THE 1590-1520 MA CACHOEIRINHA MAGMATIC ARC AND ITS TECTONIC IMPLICATIONS FOR THE MESOPROTEROZOIC SW AMAZONIAN CRATON CRUSTAL EVOLUTION

The 1590-1520 Ma Cachoeirinha magmatic arc and its tectonic implications for the Mesoproterozoic SW Amazonian craton crustal evolution

Isotopic and chemical data of rocks from the Cachoeirinha suite provide new insights on the Proterozoic evolution of the Rio Negro/Juruena Province in SW Amazonian craton.Six U-Pb and Sm-Nd analyses in granitoid rocks of the Cachoeirinha suite yielded ages of 1587-1522 Ma and T DM model ages of 1.88-1.75 Ga (EpsilonNd values of -0.8 to +1.0).In add

RRAT J1913+1330: An Extremely Variable and Puzzling Pulsar

Rotating radio transients (RRATs) are neutron stars that emit sporadic radio bursts.We detected 1955 single pulses from RRAT J1913+1330 using the 19 beam receiver of the Five-hundred-meter Aperture Spherical radio Telescope.These pulses were detected in 19 distinct clusters, with 49.4% of them occurring with a waiting time of one rotation period.Th
