Fifteen years after the initial detection of Rickettsia slovaca in ticks in Portugal, 3 autochthonous cases of R. slovaca infection were diagnosed in humans. All patients had an eschar on the scalp and lymphadenopathy; 2 patients had facial edema. R. slovaca infection was confirmed by serologic testing, culture, and PCR.
The detection of suboutcropping pegmatite deposits in regions recognizably fertile regarding the occurrence of pegmatites depends upon the optimization of conceptual models which support the interpretation of the regional distribution of pegmatites and the structure of their assemblies. In intra-granitic context is at concern the more conventional cartographic expression of pegmatites in connection with the str...
Exploration programs for granitic pegmatites face the lack of detectable contrasts, either geophysical or geochemical, between pegmatites and their granitic host-rocks. The known productive sectors bearing pegmatites located inside granitic plutons, with economic interest for quartz and feldspar provide adequate field testing for alternative research, dealing with the peculiarities of lithological diversity and...
"I Congresso Internacional de Geoci??ncias na CPLP" ; Em contexto de prospec????o de bolsadas pegmat??ticas hospedadas em granitos da regi??o de Ponte da Barca, procurou??????se, combinando t??cnicas de an??lise distanciada e levantamento de campo, detectar interfaces litol??gicas com as quais se pudesse relacionar a organiza????o espacial e estrutural dos pegmatitos a?? aflorantes. A evid??ncia de alinhamento...
