Abstract

This study covers a detailed stratigraphy, microfacies analysis and depositional history of the Middle–Upper Jurassic succession in the central part of the Taurides Carbonate Platform (TCP), southern Turkey (Kıraç Mountain, west of Central Taurides). The succession is subdivided into four units (Unit-1–Unit-4) and nine microfacies (MF1–MF9) are distinguished. Based on microfacies three depositional facies belts are determined and the depositional history of the platform part is explained. The Aalenian is represented by occasionally sandy, oolitic limestones (Unit-1), which indicate predominantly high-energy platform edge environmental conditions (shoal facies belt). The Bajocian–Kimmeridgian?/Tithonian? is represented by limestones with occasionally interlayered dolomite–dolomitic limestones (Unit-2–Unit-3), which are dominated by inner platform conditions (lagoon facies belt). During the Late Jurassic (Кimmeridgian?/Tithonian?)–Early Cretaceous (Berriasian) a significant environmental change occurred, recording a rapidly occurring platform drowning event. This period is represented by dolomite–dolomitic limestone–limestone (Unit-4) containing interlayers of ammonite, radiolarite, laminated limestone, mudstone, and limestone blocks that indicate an open shelf environment (open-marine facies belt). The Middle–Upper Jurassic carbonate succession in Kıraç Mountain has characteristics similar to other parts of the Taurides Carbonate Platform. However, it differs in that it contains Unit-4 characterizing the open shelf environment in the latest Jurassic–earliest Cretaceous.

克拉奇山（土耳其南部陶里德山脉中西部）中-上侏罗世地台碳酸盐岩演替的地层学和沉积史

摘要本研究涵盖了土耳其南部陶里德斯碳酸盐地台（TCP）中部（陶里德斯中部以西的 Kıraç 山）中-上侏罗世演替的详细地层、微地层分析和沉积历史。该演替被细分为四个单元（Unit-1-Unit-4）和九个微地层（MF1-MF9）。根据微岩相确定了三个沉积面带，并解释了平台部分的沉积历史。阿伦纪的代表是偶尔含沙的鲕粒灰岩（单元 1），表明主要是高能平台边缘环境条件（浅滩面带）。巴约纪-基默里吉纪/提托尼纪以灰岩为代表，偶尔夹白云岩-鲕粒灰岩（单元-2-单元-3），主要是内平台环境（泻湖面带）。在晚侏罗世（Кimmeridgian?/Tithonian?）-早白垩世（Berriasian）期间，环境发生了重大变化，记录了快速发生的平台淹没事件。这一时期的代表是白云岩-白云质石灰岩-石灰岩（单元-4），其中含有芒硝、放射虫、层状石灰岩、泥岩和石灰岩块的夹层，显示了一个开放的陆架环境（开放海相带）。Kıraç 山中上侏罗世碳酸盐岩演替的特征与陶里德斯碳酸盐岩地台的其他部分相似。然而，它的不同之处在于其中的单元-4 表明了晚侏罗世-早白垩世开放陆架环境的特征。

期刊介绍： Stratigraphy and Geological Correlation is the only journal that provides comprehensive coverage of the fundamental and applied aspects of stratigraphy and the correlation of geologic events and processes in time and space. Articles are based on the results of multidisciplinary studies and are for researchers, university professors, students, and geologists interested in stratigraphy and the chronological features of the world’s geological record.
