Examples

  • 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 chemistry of the process of petrifaction or silicification," writes

    The Book of the National Parks

  • Best results are from two of the four drillholes at Zone 4, where elevated gold values are associated with zones of brecciation and silicification.

  • Previous drilling and a 2004 Gradient Array Resistivity geophysical survey indicate potential for identifying economic quantities of high-grade gold and silver mineralization in the Capgold epithermal system, as most of the gold and silver identified at Capgold to date has been found within large zones of silicification which are receptive to identification by resistivity measurement surveys.

  • Gold intercepts at Hidden Treasure are from a near-surface, sub-horizontal mineralized zone characterized by massive silicification, as well as a deeper, higher-grade, southwest-dipping zone.

  • Hasbrouck mineralization was deposited by an epithermal hot-spring system and is accompanied by pervasive silicification and oxidization, with associated adularia and pyrite.

  • Smaller zones of silicification are associated with the margins of both breccia bodies.

  • Mineralisation in the Tulkubash Zone is hosted in silicified quartzites and mineralised zones exhibiting pervasive silicification and some argillic alteration, together with elevated contents of sulphides at depth of up to 5%-10% of volume.

  • No mineralization was intersected, but silicification was encountered in Athabasca sandstones in three holes, and there was low-level elevated radioactivity more than twice and locally up to four times background, also in sandstones, in all five holes.

  • It encountered moderate to strong silicification in Mfb from 318.5 to 375.7 metres and patchy silicification in Mfa from 375.7 to 398.6 metres, in which was a section of elevated radioactivity from 386 to 392 metres.
