Abstract


QUARTZ VEINS IN THE VICINITIES OF BARCINEK IN THE IZERA HIGHLAND

In the vicinities of Barcinek, Izera Highland, the quartz veins occurring within gneisses run in two various directions: 1 - north-west - south-east and 2: - north-east - south-west.

The veins consist of three generations, at least. The first one represents the proper quartz vein partly broken down and even mylonitized. It shows an infiltration-corrosion character parallely to the foliation plane of covering rocks (210/70). lt was stated that the fragments of gneisses occurring in the veins of this generation are not dragged blocks, but they have been formed in situ.
