摘要
利用 y k Menderes地堑(BMG)的附属盆地Söke-Milet (SMB)的沉积学特征和年代学资料，对土耳其西海岸第四纪进行了研究。在这里，我们首次从地质年代学上记录了fevzipa组(SMB的盆地填充单元)早更新世浅海扇三角洲序列，该组位于当前爱琴海海岸内陆15公里处，海拔150米。该地层在BMG的西端露头。包括冲积扇-淡水碳酸盐岩、浅海扇-三角洲和以基底内不整合面分隔的冲积扇沉积包体。根据常规沉积资料，在fevzipa组中划分出7种不同的相组合(FA):(FA 1)下冲积扇高流速沉积，(FA 2)淡水湖相碳酸盐岩沉积，(FA 3)前三角洲沉积，(FA 4)浅海扇三角洲斜坡沉积，(FA 5)近岸砂质河口坝式扇三角洲前缘沉积，(FA 6)冲积扇三角洲顶部沉积，(FA 7)上冲积扇高流速沉积。下部冲积扇沉积之上的浅海相，结合地层观测、地质年代学和古生物学年龄资料，表明爱琴海地区受到早更新世晚期海侵的影响。
Tectono-sedimentary evolution of an Early Pleistocene shallow marine fan-deltaic succession at the western coast of Turkey
The Quaternary period on the western coast of Turkey is studied using sedimentological features and geochronological age data of the Söke-Milet Basin (SMB), which is a subsidiary to the Büyük Menderes Graben (BMG). Here, for the first time, we geochronologically document the Early Pleistocene shallow marine fan-deltaic succession in the Fevzipaşa Formation (basin-fill unit of the SMB), 15 km inland of the current Aegean coast and 150 m above current sea level. The formation outcrops at the western end of the BMG. It comprises an alluvial fan to freshwater carbonate, shallow marine fan-deltaic and alluvial fan depositional packages separated by intrabasinal unconformities. Based on conventional sedimentary data, seven different facies associations (FA) have been distinguished in the Fevzipaşa Formation: (FA 1) hyperconcentrated flow-generated lower alluvial fan deposits, (FA 2) freshwater lacustrine carbonate deposits, (FA 3) prodelta deposits, (FA 4) shallow marine fan-delta slope deposits, (FA 5) nearshore sandy mouth-bar-type fan-delta front deposits, (FA 6) alluvial fan-delta top deposits and (FA 7) hyperconcentrated flow-generated upper alluvial fan deposits. The shallow marine facies above the lower alluvial fan deposits, considered in conjunction with stratigraphical observations and geochronological and paleontological age data, suggest that a late Early Pleistocene transgression affected the Aegean region.
期刊介绍：
Geodinamica Acta provides an international and interdisciplinary forum for the publication of results of recent research dealing with both internal and external geodynamics. Its aims to promote discussion between the various disciplines that work on the dynamics of the lithosphere and hydrosphere. There are no constraints over themes, provided the main thrust of the paper relates to Earth''s internal and external geodynamics. The Journal encourages the submission of papers in all fields of earth sciences, such as biostratigraphy, geochemistry, geochronology and thermochronology, geohazards and their societal impacts, geomorphology, geophysics, glaciology, igneous and metamorphic petrology, magmatism, marine geology, metamorphism, mineral-deposits and energy resources, mineralogy, orogeny, palaeoclimatology, palaeoecology, paleoceanograpgy, palaeontology, petroleum geology, sedimentology, seismology and earthquakes, stratigraphy, structural geology, surface processes, tectonics (neoteoctonic, plate tectonics, seismo-tectonics, Active tectonics) and volcanism.
Geodinamica Acta publishes high quality, peer-reviewed original and timely scientific papers, comprehensive review articles on hot topics of current interest, rapid communications relating to a significant advance in the earth sciences with broad interest, and discussions of papers that have already appeared in recent issues of the journal. Book reviews are also included. Submitted papers must have international appeal and regional implications; they should present work that would be of interest to many different specialists. Geographic coverage is global and work on any part of the world is considered. The Journal also publishes thematic sets of papers on topical aspects of earth sciences or special issues of selected papers from conferences.
