The system O-S-Fe at 1 bar
Article Abstract:
The dominant components of natural sulfide liquids that make up the O-S-Fe system were analyzed to characterize the thermochemistry and physical properties of sulfide liquids. Equilibration of the sulfide liquids under controlled oxygen and sulfur frugalities indicated the inverse correlation of the oxygen and sulfur contents. The thermodynamic model depicting the physical and thermochemical properties of the sulfide liquids also indicated the inverse correlation between oxygen and sulfur.

Geochemistry of tholeiites from Lanai, Hawaii
Article Abstract:
An analysis of tholeiite geochemistry found in the Lanai islands of Hawaii is presented. The Lanai ranks as the island's third smallest among 15 subaerial shield volcanoes in the area. Major and trace element analyses were applied to samples of the area. It is shown that Lanai tholeiites covered a wide range in composition. In addition, these tholeiites were developed through different amounts of partial melting.

Geochemistry of Tertiary tholeiites and picrites from Qeqertarssuaq (Disko Island) and Nuussuaq, West Greenland with implications for the mineral potential of comagmatic intrusions
Article Abstract:
The geochemistry of Tertiary continental flood basalts on Qeqertarssuaq and Nuussuaq in West Greenland are studied. It is shown that the tholeiitic lavas from the Qeqertarssuaq and Nuussuaq are contaminated by various crustal materials defining two separate contamination trajectories on geochemical variation diagrams. It is also shown that most of the contamination are also Ni and Cu deplated.
