Evolución geomorfológica de la planicie lodosa de La Macolla, Península de Paraguaná, Estado Falcón, Venezuela Sara Lara Luis Felipe González Ciencias de la Tierra manglar Lagunas costeras terrazas marinas planicies lodosas transgresión holocénica El área de La Macolla se localiza al SW del faro homónimo en la costa NW de Paraguaná, Estado Falcón,Venezuela. El objetivo del trabajo es abordar una posible explicación de evolución geomorfológica, a partir de los indicadoresdisponibles en el campo, tales como terraza marina, manglar y barrera o cordón litoral, además de caracterizarlos ambientes sedimentológicos distintivos. Se trata de una antigua bahía bordeada por un escarpe de terraza constituidopor calizas fosilíferas con un promedio de altura de 80 cm. Este escarpe domina un área de 9.6 ha de planicie lodosao mud flat y una barrera litoral de 3.5 ha. La fracción limosa predominante en los sedimentos de la planicie lodosa ydel área de manglar se interpretan como evidencias de condiciones más húmedas que las actuales, que permitieron lameteorización de las calizas circundantes, una escorrentía superficial y el consiguiente transporte hasta las partes másbajas, donde la vegetación halófita se instaló. La evolución de la bahía a llanura cenagosa se atribuye a fluctuaciones delnivel marino y al cierre de cordones litorales por transporte sedimentario. 2007 artículo científico 0188-4611 https://www.redalyc.org/articulo.oa?id=56906202 es http://www.redalyc.org/revista.oa?id=569 Investigaciones Geográficas (Mx) application/pdf Universidad Nacional Autónoma de México Investigaciones Geográficas (Mx) (México) Num.62
