Backscattered Electron Microscopy as an Advanced Technique in Petrography

摘要: We believe that backscattered electron microscopy is a technique will revolutionize the study of fine-grained sediments and sedimentary rocks components coarse-grained materials such as sandstones. The produces images with resolutions about ten times better than those obtained visible-light petrographic microscope. Additionally, mineral contrast function average atomic number atoms in minerals imaged, thus related to mineralogy, which can be determined by using energy-dispersive X-ray analysis combination microscopy. Three examples applications method sandstones, desert varnish granite weathering are described below. results could not have been acquired either petrography or any other common method. Finally, it appears commonplace next decade should available both undergraduate graduate stude...
