Morphostructural analysis of the hydrographic basins of Sabana and Papagayo rivers (middle-lower third), Guerrero State, Mexico
This study presents the morphostructural patterns of the lower parts of the Papagayo and Sabana river basins, formed during the neotectonic (N-Q) stage. The structural framework consists of positive and negative blocks, which inherited their internal structure from different lithologic complexes and...

Morphostructural analysis of the hydrographic basins of Sabana and Papagayo rivers (middle-lower third), Guerrero State, MexicoAnálisis morfoestructural de las cuencas hidrográficas de los ríos Sabana y Papagayo (tercio medio-inferior), estado de Guerrero, MéxicoHernández Santana, José RamónOrtis Pérez, Mario ArturoMorphostructurestructural-geomorphological cartographyMorfoestructuracartografía estructuro-geomorfológicaThis study presents the morphostructural patterns of the lower parts of the Papagayo and Sabana river basins, formed during the neotectonic (N-Q) stage. The structural framework consists of positive and negative blocks, which inherited their internal structure from different lithologic complexes and from older phases of tectonic deformation. The morphostructures can be distinguished, among others: massive, on granite basement; blocks on folds and monoclinals, on terrigenous and calcareous rocks; chaotic, on gravitational deposits; unconsolidated, on young deposits; and others types. Neotectonics has acted differentially, determining diverse faulting styles. The designs of granitic and metamorphic foliations are superimposed on those styles, as a tectonically passive expression of lithology. Finally, the study found 32 types of morphostructures, associated in several geotectonic communities of blocks, among others: irregular system of blocks; system of stepped triangular horst, deformed by transcurrent faults; isometric system of stepped blocks; alternate asymmetral system of horst and graben; system of stepped blocks on circular and annular structures; and others.En este trabajo se presentan las principales regularidades del plano morfoestructural de los tercios medio e inferior de las cuencas hidrográficas de los ríos Papagayo y Sabana, en el estado de Guerrero, el cual se formó durante la etapa neotectónica (N - Q) del desarrollo del relieve, en un diseño de bloques positivos y negativos, que han heredado la estructura interna de los diferentes complejos litológicos presentes y de sus deformaciones tectónicas antiguas, determinando la presencia de morfoestructuras masivas, sobre basamento granítico; morfoestructuras de bloques en plegamientos y monoclinales sobre rocas terrígenas y mantos calcáreos; morfoestructuras caóticas sobre depósitos gravitacionales; morfoestructuras en depósitos jóvenes no consolidados; y otros tipos. La neotectónica ha sido diferenciada, determinando diferentes ascensos durante la etapa que determinan un complicado mosaico de diversos estilos de fracturamiento, sobre los cuales se sobreponen los diseños de las foliaciones graníticas y metamórficas, como expresión tectónicamente pasiva de la litología. Finalmente, la tipología estructuro-geomorfológica arrojó la presencia de 32 tipos de morfoestructuras, ocho en montañas medias, ocho en montañas bajas, siete en premontañas, cuatro en lomeríos y cinco en llanuras, desarrolladas en cinco basamentos geológicos con cuatro niveles de expresión litomorfoestructural. Estos bloques morfoestructurales encuentran relación en varias comunidades geotectónicas de interrelación interbloques neotectónicos: sistema irregular de bloques; sistema de horst triangulares escalonados, en transcurrencias; sistema isométrico de bloques escalonados; sistema asimétrico alterno de horst y graben; sistema de bloques escalonados en litomorfoestructuras circulares; sistema de litomorfoestructuras circulares en bóveda; entre otros.Instituto de Geografía2012-02-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.investigacionesgeograficas.unam.mx/index.php/rig/article/view/3009310.14350/rig.30093Investigaciones Geográficas; No. 56; 7Investigaciones Geográficas; Núm. 56; 72448-72790188-4611reponame:Investigaciones Geográficasinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.investigacionesgeograficas.unam.mx/index.php/rig/article/view/30093/27971info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/300932024-11-05T15:50:28Z |
