本文介绍了利用ＩＥＬＴＺＴＡＳＡ—ｐｌｕｓ型图像分析仪进行沉积岩微区形貌及成分定量分析的方法，如沉积岩粒度分析、矿物（或组分）定量测量、面孔率及微裂隙的定量测量等，并与其它方法作了比较。研究结果表明，该方法具有快速、精确和统计信息量大等优点，但对于许多岩矿样品来说，灰度自动检测比较困难，而需要结合操作者的地质学知识和经验通过光笔装置进行半自动测量。最后对图像仪在地质学中的应用前景作了分析。
This paper introduces the method of using IELTZTASA-plus image analyzer to analyze the morphology and composition of sedimentary rocks, such as sedimentary rock size analysis, quantitative measurement of mineral (or component), the measurement of face porosity and micro-cracks, etc. Other methods are compared. The results show that this method has the advantages of fastness, precision and large amount of statistical information. However, for many rock samples, automatic grayscale detection is more difficult, and it needs to be combined with the operator’s geological knowledge and experience to semi-automatically measuring. Finally, the application prospect of imager in geology is analyzed.
