Název v původním jazyce

Petrology and geochemistry of Variscan dykes from the Jáchymov (Joachimsthal) ore district, Czech Republic

Popis výsledku v původním jazyce

Variscan dykes of kersantite, diorite to granodiorite porphyries, granite porphyries, spessartite and/or mafic-felsic composite dykes were studied in the Jáchymov ore district. Individual dyke of minette penetrates the OIC biotite granite outside the district. Lamprophyres and diorite porphyries occurring in an exocontact zone of the YIC granite pluton are affected by pervasive biotitization, locally by the joint-controlled greisenization. Geochemical data, petrography, petrophysical properties, and thestable isotope composition (O, C, S) are presented for 23 whole-rock samples. Bulk magnetic susceptibility of dyke rocks show a common descease from mafic to intermediate magmas due to the variations in magnetite content Local increase up to 5,000 . 10-6 [SI] refer to the presence of accessory pyrrhotite in some of the kersantite and diorite porphyry dykes. The magma mixing involving lamprophyric and felsic melts is suggested for diorite porphyrities.
