微地貌。文中简述了喇嘛山花岗岩景观的类型、特征,对其成因进行了分析。
Hercynian alkaline granites and the granite-porphyry of Yanshanian period are exposed in mountain Lama,Yakeshi,Inner Mongolia.The New China Tectonic System in some extent lead to folded plastic strata folded and rigid rocks broken in this area,which shaped twenty-eight varying-sized,abrupt,steep rugged,intricate structured granite peaks,and framed a unique granite-peak-landscape inhe Greater Hinggan region.At the same time,owing to in cold and humid climate of this area,rocks regularly fell 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 article summarized the type and characters of the granite landscape in mountain Lama,and analyzed its origin.
