Abstract

THERMAL CONTACT WITH THE VOLCANIC ROCK AT KAMIONNA NEAR BOCHNIA (Carpathians)South of Bochnia V. Uhlig (1838) discovered a few occurrences of andesites and dacites. Their geological position and age have been established only recently by K. Skoczylas-Ciszewska (1956) who stated that the rocks in question occur as veins or tuffaceaus intercaIations in sediments of Upper Cretaceous and Paleocene age. Thus these rocks may correspond with the volcanic rocks of the Wadowice area described by A. Gaweł, M. Książkiewicz (1936) and T. Wieser (1954).While Upper Cretaceous-Paleocene age of the tuffs in both areas area has been proved beyond doubts (aIso Lower Eocene tuffs have been found, Książkiewicz 1956) the age of volcanic rocks was not cIearly stated; neither in the Wadowice area (Lanckorona) nor in the Żegocina region. In either areas volcanic rocks occur as large or small blocks in zones of very complex structure and, so far in no case a termally altered contact has been found.
