Revista del Instituto de Investigación de la Facultad de Minas, Metalurgia y Ciencias Geográficas, 2016 Las muestras en estudio fueron extraídas a lo largo de la ribera de la laguna de Yantac-Junín, siendo uno de los objetivos identificar los minerales contaminantes procedentes de la actividad humana (ganadera, agrícola, etc.) y otros.Biviano Miramira, Luis Vilcapoma, Javier Jacay +2 moredoaj +1 more sourceSedimentos Relíquias na Plataforma Continental Brasileira
Pesquisas em Geociências, 1978 O estudo de sedimentos relíquias, ocorrentes em plataforma continental, tem contribuído para a compreensão de sua evolução paleogeográfica Quaternária e para o desenvolvimento de trabalhos de caráter econômico e aplicado. Na plataforma continental Brasileira, os estudos realizados, permitiram sua identificação, mapeamento e conhecimento de suas ...MARTINS, I.R., MARTINS, L.R., URIEN, C.M. +2 moreopenaire +2 more sourcesInfluence of marine and continental processes on the dynamics of a sand-ridge at the mouth of the Mafaguaqu river (Caraguatabuba - SP): preliminary conditions</a> </p><span class="r_subtitle"><img src="/img/openaccess.ico" alt="open access: yes" title="open access: yes" width="16" height="16"><i>Brazilian Journal of Oceanography</i>, 1983 </span><br><span class="r_content">This paper deals with the sedimentation and erosion dynamics of a sand-ridge on the Maçaguaçu River mouth on the São Paulo coastal plain, north of Caraguatatuba Bay.
