在Waihi安山岩中的巨大石英脉系统中,存在一个很大的浅成低温热液金—银矿床(总共生产了约199tAu和约1243tAg,Ag:Au=6.2)。金—银工业矿石向下延伸达575m。大面积的冰长石—石英—伊利石—绿泥石—黄铁矿蚀变带与较大的石英脉相邻并伴生石英+方解石+黄铁矿±冰长石±伊利石细脉
In the huge quartz vein system in the Waihi andesite, there is a large epithermal gold-silver deposit (total production of about 199 t Au and about 1243 t Ag, Ag: Au = 6.2). Gold - silver industrial ore extends down to 575m. Large area of feldspar - quartz - illite - chlorite - pyrite alteration zone adjacent to the larger quartz veins associated with quartz + calcite + pyrite ± ice feldspar ± illite vein
