- W61783887 abstract "The Robinson Creek Gold Occurrences, situatedapproximately, 12 kilometers southwest of Flin Flon,Manitoba, are of the typical quartz vein type. Mineralizedquartz veins are contained within shear zones, hostedwithin rocks which may represent structurally deformed,metamorphosed and chemically altered, mafic volcanic flowsand or related pyroclastic rocks of the Amisk Groupvolcanics. Metamorphosed intermediate to felsic volcanicrocks (dacite to rhyolite), also belonging to the AmiskGroup, are found stratigraphically above the maficvolcanics, and may represent former volcanic flows andrelated pyroclastic rocks. These rocks are intruded by twovarieties of porphyritic dacite to rhyodacite ofcontrasting age. The Amisk volcanic rocks are overlain byhighly deformed conglomerates and rare sub-arkosicsandstone of the Missi Group sediments. Clasts in theconglomerate were probably derived from the underlyingAmisk volcanics (Stauffer and Mukherjee, 1971).The Amisk volcanics probably represent a transitionfrom tholeiitic to calc- alkaline chemical affinities (Fox,1976, Walker and Watters, 1982) and perhaps from an oceanfloor to an island arc setting (Stauffer, 1974). However,all of the rocks in the area have been affected by severalphases of deformation and are metamorphosed to greenschistto lower amphibolite grade. Chemical alteration of therocks has been enhanced be penetrative deformation, mostnoticeable in the Robinson Shear system which hosts thegold.The typical secondary assemblage is ferroan dolomite(ankerite), quartz, chlorite, muscovite (sericite), pyriteand locally tourmaline. Carbonate alteration (ankerite),predates the introduction of the gold-bearing quartz veinsin the sheared mafic volcanics. Metasomatic alteration ofthe mafic rocks associated with gold mineralization istypified by an enrichment in Rb, Sr, and K and depletion inNa, Ca, and variably Mg. Metasomatism is generallyassociated with a volume increase in sheared rocks and avolume reduction in rocks with minor penetrativedeformation.The gold-bearing quartz veins are interpreted to be ina dilatent zone hosted within two shear zones located nearthe hinge of a tightly closed anticline with a steeplydipping axial surface." @default.
