Este trabalho apresenta um modelo gravimétrico 2,5D gerado a partir de 315 novas estações gravimétricas levantadas ao longo uma seção transversal NW-SE com 750 km extensão na porção setentrional da Província Borborema, NE do Brasil. A modelagem gravimétrica foi aplicada separadamente nas componentes regional e residual campo gravitacional. das anomalias regionais revelou que profundidade interface crosta-manto varia 28 32 km, considerando densidade média 2,8 g/cm³ para crosta continental 3,3...

Gap fraction is a biophysical variable related to energy balance, forest fauna, micro-climate and regeneration, an important indicator of management quality. The objective this study was compare gap estimates from undisturbed forests different environments or strata selectively logged areas. Moreover, measurements were collected with two distinct instruments (optical canopy analyzer LAI-2000 hemispherical photographs). Field data sustainable sites at Jamari National Forest, Rondonia State,...

The origin and control of Uranium occurrences deposits at the Uraniferous District Lagoa Real, State Bahia (Brazil), has been largely studied over last decades. Currently, deposit controls are bounded to albitites in Granite-Gneissic Complex center-south area Real. Data from Sao Timoteo Airborne Geophysical Project have analyzed superimposed geological, geophysical remote sensing data order identify new for prospection. Reappraisal gammaspectrometric (K, U e Th) shows that distinctive...

Two 800 km long geophysical transects have been carried out in the Precambrian Borborema Province NE Brazil. A vast set of magnetotelluric, deep seismic refraction, gravity and magnetic data acquired since 2005. In this paper, we present a preliminary 2.5D modeling these transects, constrained by refraction geological information. The final models reveal very heterogeneous continental lithosphere beneath Province, result important tectonic events Neoproterozoic Cretaceous times.

Dimension Stones are an increasingly valuable commodity in Brazil, generating export revenues estimated to reach US$ 355 million in 2002. The proposed federal government target is to increase this amount over 600 within four years. To end, better exploration techniques will have be applied in order renew and replenish stocks. use of GIS-based can improve vectoring as well speed up the discovery process. A three-phase approach was considered, consisting digital processing (image generation,...

Abstract. By means of the multitemporal approach, we analyze changes in land use and vegetation cover São Francisco do Sul Itapoá municipalities, located northern coast State Santa Catarina, Brazil. LANDSAT satellite images from 1991 to 2019 were analyzed classified into four classes soil occupation (vegetated area, bare soil, urbanized water body) by GEOBIA method. Weighted sum analysis was applied ‘urbanized area’ class data available on geologic units, so as identify areas vulnerable...
