TLDR
In this paper, a curve relating composition of synthetic pentlandite with interplanar spacing was determined experimentally as follows: d115 ǫ = 1.9407 − 0.0077x2, where x represents the iron to nickel we...

The Chemical Compositions of Synthetic and Natural Pentlandite Assemblages

Kula C. Misra, +1 more
- 01 Jul 1973 - 
TL;DR: The phase relations of pentlandite assemblages in the Fe-Ni-S system have been investigated by sealed, silica tube annealing experiments at 600 degrees, 500 degrees, 400 degrees, 300 degrees, and 230 degrees C.

Phase equilibria at high temperatures

Michael E. Fleet
- 01 Jan 2006 - 
TL;DR: The literature on metal sulfide phase relations relevant to the earth sciences is very extensive and could not possibly be summarized in a single chapter as mentioned in this paper, however, following Craig and Scott (1974), this chapter focuses on the base metal (Fe, Co, Ni, Cu, and Zn) sulfides, with the literature for other metal chalcogenides and pnictides and some sulfosalts summarized in the single table (Table 1⇓).

Experimental simulations of sulfide formation in the solar nebula

Dante S. Lauretta, +2 more
- 18 Jul 1997 - 
TL;DR: The experimental sulfides are chemically and morphologically similar to sulfide grains in the matrix of the Alais (class CI) carbonaceous chondrite, suggesting that these meteoritic sulfides may be condensates from the solar nebula.

Chromite composition and PGE content of Bushveld chromitites: Part 1 – the Lower and Middle Groups

Anthony J. Naldrett, +6 more
- 01 Dec 2009 - 
TL;DR: In this paper, a plot of cation% Mg/(Mg + Fe2+) versus Cr/(Cr+Al) was calculated for the 19 chromitite horizons between the LG-1 and UMG-2 from 6 sectors around the Bushveld Complex, along with microprobe analyses of representative samples of 41 chromites.

Critical thermodynamic assessment and modeling of the Fe-Ni-S system

Peter Waldner, +1 more
- 01 Oct 2004 - 
TL;DR: In this article, a thorough review and critical evaluation of phase equilibria and thermodynamic data for phases in the iron-nickel-sulfur ternary system at 1 bar pressure has been made over the entire composition range for temperatures from 25°C to above the liquidus.

A refinement of the crystal structure of KSCN

C. Akers, +2 more
- 15 Aug 1968 - 
TL;DR: In this paper, the crystal structure of potassium thiocyanate has been investigated and two separate crystals, whose dimensions varied from 0.07 to 0-10 mm, were used to collect the data because the first began to decompose before the investigation was complete.

The central portion of the Fe-Ni-S system and its bearing on pentlandite exsolution in iron-nickel sulfide ores

A. J. Naldrett, +2 more
- 01 Sep 1967 - 
TL;DR: In this article, a detailed study of the central portion of the Fe-Ni-S system between 600 degrees and 250 degrees C has been conducted by means of silica-tube techniques.

The Fe-As-S system--Phase relations and applications

Lloyd A. Clark
- 01 Nov 1960 - 
TL;DR: In this paper, the As:S ratio in arsenopyrite and/or loellingite was investigated at confining pressures up to 2,070 bars, and the invariant temperature at which both liquid and vapor are present in these assemblages are 491 degrees + or - 12 degrees C, 688 degrees+ or - 3 degrees C., and 702 degrees +/ - 3DGC., respectively.
