Autor: Ely Brasil de Arruda Luna Cavalcanti, José De Araújo Nogueira Neto, Eldemar De Albuquerque Menor, Adejardo Francisco Da Silva Filho, Marcelo Reis Rodrigues Da Silva, Lucas Fontenele Amorim

Publikováno v: Anuário do Instituto de Geociências. 46

A number of “black granites” were tested using simulated acidic weathering (H2SO4, HNO3, H2SO4/HNO3 and HCl, at pH = 3,00), freeze resistance and relative loss of brightness. The same plates of these granites remained immersed in each acidic solu

Upper Pleistocene–Holocene in the continental slope of the Cará Basin: an integrated analysis based on planktic foraminifera, sedimentological and geochemical aspects

Autor: Robbyson Mendes Melo, Eldemar de Albuquerque Menor, George Satander Sá Freire, Agathe Arrissa Noucoucouk

Publikováno v: Revista Brasileira de Paleontologia. 24:179-194

This research addresses paleoclimatic variations using sedimentological, geochemical, and planktic foraminifera. The study was carried out in a survey core (ANP 1011) collected on the continental slope of the Icarai Sub-basin (Ceara Basin), on the co

This paper presents a method based on hydrogeochemical signatures for the identification of flow com- ponents, from the descending limb to the baseflow, without the direct support of hydrographs. The pro- posed model was built using chemical analysis

Ancient Coastlines in the Continental Shelf of the State of Ceará, Northeast Brazil: Evidence from Sediment Chemistry and Stable Isotopes

Autor: Wanessa Sousa Marques, Roberto Lúcio Belo de Souza, Valderez P. Ferreira, Eldemar de Albuquerque Menor, Alcides N. Sial, George Satander Sá Freire, Enjolras de Albuquerque Medeiros Lima

Publikováno v: International Geology Review. 50:1141-1156

Continental shelf sediments from the state of Ceara, northeastern Brazil, have been studied to investigate meteoric diagenesis of marine sediments of previously defined ancient coastal lines. Major elements for 131 samples of carbonate sediments and
