Chromite – Platinum-Group Element Magmatic Deposits

The role of surface geochemistry in the discovery of the Babel and Nebo magmatic nickel–copper–PGE deposits

The inexpensive geochemical exploration technique based on broadspaced deflation lag sampling played a key role in the discovery of the Babel and Nebo ortho-magmatic Ni–Cu–platinum group elements (PGE) deposits. An area of 1100 km in the western Musgrave Block in central Australia was explored using deflation lag samples collected on a 1 km 0.5 km grid. A total of 35 elements were determined us...

Atmospheric sulfur in Archean komatiite-hosted nickel deposits.

Some of Earth's largest iron-nickel (Fe-Ni) sulfide ore deposits formed during the Archean and early Proterozoic. Establishing the origin of the metals and sulfur in these deposits is critical for understanding their genesis. Here, we present multiple sulfur isotope data implying that the sulfur in Archean komatiite-hosted Fe-Ni sulfide deposits was previously processed through the atmosphere a...

Properties of Electroless Nickel - Phosphorus PPF Deposits after Crystallization

t is well recognized that electroless I.' nickel-phosphorus offers excellent deposition characteristics, such as uniform coverage, freedom from porosity, hardness, corrosion resistance, solderability, braze and weldability, wear resistance and lubricity.' Interest in the properties of electroless nickel has grown in recent years, leading to the development of wide-ranging applications, a compre...

Thermal and Fluid Dynamics of Komatiitic Lavas Associated with Magmatic Fe- Ni-Cu-(PGE) Sulphide Deposits

The most important examples of magmatic ore deposits in volcanic rocks are Fe-Ni-Cu-(PGE) sulphides associated with Archean and Proterozoic komatiitic lava channels (Lesher, 1989). Komatiitehosted ores contain ~25% of the world’s nickel sulphide resource (≥ 0.8% Ni), including significant amounts of copper and platinum group elements (Ross and Travis, 1981). Field, experimental, and theoretical...
