Uranium-lead ages from an ion probe were taken for zircons from the ore-bearing Noril'sk I intrusion that is comagmatic with, and intrusive to, the Siberian Traps. These values match, within an experimental error of +/-4 million years, the dates for

Analyses by electron microprobe have disclosed unexpected complexity in the mineralogy of the Ag-Bi-bearing galena ores at Darwin, yet reveal that these elements are carried predominantly in solid solution in PbS. Darwin "galena" can be divided into

An emission spectrographic method for the determination of minor elements occurring in natural sulfides has been developed. This method involves the use of complex crystalline standards, synthesized at elevated temperatures, that contain within their

Six analytical techniques for the selective chemical dissolution of sulfides are compared with the purpose of defining the best method for accurately determining the concentration of sulfide-bound nickel. Synthesized sulfide phases of known elemental

The Wood River lead-silver deposits, near Bellevue in south-central Idaho, occur in veins in sheared zones in contact metamorphosed siliceous and limy argillites of Mississippian age near contacts with quartz diorite. Galena and sphalerite are the pr
