Palaeomagnetism and 40Ar/ 39Ar dating from Lower Jurassic rocks in Gastre, central Patagonia: Further data to explore tectonomagmatic events associated with the break-up of Gondwana
New 40Ar/ 39Ar data indicate ages of c. 185 Ma for the Lonco Trapial volcanic field in Gastre, north-central Patagonia, implying that this andesitic unit is roughly coeval with the Marifil silicic province that crops out in the eastern part of northern Patagonia.
