We report a preliminary rock-magnetic and microwave paleointensity study of historic lava flows between 1943 and 1948 of Paricutín volcano. These lava flows show well-preserved, well-exposed, fresh and extensive outcrops. Most samples are characteri

SUMMARY The San Quintin volcanic field (SQVF) in Baja California (Mexico) consists of at least 13 volcanic complexes with about 30 lava flows. 40Ar/39Ar step-heating and 3He surface exposure dating experiments suggest eruption ages between 22 and 165

We present new palaeointensity and palaeodirectional results from the Matuyama–Brunhes geomagnetic field reversal. Volcanic sequences from La Palma and Guadeloupe record the Matuyama–Brunhes boundary, possible precursors, and fluctuations in the

Following a detailed radioisotropic dating and palaeomagnetic investigation of transitional polarity lava flows of the Tatara-San Pedro volcanic complex (36°S, 71°W), in the Quebrada Turbia valley, Central Chile ( Brown et al., 2004 ), palaeointens

SUMMARY A single lava flow from the earliest eruption period (ca AD 1759-1774) of the Jorullo vol- cano, Michoacan-Guanajuato volcanic field (MGVF), Mexico has been sampled to determine the palaeointensity of the magnetic field at the time of extrusi

Absolute palaeointensity results were obtained from 392 samples (166 of 241 flows) from the upper 779 m of the Scientific Observation Hole 1 (SOH1) basalt core, Kilauea volcano, Hawaii, using the microwave palaeointensity technique. Based on K–Ar d
