光学显微镜下,展现在我们眼前的是一个神奇的世界。每一张岩石薄片就象一个变幻无穷的万花筒,光怪陆离,千姿百态。我们看到的就是由中国地质博物馆采集、制做的100种岩浆岩薄片。达套薄片囊括了超基性岩、基性岩、中性岩、酸性岩以及脉岩五大类,共100种典型的岩浆岩。通过这套薄片,我们可以详细了解各种岩浆岩的矿物成分、结构、构造;掌握各种常见造岩矿物的光学特性、常用光学参数等。除此之外,我们还可以观察到一些自然界中不常见的透明矿物和一些矿物假象。在这套薄片的说明书中,还附有每一种岩石的产地、产状,显微照片和部分标本的全岩化学分析数据,可以说是一套资料完整,形象生动的好教材。
Under the light microscope, what appears before us is a magical world. Each rock slice is like a changing kaleidoscope, bizarre, different. All we have seen is the 100 kinds of magmatic rocks collected and made by the China Geological Museum. Dadaoshuo contains over 100 types of typical magmatic rocks, including ultrabasic rocks, basic rocks, neutral rocks, acidic rocks and vein rocks. Through this sheet, we can learn more about the mineral composition, structure and structure of various magmatic rocks; to master the optical properties of various rock-forming minerals, commonly used optical parameters. In addition, we can also observe the illusion of some transparent minerals and some minerals that are not common in nature. In this leaflet, the complete petrochemical analysis of the origin, appearance, micrographs, and some specimens of each rock, together with a complete set of vivid textbooks, is also available.
