Sito on-line per identificare i minerali da un punto di vista macroscopico

In questo sito on-line della Mineralogical Society of America (MSA) vi è un utile e pratico sistema per l'identificazione macroscopica dei minerali in funzione delle proprietà fisiche.

We wish to make this key available to one and all in the hope of correct identification of minerals in collections, rock gardens, and on windowsills everywhere. You may copy it, or any part of it, for non-commercial, personal use.

We thank Lloyd Brown, David Jacobson, and Alfred Ostrander. Their excellent advice and encouragement in this project was extremely helpful. ©2003,  Alan Plante, Donald Peck, & David Von Bargen. In cooperation with Mindat.org.

This Mineral Key is designed and intended for use on-line. The premise behind this Key is similar to that of the identification keys found in some fern and wildflower books: Key diagnostic properties are used to direct users to tables where further information on "likely suspects" is found.  That information is then used to narrow down the choices to one or a few of the most likely minerals.  Then more detailed information can be found in a mineral guide book or website databases such as Mindat, Webmineral, or the MSA's "Handbook of Mineralogy" in order to make a final determination of the mineral in the sample.
