LA-ICP-MS U-Pb apatite dating of Lower Cretaceous rocks from teschenite-picrite association in the Silesian Unit (southern Poland)

Autor: Krzysztof Szopa, David Chew, Roman Włodyka

Publikováno v: Geologica Carpathica, Vol 65, Iss 4, Pp 273-284 (2014)

The main products of volcanic activity in the teschenite-picrite association (TPA) are shallow, sub-volcanic intrusions, which predominate over extrusive volcanic rocks. They comprise a wide range of intrusive rocks which fall into two main groups: a
