This paper presents a 3D seismic-based case study from the deep-water Niger Delta Basin to investigate sedimentary–tectonic interaction on growth sequence architecture within the thrust-related intraslope or piggyback basins. Gravitational contraction in the lower continental slope had yielded a series of thrust faults and associated folds in the study area, which formed several piggyback basins. These

Taenidium barretti ichnofabric and rainfall seasonality: Insights into dryland suites of Scoyenia ichnofacies J. Palaeogeogr. (IF 2.789) Pub Date : 2022-10-25 Diego Luciano Nascimento, Renata Guimarães Netto, Alessandro Batezelli, Francisco Sérgio Bernardes Ladeira, Daniel Sedorko
The present work analyzes the monotypic Taenidium barretti ichnofabric developed in abandoned channels and floodplains to understand its paleoecological significance in highly seasonal fluvial systems. The data come from the Cretaceous paleosols of the Marília Formation (Bauru Basin, SE Brazil), in which the T. barretti ichnofabric and rhizoliths represent the biotic record. Beetle larvae are considered

Petrological and geochemical characteristics of the Ordovician–Silurian black shale in eastern Sichuan and western Hubei, South China: Differential sedimentary responses to tectonism and glaciation J. Palaeogeogr. (IF 2.789) Pub Date : 2022-10-19 Quan-Sheng Cai, Ming-Yi Hu, Oumar Ibrahima Kane, Zhi Yang, Ya-Ru Wen, Qun Luo, Ming-Tao Li, Zhong-Gui Hu, Qing-Jie Deng
During the Ordovician–Silurian transition period, the Yangtze area experienced significant environmental changes, which were recorded by the widely distributed black shale of the Upper Ordovician Wufeng and Lower Silurian Longmaxi formations. However, the petrological and geochemical analyses of the Upper Ordovician-Lower Silurian black shale in Well JY1 (eastern Sichuan Basin) and Well YY2 (western

Northeastern Asia humidification at the end of the Miocene drives the boost of mammalian dispersals from the Old to New World J. Palaeogeogr. (IF 2.789) Pub Date : 2022-10-07 Qigao Jiangzuo, Shi-Qi Wang
Mammals have high dispersal ability, and many lineages can spread across the continents when a landbridge appears. Here, we summarize the dispersal of mammals between the Old and New World at the end of the Miocene. Our analysis suggested that the three phases of dispersal represented the largest dispersal tide during the Neogene, and the direction of dispersal is dominated by being from the Old to

First record of stable isotopes (δ13C, δ18O) and element ratios (Mg/Ca, Sr/Ca) of Middle to Late Jurassic belemnites from the Indian Himalayas and their potential for palaeoenvironmental reconstructions J. Palaeogeogr. (IF 2.789) Pub Date : 2021-08-30 Alberti, Matthias, Fürsich, Franz T., Pandey, Dhirendra K., Andersen, Nils, Garbe-Schönberg, Dieter, Bhosale, Suraj, Chaskar, Ketan, Habermann, Jörg M.
Middle to Late Jurassic belemnites from the Spiti and Zanskar valleys in the Indian Himalayas were used for stable isotope (δ13C, δ18O) and element (Mg/Ca, Sr/Ca) analyses. Although the Himalayan orogeny deformed and altered a large portion of the collected fossils, cathodoluminescence and scanning electron microscopy in combination with analyses of iron and manganese contents allowed the identification

Deltas: a new classification expanding Bates’s concepts J. Palaeogeogr. (IF 2.789) Pub Date : 2021-08-06 Zavala, Carlos, Arcuri, Mariano, Di Meglio, Mariano, Zorzano, Agustin, Otharán, Germán, Irastorza, Ainara, Torresi, Antonela
Deltas constitute complex depositional systems formed when a land-derived gravity-flow (carrying water and sediments) discharges into a marine or lacustrine standing body of water. However, the complexity of deltaic sedimentary environments has been oversimplified by geoscientists over the years, considering just littoral deltas as the unique possible type of delta in natural systems. Nevertheless

Manganese carbonate stromatolites of the Ediacaran Doushantuo Formation in Chengkou, northern Yangtze Craton, China J. Palaeogeogr. (IF 2.789) Pub Date : 2021-07-29 Zhang, Yi, Li, Jian, Chen, Long, Wei, Yi, Shi, Qiang, Wang, Dong-Ge, Wu, Qing-Ming, Song, Liao-Yuan, Tian, Meng, Kuang, Hong-Wei, Liu, Yong-Qing, Mänd, Kaarel, Bai, Hua-Qing, Liu, Zi-Liang, Wang, Yu-Chong, Qiao, Da-Wei, Zhu, Wen-Jun
The origin process of manganese ores remains unsolved worldwide. Exploring the origins of stromatolites that contain manganese may be a key to deciphering the sedimentary environments and metallogenic processes of these deposits. However, only a few manganese stromatolites have been discovered and described until now. Microbialites are well developed in the manganese deposits, located near the top

Spatiotemporal patterns of sediment deposition on the northern slope of the South China Sea in the last 150,000 years J. Palaeogeogr. (IF 2.789) Pub Date : 2021-07-28 Zhe Hu, Bao-Qi Huang, Le-Jun Liu, Na Wang
The source-to-sink system of the northern South China Sea (SCS) has been widely discussed during the past few decades. Sr–Nd isotope, clay minerals and trace elements were extensively used as the proxies of sediment provenance, however, still little is known about the transport processes and controlling mechanisms on detailed spatiotemporal scales due to the limitations of these methods. Here we put

Provenance of sediments from Barra del Tordo and Tesoro beaches, Tamaulipas State, northwestern Gulf of Mexico J. Palaeogeogr. (IF 2.789) Pub Date : 2021-07-28 Mayla A. Ramos-Vázquez, John S. Armstrong-Altrin
The mineralogy, bulk sediment geochemical composition, and U–Pb ages of detrital zircons retrieved from the Barra del Tordo (Tordo) and Tesoro beach sediments in the northwestern Gulf of Mexico were analyzed to determine their provenance. The beach sediments are mainly composed of quartz, ilmenite, magnetite, titanite, zircon, and anorthite. The weathering proxies such as the Chemical Index of Alteration
