Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Microinclusions of Re-, Mo-, Cu-, Pb-, and Bi-bearing sulfides are found for the first time in Cu sulfide ores of the Maike occurrence, northern Ulytau. The microinclusions are characterized by various morphologies and chemical compositions. According to microprobe data, eight sulfides contain up to 49.46 wt % Re, as well as Fe, Cu, Mo, Pb, and Bi. The formulas of sulfides are (Re,Mo,Cu ± Fe,Os,Pt)2S3, (Re,Mo)S2, ReS3, Re2S7, (Pb,Re,Zn)S2, (Pb,Re,Fe)S2, (Pb,Re,Fe)2S3, and (Re,Fe)(Pb,Bi)S3. For the first time, we identified a previously unknown Pb–Re–Zn–S phase, a Rh and Sb assemblage in a Re–Fe–Pb–Bi–S mineral phase, and ReS3 and Re2S7 sulfides.
