Abstract
ABSTRACTThe Oamaru diatomite is a late Eocene deposit inland from Oamaru, North Otago, composed largely of siliceous microfossils—diatoms, sponge spicules and Radiolaria. It probably became known to British microscopists from a sample shown by Sir James Hector in the Indian and Colonial Exhibition in London in 1886. Subsequently, it became famous among amateur microscopists and professional diatomists around the world for the enormous diversity and beautiful preservation of its diatom flora. Although it continues to be well-known among diatomists, few New Zealanders currently know of it or appreciate its significance. Narratives, sites and artefacts associated with the Oamaru diatomite inform The Glass Archive, a photographically-based project which considers the material within an arts context.
