With 6 Dutch friends we were on a Rockhounding trip in Spain in the autumn of 2017. We went to different locations in Northern Spain hunting for World Class crystals. On the 4th day, we visit Minglanilla. First we searched for Jacinto de Compostela quartz and then for World Class purple aragonite.
In Spanish mineralogical literature, the name Jacinto de Compostela is traditionally used exclusively for the red "floater" variety of authigenic quartzes from continental gypsum-bearing marls of the Triassic Keuper formation. (They may also be found occasionally in younger Tertiary or Quaternary sediments, but in these cases the crystals were eroded out of the Keuper F.)
