peralkaline granite with gold

The peralkaline composition of the Sams Creek granite and the absence of molybdenite and paucity of chalcopyrite, are major points of difference with gold-rich porphyry copper deposits. The presence of a lowsulf idation-state ore mineral assemblage, carbonate alteration and carbonic fluid inclusions at Sams Creek are typical of many of the reduced granitic intrusion-related type ofgolddeposit.

    Peralkaline granite Graniteis a medium-tocoarse-grained acid igneous rock with essential quartz (>20%) and feldspar, where alkali feldspar constitutes between 100 and 35% of the feldspars, and minor mafic minerals. Hornblende and biotite are the commonest mafic minerals, however, muscovite is also frequently encountered.

    The natureand origin of gold mineralization at Sams Creek

    Gold mineralization is hosted by a peralkaline granite dyke which outcrops over about eight kilometers in the area of Sams Creek, a tributary of the Takaka River, north-west Nelson. The granite is riebeckite and acmite bearing, with antiperthitic alkali feldspars; it has A-type chemistry, implying an origin by partial melting at a temperature > 800°C.
