(American Heritage® Dictionary of the English Language, Fourth Edition)


  • There is one very beautiful specimen of shining white, fine-grained granite aplite, with small, pale red garnets.

    The South Pole~ Fram Expedition Geology

  • The former deposits contain arsenopyrite and copper-bearing pyrite impregnating a mica-quartz-schist, adjacent to and in apparent genetic relation with aplite or pegmatite intrusives.

    The Economic Aspect of Geology

  • The strongest mineralization encountered was a zone of intercalated "salami" granite, andesite, and aplite containing a stockwork to sheeted quartz + pyrite veinlets with visible gold, identified in a hole located approximately two kilometres southeast of the deposit.

  • Of the five holes that intersected the mineralized quartz pebble conglomerate (QPC), assays were consistent with the average historical grades, but below the conglomerate beds IMT intersected mineralized aplite dykes and sills, as well as highly altered mineralized breccia at the unconformity between the Archean basement rocks and overlying Proterozoic sediments.
