definition
noun
Specifically, gangue formed by both metasomatic alteration and precipitation during ore formation can yield a wealth of information about the origins and physical conditions of the ore-forming fluids.
the commercially valueless material in which ore is found.
example
Don't you think that in some cases these nuggets have got to be cleared of their 'gangue' ?
good ore with some 'gangue' or rock adhering
Here, too, the veins may be monomineralic, commonly quartz or calcite, but more usually are polymineralic with a mixture of metalliferous sulphide or oxide minerals and 'gangue' minerals.
The main ore minerals are galena, chalcopyrite, sphalerite, and tetrahedrite that are associated with quartz and barite 'gangue' .
Chlorite, predominantly magnesium chlorite, is the principal 'gangue' , and its intimate association with the uraninite indicates that the two minerals formed together.
At that time, the museum acquired the Colorado State Collection, which has high historical value because it contains many ore and 'gangue' specimens from now-closed and abandoned Colorado mines.
Native copper and a host of 'gangue' minerals were deposited in fissure veins, brecciated and fractured vesicular lava flow tops, and conglomerate beds during the same period of metal mineralization.
It is a 'gangue' mineral in ores from the Star, Hobo, and Princess mines at Central, Grant County.
The major ore and 'gangue' minerals are given in the table, but only those of interest to collectors are discussed in detail below.
It is associated with all ore minerals as well as most 'gangue' minerals.
They noted that in the Champion mine siderite is abundant, occurring as the chief 'gangue' mineral of the sulfide ores in the dolomitic beds in the Sawatch Quartzite.
The main 'gangue' minerals are quartz and barite.
Rhodonite is found as a 'gangue' mineral in hydrothermal silver veins cutting volcanic rocks in the Pacocollo, Carangas, and Todos Santos areas, Bolivia.
Uraninite occurs with cobalt, nickel, arsenic, and silver minerals in a carbonate 'gangue' at the Solitaria mine, Jaguel district, Argentina.
The main 'gangue' minerals that make up the vein are massive white calcite, quartz, and prehnite.
Specifically, 'gangue' formed by both metasomatic alteration and precipitation during ore formation can yield a wealth of information about the origins and physical conditions of the ore-forming fluids.
A short drift and crosscut were driven off the back of the cavity in search of ore, but only low-grade mineralization consisting of chalcopyrite, galena, and sphalerite in a siliceous 'gangue' was encountered.
Here the galena is massive, with 1-3 - mm-wide cleavage planes scattered across the quartz 'gangue' surface of the specimen.
Exceptionally well-crystallized zinc-bearing rhodonite was a locally abundant 'gangue' mineral at Franklin and, to a lesser extent, Sterling Hill, Sussex County, New Jersey.
The fluorite is typically a 'gangue' mineral and is only locally recovered as an ore.
Rhodonite is described in the technical literature as a widespread and locally abundant 'gangue' mineral in many of Colorado's precious-metal vein deposits.
