“…None of these are from tin ores, as are the determinations of the samples reported on here. Eecent work by Waters, Burton, Clements, Lovesey, andMorris (1965, p. 1297) shows that fluorites from various tin-bearing areas contain no more than 11 ppm beryllium but that many contain more than 5 ppm. These authors show that fluorite precipitated from beryllium-rich solution can contain as much as 900 ppm beryllium (p. 1299).…”

A reconnaissance study of the geochemical cycle of tin, beryllium, boron, lithium, tungsten, copper, lead, zinc, and niobium in the tin-beryllium district of the western Seward Peninsula, Alaska, shows that the biotite granite stocks are enriched in beryllium as compared with other tin-granites, and that most elements moved outward from the stocks into the thermally metamorphosed rocks aiid skarns around the stocks. Following the consolidation of the exposed granites, a strong set of normal faults developed in the central York Mountains; dikes of rhyolite, rhyolite porphyry, diabase, arid lamprophyre were injected into many of the faults. After the faulting and the injection of dikes, lodes of tin, tungsten, beryllium, and fluorite were formed in which all the trace elements were greatly enriched. Individual minerals from the lodes contain anomalous amounts of trace elements and, irrespective of their position in the zoned ore deposits, point clearly to the passage of solutions enriched in the elements studied.In supergene processes, clearcut geochemical anomalies were formed in stream sediments, soils, and plants of the area. Except possibly for zinc and silver all the elements investigated remain associated throughout the geochemical cycle. Tundra plants concentrated most elements to a degree, but for beryllium, and to a lesser degree tin and niobium, there is a point at which soil concentration invariably exceeds that of plant ash. The single lichen investigated concentrates silver but has a low content of other elements.Anomalous amounts of many rare metals in igneous rocks can possibly host be detected by analyses of the bulk heavy-mineral fraction having a specific gravity greater than that of methylene iodide (3.29).
