摘要

本文是对Singh et al. （Geological Journal, 2024:1-20）关于印度西部Kutch盆地渐新世-中新世海相沉积序列锶同位素地层学的评述。库奇拥有印度一些岩石地层和年代地层单位的层型。在本研究中，研究地层的sr同位素估计年龄与基于生物地层学的已知年龄有明显偏差。作者没有用生物地层学来验证解释的年龄。我们认为，严谨的样品筛选和生物地层学对sr同位素数据的验证是sr同位素地层学的两个基本要求。不幸的是，Singh等人对Kutch地层学的新贡献不能满足这两个条件，导致印度区域年代地层单位的年龄不正确。

This is a comment on the paper of Singh et al. (Geological Journal, 2024:1–20) on Strontium isotope stratigraphy of marine Oligocene–Miocene sedimentary successions of Kutch Basin, western India. Kutch hosts stratotypes of some lithostratigraphic and chronostratigraphic units of India. In this study, the Sr-isotope estimated ages of the studied formations deviate significantly from their known ages based on biostratigraphy. The authors have not validated the interpreted ages with biostratigraphy. We believe a scrupulous screening of samples and validation of Sr-isotope data with biostratigraphy are two essential requirements of Sr-isotope stratigraphy. Unfortunately, Singh et al. made a new contribution to Kutch stratigraphy that falls short of meeting both conditions, leading to incorrect ages of the regional chronostratigraphic units of India.

期刊介绍： In recent years there has been a growth of specialist journals within geological sciences. Nevertheless, there is an important role for a journal of an interdisciplinary kind. Traditionally, GEOLOGICAL JOURNAL has been such a journal and continues in its aim of promoting interest in all branches of the Geological Sciences, through publication of original research papers and review articles. The journal publishes Special Issues with a common theme or regional coverage e.g. Chinese Dinosaurs; Tectonics of the Eastern Mediterranean, Triassic basins of the Central and North Atlantic Borderlands). These are extensively cited. The Journal has a particular interest in publishing papers on regional case studies from any global locality which have conclusions of general interest. Such papers may emphasize aspects across the full spectrum of geological sciences.
