American Heritage® Dictionary of the English Language, Fourth Edition
- n. Worthless rock or other material in which valuable minerals are found.
Century Dictionary and Cyclopedia
- n. In mining, the non-metalliferous or earthy minerals accompanying the ore in a vein or mineral deposit; the part of a lode which is not called ore, or which has no commercial value; veinstone. Quartz is the most abundant veinstone; calcite, heavy-spar, fiuor-spar, and brown-spar are also commonly found forming more or less of the bulk of the metalliferous lodes. Sometimes the gangue prevails in the vein to the entire exclusion of ore. The words gangue and veinstone are not properly used to designate the material with which the ore is associated when this consists chiefly of fragments of the country-rock mingled with fiucan, etc. This is what the miners designate as the filling-up. See
veinand comb, 6.
- n. In mineral analysis, the foreign material or impurity present with the mineral under examination.
GNU Webster's 1913
- n. (Mining) The mineral or earthy substance associated with metallic ore.
- French, from German Gang, lode, from Middle High German ganc, from Old High German gang, a going. (American Heritage® Dictionary of the English Language, Fourth Edition)
