Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. Pyrite is a common minor component of the sedimentary exhalative (SEDEX) Zn-Pb deposits and of the immediate host carbonaceous mudstones in the Howard¿s Pass district, Selwyn Basin, Yukon. It occurs as framboids, bedding-parallel wispy to well-formed bands, nodules and porphyroblasts. We have used laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) and electron-probe microanalysis (EPMA) to study multigenerational pyrites to better constrain the trace element and isotopic compositions of sedimentary exhalative mineralizing, diagenetic and metamorphic fluids in the Howard¿s Pass district.
