Stable carbon isotope chemostratigraphy of the base of the Callovian in Greenland Gondwana Res. (IF 7.2) Pub Date : 2024-08-31 Ricardo L. Silva, Peter Alsen
D’Orbigny named the Callovian stage after Kellaways in Wiltshire, UK, in the 1850 s. However, agreement on its boundaries and, more recently, on the position and location of the Global Boundary Stratotype Section and Point (GSSP) for the base of the Callovian has proven difficult for the last 170 years. This is mainly due to the lack of agreement on the appropriate index fossil and its regional and

Marine Fe cycling linked to dynamic redox variability, biological activity and post-depositional mineralization in the 1.1 Ga Mesoproterozoic Taoudeni Basin, Mauritania Gondwana Res. (IF 7.2) Pub Date : 2024-08-30 Mohamed Ghnahalla, Olivier Rouxel, Ernest Chi Fru, Olabode M. Bankole, Mohamed Salem Sabar, Ahmed Abd Elmola, Ibtissam Chraiki, Fatima Abdelfadel, Claude Fontaine, Alain Trentesaux, Rayane El Ghastalany, El Houssein Abdeina, Abderrazak El Albani
The concentration of redox sensitive trace metals (RSTEs) and their isotopic composition preserved in Precambrian marine sediments, are critical for the reconstruction of ocean–atmosphere oxygenation history. Particularly, the concentration of Fe, its redox speciation, and isotopic distribution, have gained widespread use for inferring the biogeochemical processes that controlled Fe cycling in Precambrian

Scheelite as a microtextural and geochemical tracer of multistage ore-forming processes in skarn mineralization: A case study from the giant Xintianling W deposit, South China Gondwana Res. (IF 7.2) Pub Date : 2024-08-30 Hongfei Di, Yong-Jun Shao, Yi-Qu Xiong, Han Zheng, Xiang Fang, Wenjie Fang
The Xintianling deposit is one of the largest skarn-type scheelite deposit in China. Recent discoveries of quartz-vein-type scheelite mineralization within the deposit have raised questions about its origin and the evolution of ore-forming fluids, hindering a comprehensive understanding of the ore-forming process. We investigate the microtextures, trace elements, and oxygen isotope compositions of

South Tibetan Detachment System (STDS), NW Himalaya: A possible Cambro–Ordovician tectonic terrane boundary, and its Cenozoic remobilization Gondwana Res. (IF 7.2) Pub Date : 2024-08-30 Gargi G. Deshmukh, A.K. Jain, P.K. Mukherjee, Saurabh Singhal, Rahul Dixit, D.C. Srivastava
The South Tibetan Detachment System is an important extensional fault zone, separating the Greater Himalayan Sequence from the overlying Tethyan Himalayan Sequence, and is well exposed in the upper reaches of the Dhauliganga valley, NW Himalaya. This fault system is characterized by the occurrence of an extensive Cambro–Ordovician granite belt between Sutlej and Dhauliganga valleys, although only a

Pollution level and distribution characteristics of heavy metals and microplastics in the soils from the Qionghai Lake Wetland, Southwest China Gondwana Res. (IF 7.2) Pub Date : 2024-08-29 Jinjin Wang, Zailin Chen, Xuemei Wang, Yanqun Wang, Huibin Shi, Yi Huang
Urban wetlands are reported to be ideal habitats for accumulation of HMs and MPs. However, study on combined pollution of HMs and MPs in soil is rare in urban wetland environment. In this study, the characteristics of HMs and MPs in the soils of the Qionghai Lake wetland in southwest China were studied by using ICP–MS, and FTIR. The results showed that the average concentration of HMs in soil ranges

A mid-Cretaceous carbon isotope reference curve for the SE Neo-Tethys region (Zagros, W Iran) Gondwana Res. (IF 7.2) Pub Date : 2024-08-27 Amin Navidtalab, Ulrich Heimhofer, Elaheh Zarei
Stable carbon isotope chemostratigraphy and the associated reference curves have proved to be valuable tools for stratigraphic calibration and long-distance correlations. Nonetheless, the reference curves covering the Cretaceous have mostly been produced from localities located within the W Neo-Tethys. In order to establish a reference curve for the SE Neo-Tethys margin, an Aptian–Albian hemipelagic

Discovery of mafic dikes in northeastern Tibet plateau belonging to the Emeishan large igneous province: Implications for paleocontinental reconstruction and mineral exploration Gondwana Res. (IF 7.2) Pub Date : 2024-08-24 Kang Yang, Wei-Guang Zhu, Chusi Li, Zhong-Jie Bai, Yan-Jun Wang, Shi-Ji Zheng, Peng-Cheng Hu
Due to the lack of paleomagnetic data and paleoclimatic records, the paleocontinental belonging of the Yidun terrane in northeastern Tibet plateau is debated. In this paper, we use the distribution of the Emeishan large igneous province (ELIP) to put the issue to rest. The ELIP is the product of mantle plume activity, which took place at 260 ± 3 Ma in the western margin of the Yangtze craton. The Yangtze
