WebThe seven gold-silver deposits within the district show common features such as multiple complex veins, an abundance (up to 30% in ore) of base-metal sulphides, a wide range of Ag/Au ratios and the common occurrence of carbonate. Quartz-vein textures indicate open-space-filling at shallow crustal levels. WebJun 11, 2024 · In most representations of mass spectral data the intensity of the base peak is normalized to 100% relative intensity. This largely helps to make mass spectra more easily comparable. The normalization can be done because the relative intensities are basically independent from the absolute ion abundances registered by the detector.
