ABSTRACT: A ground magnetic survey in a Central-East area of the Santa Catarina Island tested the continuity of the Cretaceous mafic dykes beneath the aeolic sediments of the Joaquina plain. Vertical gradient measurements taken in 1880 stations did n

Este trabalho apresenta uma visão da Geofísica no que diz respeito à algumas manifestações físicas que trazem informações sobre a estrutura interna da Terra. Desta forma, são abordados alguns conceitos básicos sobre sismologia, o estudo das

Paleomagnetic data is the only way to access the behavior of the geomagnetic field of internal origin through geological time. Therefore, the complete description of the paleosecular variation (PSV) is fundamental for unraveling the evolution of the

The existing relative paleointensity (RPI) database allowed the construction of reliable stacking curves for at least the last 1 Myr. Observed fluctuations in the RPI curves suggest both lithologic/climatic influence or geodynamo processes. Stacked p

The Parana Magmatic Province (PMP) in southern Brazil is divided into three sub-provinces historically characterized by their Ti content (low-Ti in the southern sub-province, high-Ti in the northern, and mixed in the central sub-province). Ar/Ar and

Irregularly sampled time series are common in several different areas, such as astronomy, meteorology, biology, oceanography, cyclostratigraphy, and others. The periodogram is a primary tool to extract meaningful information from irregularly spaced a

We present an analysis of the error involved in the so-called low induction number approximation in the electromagnetic methods. In particular, we focus on the EM34 equipment settings and field configurations, widely used for geophysical prospecting
