Kambr w Górach Świętokrzyskich (w l00-lecie odkrycia)
Abstract
THE CAMBRIAN PERIOD IN THE HOLY CROSS MOUNTAINS (CENTENARY OF STATEMENT)
Summary
Hundred years ago G. Gürich (5) had printed first publication concerning the Cambrian age of the rocks and trilobites from the outcrop Góry Pieprzowe, situated near the town Sandomierz on the Vistula River bank (Fig. 1A). The age of these rocks was recognized by earlier geologist as Silurian. A remarkable progress in Cambrian research was made by Jan Samsonowicz (19, 21, 22) and Jan Czarnocki (1-3), but unfortunatelly the collections of Cambrian trilobites and other fossils gathered by these both geologists were almost completly burned and devastated in Warsaw in 1944. After the war the young genaration of geologists started with extensive mapping in the field and exploration of fossils. Un till our times lithology and sedimentology of the Cambrian sequence was recognized; paleontological descriptions of: trilobites, brachiopods, hyolithids, jellyfishes, archeocyathids and algae were published; Cambrian trace fossils were recognized and described. A synthesis of the Cambrian stratigraphy was made; lithostratigraphic, biostratigraphic and chronostratigraphic unites were formalized (11, 15, 17; Fig. 3). Data concerning the Cambrian stratigraphy of this area were presented during the International Geological Congresses in: Madrid 1926, Mexico 1956, Kopenhagen 1960, Prag 1968, Moscov 1984. This centenary makes a good oportunity to present new directions of researches concerning the Cambrian sequence in the Holy Cross Mountains, which should be realised in the coming years.
