摘要
我国地域辽阔,碳酸盐岩出露广泛,在不同的地质构造、地形、气候及生态环境条件下发育有多种类型的岩溶。本文所论及的岷山地区的岩溶,实际上是一种在高山地形气候条件下发育的高寒岩溶亚类。从事物发展的系统观出发,作者认为岷山型岩溶是一高山峡谷岩溶系统,在垂向空间上,可区分为山岳高寒岩溶和峡谷温带岩溶两个不同层次。文中阐述了它们各自的基本特征、相互关系及其形成条件。关于岷山岩溶的一个重要特征—泉钙华沉积,将在“岷山岩溶的灰华沉积”一文中讨论。
China is a vast country with extensively exposed carbonate rocks. Various types of karst developed under different conditions of geological structures, landforms, climates & ecologic environments. Karst in Minshan Mt. area,being expounded in the paper, is in fact a subtype of paramos karst which is developed under the condition of topography and climate of Alps. The authors, from the systematic viewpoint of material evolution, considered that the 'Minshan Mt. -type karst' as a high mountain-gorge karst system constituted vertically by two different subsystems: the upper zone of mountain paramos karst and the lower zone of gorge temperate karst, The basic features and the correlation of these two subsystems and specific conditions under which they are formed and developed are discussed as well. As for the deposition of sinter, being an important feature of Minshan Mt.-type karst, will be discussed in another paper entitled 'Sinter deposits of Minshan Mt. karst' .
