Segnitite (original) (raw)
La segnitita és un mineral de la classe dels fosfats, que pertany al grup de la dussertita. Rep el nom en honor d'Edgar Ralph Segnit (Adelaida, Austràlia, 5 de setembre de 1923 - Melbourne, 13 de juliol de 1999), geòleg i gemmòleg a la divisió de química mineral de CSIRO a Melbourne, per les seves contribucions a la mineralogia australiana.

El nombre es un homenaje a Edgar Ralph Segnit (1923-1999), que trabajó como geólogo y gemólogo en el CSIRO, Melbourne (Australia). (es) Segnitite is a lead iron(III) arsenate mineral. Segnitite was first found in the Broken Hill ore deposit in Broken Hill, New South Wales, Australia. In 1991, segnitite was approved as a new mineral. Segnitite has since been found worldwide near similar locality types where rocks are rich in zinc and lead especially. it was named for Australian mineralogist, gemologist and petrologist Edgar Ralph Segnit. The mineral was named after E. R. Segnit due to his contributions to Australian mineralogy. Segnitite is not a primary ore mineral, but is found amongst other well known ore minerals such as galena, sphalerite, pyrite and more. Many minerals found with segnitite are important for industrial purposes. Minerals associated with segnitite make up metal alloys, batteries and even pigments. Carminite and are closely related to segnitite. In fact, forms of beudanite are commonly confused with segnitite, as the sulfate and arsenate anions readily exchangeable with each other. Other mineral relations include, goethite, coronadite, agardite, bayldonite, and mimetite. Set parameters for the space group and chemical composition have yet to be confirmed. Segnitite has loose boundaries and conclusions about segnitite were derived from associated minerals. Chemically, there are many varieties of segnitite which affects space group measurements and chemical analysis interpretations. In other words, segnitite samples from around the world can be very different from one another making it difficult to provide accurate chemical measurements. (en) La segnitite è un minerale appartenente al gruppo della dussertite descritto nel 1992 in base ad un rotrovamento avvenuto a Broken Hill, Nuovo Galles del Sud, Australia. Il nome del minerale è stato attribuito in onore del mineralogista australiano E. Ralph Segnit. La segnitite è l'analogo della philipsbornite contenente ferro al posto dell'alluminio. È molto simile alla beudantite tanto che in un primo tempo era stata confusa con essa. (it) |
