BRAZILGEO INFORMATION SYSTEMGEOLOGICAL MAPA digital map of Brazil 1:1 Mio was compiled during the last years in the largest geoscience project in GIS environment ever realized in Brazil. It unites the data available at the end of 2003 and allows a selection of topographic, geological, and ...
The initiatives to make geological heritage inventories in Brazil began to arise only a few decades ago, in part due to the large extension of the national territory, to the country’s heterogeneous geological knowledge and, often, to the lack of public policies. The first Brazilian attempt to...

Figure 4.Geological map of the Omai gold deposit 下载:全尺寸图片幻灯片 欧迈金矿围岩主要为镁铁质火山岩,其底部为多源砾岩,顶部为细粒沉积岩(图 4)。火山岩被长英质斑岩、流纹岩脉和欧迈花岗岩岩株侵入,后期被镁铁质岩脉和岩床切断。火山岩主要由块状或枕状拉斑玄武岩和钙碱性安山岩组成。长英质斑岩脉沿维...
The algorithm is illustrated on several incomplete data sets made of three to six two-dimensional seismic lines extracted from a three-dimensional seismic image located in the Santos Basin, offshore Brazil. In all cases, the simulation method generates a large number of plausible fault networks, ...
In Brazil, the ‘Itacaiunas Basin Geochemical Mapping and Background Project’ (ItacGMBP) regional mapping programme has been used for mineral exploration and to assess environmental contamination (Salomão et al., 2020), and in west-central Nigeria the ‘Nigerian Geochemical Mapping Technical ...
