Diatoms may occur in such large numbers and be well preserved enough to form sediments composed almost entirely of diatom frustules (diatomites), these deposits are of economic benefit being used in filters, paints, toothpaste, and many other applications. Abstract diatoms were found in late holocene age ice-core samples recovered from the quelccaya summit dome in the tropical andes of peru and were imaged by environmental scanning electron microscopy and identified freshwater diatoms in the genera hantzschia, pinnularia, and aulacoseira were the most common taxa in the samples and indicate a freshwater source for the material, which also is.
