Abstract

This paper introduces the identification methods and formation environment speculation of common rocks in parks and mountainous areas. First, this paper categorizes rocks into three types: magmatic rocks, sedimentary rocks, and metamorphic rocks. The identification characteristics of color, particle, and structure of common rocks, such as granite, basalt, sandstone, limestone, and marble, are described in detail for each category. Additionally, it combines the cooling rate, sedimentary environment, and metamorphic degree to infer the formation environment of rocks. For example, granite is formed in deep underground magma chambers, and limestone is mostly derived from ancient shallow seas. It offers practical steps for identifying rocks and making inferences, highlighting that rocks serve as "recorders" of the Earth's geological history. Understanding their identification can enhance people's appreciation of natural evolution and enrich outdoor experiences.
