Element partitioning in magnetite under low-grade metamorphic conditions – a case study from the Proterozoic Belt Supergroup, USA
Autor: Patrick Nadoll, Alan E. Koenig, Timothy S. Hayes, Stephen E. Box, Jeffrey L. Mauk
Publikováno v: European Journal of Mineralogy. 29:795-805
The distribution and partitioning of elements in igneous rocks is well established for various melt–(fluid)–solid pairs and provides important insights into the petrogenesis of these rocks. Studies of the partitioning behavior of elements under m

Xenotime occurs as epitaxial overgrowths on detrital zircons in the Mesoproterozoic Revett Formation (Belt Supergroup) at the Spar Lake red bed-associated Cu-Ag deposit, western Montana. The deposit formed during diagenesis of Revett strata, where ox

The Spar Lake Strata-Bound Cu-Ag Deposit Formed Across a Mixing Zone Between Trapped Natural Gas and Metals-Bearing Brine
Autor: Richard J. Moscati, Timothy S. Hayes, Gary P. Landis, Robert O. Rye, Joseph F. Whelan
Publikováno v: Economic Geology. 107:1223-1249
Ore formation at the Spar Lake red bed-associated strata-bound Cu deposit took place across a mixing and reaction zone between a hot oxidized metals-transporting brine and a reservoir of “sour” (H2S-bearing) natural gas trapped in the host sandst

Geochemistry of Magnetite from Hydrothermal Ore Deposits and Host Rocks of the Mesoproterozoic Belt Supergroup, United States
Autor: Stephen E. Box, Alan E. Koenig, Jeffrey L. Mauk, Patrick Nadoll, Timothy S. Hayes
Publikováno v: Economic Geology. 107:1275-1292
Magnetite (Fe 3 O 4 ) is a common and widespread accessory mineral in many host rocks and mineral deposits. We used electron microprobe analysis (EMPA), laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis, and oxygen isot
