- MINERALIUM DEPOSITA is the official bulletin of the Society for Geology Applied to Mineral Deposits. Beginning in 1999, frequency has increased from six to eight issues per year. It is "intended to be of interest to those engaged in field geology, mineral deposit research and ore deposit exploration." Issues contain a mixture of original research papers, review articles and rapid-communication letters and notes all dealing with economic geology and related topics in mineralogy and geochemistry. Many of the illustrations are in color, especially those of mineral thin sections. Coverage is truly international in scope and includes such often under-represented areas as Africa, Asia, Australia and South America. There are also thematic issues on selected ore deposits or other topics of general interest (Katz).
