“…Also, an anomaly with the same feature with the anomalies of the ring complexes is also revealed by the overlain map (indicated with question marks) but without an associated surface manifestation (outcrop). This anomaly, bounded by longitude 8˚32'E and 8˚38'E and latitude 10˚32'N and10˚40'N, is believed to be an intrusion, probably a ring complex without a surface exposure, similar to that suggested by [9] in the north eastern part of the province and by [22]- [25] in central Brazil.…”

“…Tanto na base fixa como na estação itinerante, foram feitas medidas de temperatura com o bulbo dos termômetros seco e úmido, para o cálculo da umidade relativa do ar. A distribuição dos erros para esse método de medida tem como desvio padrão aproximadamente 0,5 m, representando menos de 0,2 mGal na medida de g (McLintock et al, 1994). Note-se que a incerteza na medida da altimetria, de muito supera as demais envolvidas no cálculo da propagação de erros.…”

“…Sua geometria em subsuperfície é muito semelhante às demais rochas alcalinas estudadas na área (Slavec et al, 2001;Rugenski et al, 2001;Mantovani et al, 2005). Nas imagens é visível a presença de diáclases (fraturas, juntas ou falhas no corpo alcalino sem deslocamento relativo das partes), bem como, o seu formato irregular na base, não apresentando um único duto como nos demais casos.…”

“…7 in Dutra & Marangoni, 2009) using ME geophysical response as a model. Mantovani et al (2005) made a geophysical survey integrating gravity, magnetic and shallow seismic refraction signals over a small magnetic anomaly, mapped in the aeromagnetic survey of the Ponta Grossa Arch Alkaline Province. They obtained a Bouguer gravity anomaly similar to others gravity anomalies correlated to mapped intrusions in the province.…”
