Collecting and Examining Beach Sand: Getting Started
Published online by Cambridge University Press: 14 March 2018
Extract
Grains of sand collected from the beach may be examined for a number of reasons. From the youngster who first peers at a handful of beach sand under a magnifying glass to see the various shapes and colors to the sedimentologist who studies sand grains for clues to the questions of plate tectonics, the collection and examination of sand can be a fascinating activity. Dr. Oliver H. Howe, in an interesting article published in 1946, remarked of one sand sampie that under a low power magnifier the various colors of garnet grains contrasted strikingly with the black grains of magnetite, green of epidote and the brilliant grains of quartz.
