Type: Vanadium in an asphaltite (sulphur-rich bitumen)

Former large vanadium deposit with patrónite (VS4) in a sulphur-rich Cenozoic bitumen, formed at about 90-180 °C (below 80 °C by other estimates); V-rich hydrothermal fluids as the main source according to Haggan and Parnell (2000). Schuth et al. (2017): patrónite at +0.43 and +0.22 ‰ (δ51V, two digestions), with associated bravoite.
