Typical Au-bearing sample at Loma Larga (IQD-122, ca 188 m). The sample pertains to a 12.8 m long portion with 20.8 g/t Au, 57.2 g/t Ag, 0.3% Cu).
It consists of residual quartz, replaced by fine pyrite, locally with a botryoidal texture; open spaces filled by barite.
The general fabric may correspond to a lapilli tuff being some of the vuggy textures after lapilli (consistent direction of flattening of open spaces).
