  • Here it is believed to be an alteration product of diopside (lime-magnesia pyroxene) in a contact-metamorphic silicated zone.

    The Economic Aspect of Geology

  • Extensive alterations of the country rock in the way of silicification and sericitization, and the presence of minerals like garnet, tourmaline, diopside, and others, known to be commonly deposited by the same hot solutions which make many ore deposits, may furnish a clue for exploration below.

    The Economic Aspect of Geology

  • The primary deposition was of chalcopyrite and other copper sulphides, together with garnet, diopside, and other minerals known to have required high temperature in their formation.

    The Economic Aspect of Geology

  • Totals of 1,673 p-type garnets and 287 e-type garnet grains were recovered, with one sample returning 50 p-type garnets, ten e-type garnets, four chrome diopside and one ilmenite grain.

    The Earth Times Online Newspaper

  • In 2009, 1,273 KIM samples were collected under a sampling campaign that had two objectives: initial evaluation of portions of Nanuq that had not previously been evaluated by KIM sampling and follow-up sampling related to previously identified KIM and geophysical anomalies. 482 of the 1,273 samples contained kimberlitic indicator minerals including at least one p-type garnet, e-type garnet, chrome diopside or ilmenite grain, with 100 of the samples returning over five of these grains.

  • Both phases contain olivine, picroilmenite, pyrope garnet and chrome diopside macrocrysts.

    The Earth Times Online Newspaper

  • Pyrope garnet, picroilmenite and chrome diopside grains over 10 millimetres in size were observed on the surface.

  • - Anomalous kimberlite indicator minerals (pyrope garnet, chrome diopside, ilmenite and chromite) in tills have provided a target area focus.
