Journal ArticleDOI
Mechanism of molybdenum removal from the sea and its concentration in black shales: EXAFS evidence
George R. Helz,C.V. Miller,John M. Charnock,John M. Charnock,J. F. W. Mosselmans,Richard A. D. Pattrick,C D Garner,David J. Vaughan +7 more
TL;DR: In this article, the authors introduce the concept of a geochemical switch, in which HS- transforms the marine behavior of a conservative element to that of a particle reactive element, and the action point of the HS- switch is calculated to be, a(HS)- = 10(-3.6) - 10(-4.3).
Journal ArticleDOI
Variations in the compositional, textural and electrical properties of natural pyrite: a review
TL;DR: In this article, the results of a review that has been conducted to establish the range in variability of natural pyrite with regard to chemical composition, texture and electrical properties are presented.
Journal ArticleDOI
Electrical and magnetic properties of sulfides
TL;DR: In this article, the theory and measurement of electrical and magnetic properties of sulfide minerals are outlined along with spectroscopic and diffraction studies that can provide insights into magnetic behavior.
Journal ArticleDOI
Fluid inclusion noble gas and halogen evidence on the origin of Cu-Porphyry mineralising fluids
TL;DR: The naturally occurring noble gas isotopes (40Ar, 36Ar, 84Kr and 129Xe) and halogens (Cl, Br, I) have been determined simultaneously in irradiated quartz vein samples by noble gas mass spectrometry as discussed by the authors.
Journal ArticleDOI
The structure of amorphous copper sulfide precipitates: An X-ray absorption study
Richard A. D. Pattrick,J. F. W. Mosselmans,John M. Charnock,K.E.R. England,George R. Helz,C D Garner,David J. Vaughan +6 more
TL;DR: X-ray absorption and X-ray photoelectron spectroscopy (XPS) analysis of copper sulfide precipitated from aqueous solution at ambient temperatures reveals the existence of a metastable primitive structure that ages to a structure with the characteristics of amorphous covellite as discussed by the authors.
