原为内陆海或湖的威特沃特斯兰盆地近似椭圆形,南西北东走向长约350公里、宽150公里。自1886年在地表露头砾岩中首次发现黄金以来,在此盆地的四周已发现7个大型金矿田。然而,黄金储量正在迅速枯竭,产量已从1970年的1000吨最高峰下降到 The original Wittland Basin, an inland sea or lake, is nearly oval in shape, with a length of about 350 kilometers and a width of 150 kilometers in the east and south of the country. Since the first discovery of gold in surface outcrop conglomerates in 1886, seven large gold fields have been discovered around this basin. However, gold reserves are rapidly depleting and production has dropped from a peak of 1,000 tons in 1970
