摘 要黄山地区出露岩石以花岗岩为主，本文通过对黄山地区典型花岗岩地貌景观的观察描述，了解该区区域地质概况及所处断裂带与地貌演变等基本信息，重点对断裂构造进行描述，并对测区内节理进行了应力场分析，以此得出黄山复式岩体根据其接触关系、各期次岩石的矿物学及岩石学特点可划分为四个期次：第一期为中粒碱长花岗岩；二期为中粗粒似斑状碱长花岗岩；第三期为中细粒斑状碱长花岗岩；第四期为细粒含斑碱长花岗岩。同时，构造是如今黄山地区地貌景观形成的主要因素，以节理和断裂最为显著。其中汤口断裂、北西向断裂组合、汤岭关断裂对花岗岩地貌的成型起重要作用，而节理作用则是岩峰与怪石的主要成因，一定程度上也影响着岩洞的发育。关键词：黄山 花岗岩 构造IABSTRACT Huangshan area exposed rocks mainly granite, in this paper, through the observation of the Huangshan area typical granite landscape description, understand the fault zone and geomorphic evolution of regional geological survey and by use of the basic information, such as focusing on fracture structure is described, and the stress field analysis on joint test areas, to come to Huangshan compound rock mass according to the contact relationships, the issue of mineralogy and petrology characteristics of rocks can be divided into four periods: The first stage is medium grain alkali granite. The second stage is medium coarse grained porphyritic alkali granite. The third stage was medium - fine - grained porphyritic alkali granite. The fourth stage is the fine-grained porphyritic alkali-bearing granite. In addition, structure is the main factor for the formation of the landscape in Huangshan area, especially the joints and faults. Among them, the tongkou fault, the nw fault association and the tanglingguan fault play an important role in the formation of granite landform, while the joint function is the main cause of rock peaks and strange rocks, and also affects the dev...
