摘要

拉底统上侏罗统至下侏罗统扎特尼克组是中生代海相布莱德盆地的岩石地层单元。在朱利安阿尔卑斯山脉Pokljuka山高原的Zajamniki山牧场记录了Zatrnik组的最上部及其向上覆Ribnica角砾岩的过渡。剖面最下部为“经典”扎特尼克组,以米色泥晶灰岩和细粒方解岩为主。有孔虫有Siphovalvulina、Everticyclammina、Mesoendothyra和pseudoopfenderina,显示早侏罗世时代。米色石灰岩紧随其后的是最上层扎特尼克组的浅粉色石灰岩。在这个间隔中,滑坡很常见,海百合也很丰富。除了一些已经出现在较低演为层的物种外,在这个区间内还出现了Meandrovoluta asiagoensis Fugagnoli & Rettori, Trocholina sp., Valvulinidae,小型texulariidae, Lagenida和小型Ophthalmidium。再沉积灰岩在研究的Zatrnik组中占主导地位,表明沉积在盆地的斜坡上或斜坡脚下。Zatrnik组塌陷段向富海红相的转变可能反映了Pliensbachian朱利安碳酸盐岩台地边缘加速沉降。扎特尼克组之后是普林恩巴哈组(?)Ribnica角砾岩。氧化铁浸渍、紫色和粘土含量增加是其特征。有孔虫组合包括Lenticulina,小的细长Lagenida和epistominids。里布尼察角砾岩的个别层是通过泥石流沉积的。氧化铁的富集表明沉淀速度较慢。

Sedimentological and paleontological analysis of the Lower Jurassic part of the Zatrnik Formation on the Pokljuka plateau, Slovenia
The uppermost Ladinian to Lower Jurassic Zatrnik Formation is the lithostratigraphic unit of the Mesozoic deeper marine Bled Basin. The uppermost part of the Zatrnik Formation and the transition into the overlying Ribnica Breccia was logged at the Zajamniki mountain pasture on the Pokljuka mountain plateau in the Julian Alps. The lowermost part the section belongs to the “classical” Zatrnik Formation and is dominated by beige micritic limestone and fine-grained calcarenite. Foraminifers Siphovalvulina, ?Everticyclammina, ?Mesoendothyra and ?Pseudopfenderina are present, indicating Early Jurassic age. The beige limestone is followed by light pink limestone of the uppermost Zatrnik Formation. Slumps are common in this interval, and crinoids are abundant. Alongside some species already present in beds lower in the succession, Meandrovoluta asiagoensis Fugagnoli & Rettori, Trocholina sp., Valvulinidae, small Textulariidae, Lagenida, and small ?Ophthalmidium alsooccur in this interval. Resedimented limestone predominates through the studied part of the Zatrnik Formation, indicating deposition on the slope or at the foot of the slope of the basin. The switch to crinoid-rich facies within the slumped interval of the Zatrnik Formation may reflect accelerated subsidence of the margins of the Julian Carbonate Platform in the Pliensbachian. The Zatrnik Formation is followed by the formation of the Pliensbachian (?) Ribnica Breccia. Impregnations of ferromanganese oxides, violet colour, and an increase in clay content are characteristic. The foraminiferal assemblage consists of Lenticulina, small elongated Lagenida, and epistominids. Individual beds of the Ribnica Breccia were deposited via debris flows. Enrichments in ferromanganese oxides point to slower sedimentation.
