| Abstract: | This paper introduces a kind of new technology of an image-analysis technique to obtain grain-size data,and selects a pure quartz sandstone with a litter garnet in Wuli Group of the Qinghai-Tibet Plateau region as a study case object,and to carry out a detailed analysis of grain-size.The results show that this technique is not only reliable,easy and convenient,but also fast in detection,accurate in measurement,and stable in result.Image analysis consists of all operations necessary to obtain quantified information from images,including image acquisition,image processing,measurements,data processing,and interpretation.It will be available to a wide range of applications in sedimentology field. |
