ABSTRACT

In this study, the weathering forms on the andesite of volcanic Mount Ağın (1807 m) located within the borders of Afyonkarahisar province in the Central Western Anatolia part of the Aegean Region were investigated. The climatic characteristics of the study area, chemical and mineralogical-petrographic properties of the andesites, porosity, diaclase systems, and biogenic erosion cause formation of characteristic shape generations on the andesites. In the field, andesites have been weathered by mechanical effects based on salt crystallization, freeze-thaw, shrinkage-expansion, and by the chemical effects of waterbased on hydrolysis-hydration-oxidation. The weathering product formed as a result of differential weathering has been subsequently moved by erosion, and the unweathered parts came to the surface to form distinctive forms in the topography. Weathering forms seen on the andesites have been investigated in detail for the first time in Turkey. The aim of this study is to reveal the close relationship between erosional forms of “andesite topography” and the factors playing a significant role in the formation of these weathering features. According to field observations and laboratory analyses, the original weathering forms on the mass have been explored and classified, and consequently revealed their formation mechanism and morphometric properties.

摘要

在这项研究中，调查了位于爱琴海地区安纳托利亚中西部部分阿菲永卡拉希萨尔省边界内的艾恩火山安山岩（1807 米）的风化形式。研究区的气候特征、安山岩的化学和矿物岩石学特性、孔隙度、斜长岩系统和生物侵蚀导致安山岩特征形状世代的形成。在野外，安山岩受到基于盐结晶、冻融、收缩-膨胀的机械作用以及基于水解-水合-氧化的水的化学作用的风化作用。差异风化形成的风化产物随后被侵蚀移动，未风化部分浮出地表，形成独特的地貌形态。土耳其首次对安山岩的风化形式进行了详细研究。本研究的目的是揭示“安山岩地貌”的侵蚀形式与在这些风化特征形成中起重要作用的因素之间的密切关系。根据野外观察和实验室分析，对块体上的原始风化形态进行了探索和分类，揭示了其形成机制和形态特征。
