Fue aprobado por la Asamblea General del CGMW celebrada en Oslo (Noruega) durante el 33\u00ba Congreso Geol\u00f3gico Internacional.<\/p>\n<p>Esta tercera versi\u00f3n ha sido elaborada con la colaboraci\u00f3n de la Asociaci\u00f3n de Servicios Geol\u00f3gicos y Mineros Iberoamericanos (ASGMI), los Servicios Geol\u00f3gicos de Argentina, Brasil, Chile, Colombia, Ecuador, Per\u00fa y Uruguay, as\u00ed como varias universidades e institutos de investigaci\u00f3n adicionales mencionados en la informaci\u00f3n de los colaboradores.<\/p>\n<p>El Subcomit\u00e9 de <strong>Mapa geol\u00f3gico de Am\u00e9rica del Sur <\/strong>adopt\u00f3 una metodolog\u00eda que integraba la informaci\u00f3n geol\u00f3gica de cada pa\u00eds de la siguiente manera. En primer lugar, se gener\u00f3 un nuevo c\u00f3digo para cada unidad cronoestratigr\u00e1fica seg\u00fan la leyenda propuesta, utilizando capas digitales proporcionadas por los servicios geol\u00f3gicos de cada pa\u00eds.<\/p>\n<p>En segundo lugar, la simbolog\u00eda y los colores se crearon con patrones representativos de los tipos de roca y colores correspondientes a las edades.<\/p>\n<p>Por \u00faltimo, se prepar\u00f3 un mapa con unidades codificadas a escala 1:5 M.<\/p>\n<p>Para generalizar y relacionar las unidades a mano, se imprimi\u00f3 la GMSA a escala 1\/3 M con la nueva codificaci\u00f3n. A continuaci\u00f3n, se digitaliz\u00f3 y georreferenci\u00f3 la GMSA para generalizar las unidades geol\u00f3gicas, las fallas y los pliegues a escala 1:5M.<\/p>\n<p>Una vez hecho esto, y a pesar de la peque\u00f1a escala del mapa, las unidades cronoestratigr\u00e1ficas, fallas y pliegues del mapa se ajustaron utilizando im\u00e1genes de relieve sombreado (NASA STRM) para mejorar la correspondencia entre el relieve y las unidades geol\u00f3gicas cartografiadas.<\/p>\n<p>Por \u00faltimo, se ha armonizado la geolog\u00eda entre pa\u00edses. Cabe se\u00f1alar que la actualizaci\u00f3n de la GMSA se ha llevado a cabo consultando art\u00edculos publicados indexados internacionalmente.<\/p>\n<p>En <strong>Mapa geol\u00f3gico de Am\u00e9rica del Sur<\/strong> se basa en una proyecci\u00f3n polic\u00f3nica (latitud \u00d7 longitud), centrada en el meridiano -59\u00b0, datum WGS - 1984.<\/p>\n<p>Los datos de alta mar se extrajeron del Mapa Tect\u00f3nico de Sudam\u00e9rica a escala 1\/5,9M (Cordani et al., 2016);
