The identified taxa show a wide stratigraphic range and have low biostratigraphic value. Two separate intervals are distinguished by their content in planktic elements. In both intervals palynologic associations are difficult to compare with other european basins. Recorded planktic taxa disappear at the Miiabile-Semicelatum Subzone transition (lower Toarcian).

El sistema aluvial que deposito los Conglomerados de Moraleda \u0000de Zafayona era el predecesor del Rio Cacin que, al contrario que \u0000hoy dia, dominaba sobre el Rio Genil en lo que a extension de sus \u0000depositos se refiere. \u0000El modelo fluvial de Moraleda de Zafayona esta formado por un \u0000valle aluvial elongado en direccion sur-norte que se incurva hacia el \u0000oeste cerca de la localidad que le da nombre (Fig. 2). En el valle se \u0000depositaban facies de llanura de inundacion y de relleno de canal. \u0000La tendencia al apilamiento de los canales en la misma vertical sugiere \u0000que la direccion del drenaje tiene un control tectonico. \u0000En los materiales depositados en la llanura de inundacion se pueden \u0000diferenciar dos asociaciones de facies acordes con la posicion del \u0000paleo-nivel freatico durante el deposito (Fig. 3): a) llanura de inundacion \u0000subaerea, con niveles de nodulos carbonatados debidos a rizocreciones, \u0000y b) llanura de inundacion subacuosa o encharcada (backswamp) \u0000con niveles de carbonatos con fauna de gasteropodos lacustres y niveles afectados por procesos hidromorficos. El tipo b) domina \u0000hacia el norte donde la subsidencIa es mayor, pero a lo largo del deposito \u0000se expandio en direccion sur. \u0000Las facies de relleno de canal se depositaron en un cauce que tenia \u0000partes activas e inactivas (Fig. 8) algo mas elevadas, cuya posicion variaba \u0000con el tiempo, generando una estructura interna compleja en la \u0000que puede reconocerse una megasecuencia granodecreciente constituida \u0000por Gms → Gm/Sh → Gt → St Fl (P) (Fig. 4). En los canales se formaban \u0000barras cuya evolucion sedimentaria generica incluye varias fases \u0000de erosion y deposito causadas por los altibajos de la descarga \u0000que quedan reflejados en las secuencias de varias escalas (Figs. 5, 6, 7). \u0000El nucleo de la barra se formo en condiciones de alta descarga y alta \u0000energia. Luego, durante gran parte de su historia, la barra iba ofreciendo \u0000un obstaculo cada vez mayor a la corriente y la disminucion de la \u0000profundidad causo condiciones de alta energia que no esta necesariamente \u0000relacionada con descargas elevadas. A partir de cierta altura, \u0000sin embargo, la barra se convirtio en un obstaculo demasiado elevado \u0000y el agua que la sobrepasaba se movia con poca velocidad a causa del \u0000rozamiento sobre el fondo, depositandose fracciones mas finas cada \u0000vez, que integran una secuencia granodecreciente superpuesta a la anterior. \u0000La preservacion de las partes altas de las secuencias es problematica, \u0000pues son las primeras en ser eliminadas si llega a producirse \u0000erosion posteriormente debido a la migracion de canales dentro del \u0000cauce mayor (Fig. 8). \u0000La arquitec","PeriodicalId":110220,"journal":{"name":"Journal of iberian geology: an international publication of earth sciences","volume":"528 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123361384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
