摘要

我们对巴基斯坦东北部苏尔加尔山脉(Baroch Nala 段)暴露较好的上古新世-下新世地层演替进行了综合、高分辨率的生物地层学、矿物学和地球化学鉴定。Baroch Nala 段的动物群落以透明底栖有孔虫和绿色钙质藻类为主,并含有大量陆生部分和陆源有机质,证明该段沉积于低能量的浅海环境中。这样的环境条件加上微弱的成岩作用,使我们能够将碳稳定同位素的连续记录与碳酸盐生成集合体生物反应的详细说明、基于粘土矿物的古气候信息以及基于汞浓度的火山活动信息结合起来。研究清楚地记录了从晚古新世到古新世始新世热极盛期(PETM)的环境演变,包括 PETM 之前较弱的温暖偏移(即 "POE"),以及大型底栖有孔虫群的演变。总体记录完美地展示了底栖碳酸盐生产者的更替是如何从 PETM 开始,到偏移结束时完成的,突出了(地质学上的)短暂环境振荡如何对生物圈产生长期持久的影响。

The Baroch Nala section (NE Pakistan): A new PETM standard for the eastern Tethys
We present an integrated, high-resolution, biostratigraphical, mineralogical, and geochemical characterization of the well-exposed Upper Paleocene - Lower Eocene stratigraphic succession of the Surghar Range (Baroch Nala section, NE Pakistan). The faunal assemblages from the Baroch Nala section, dominated by hyaline benthic foraminifera and green calcareous algae, along with the significant terrigenous fraction and the presence of terrestrially derived organic matter, testify to the deposition in a low-energy shallow-marine environment. Such environmental conditions, coupled with weak diagenetic effects, allow us to integrate a continuous record of carbon stable isotopes with a detailed account of the biotic response by carbonate-producing assemblages, paleoclimatic information based on clay-minerals, and information on volcanic activity based on mercury concentrations. The environmental evolution from the Late Paleocene up to the Paleocene Eocene Thermal Maximum (PETM) is clearly documented, including the weaker warm excursion that precedes the PETM (i.e. the Pre-Onset Excursion “POE”), and the evolution of large benthic foraminiferal assemblages. The overall record perfectly shows how the turnover in benthic carbonate producers started with the onset of the PETM and was completed by the time the excursion ended, highlighting how (geologically) brief environmental oscillations can have long lasting effects on the biosphere.

期刊介绍: Marine and Petroleum Geology is the pre-eminent international forum for the exchange of multidisciplinary concepts, interpretations and techniques for all concerned with marine and petroleum geology in industry, government and academia. Rapid bimonthly publication allows early communications of papers or short communications to the geoscience community. Marine and Petroleum Geology is essential reading for geologists, geophysicists and explorationists in industry, government and academia working in the following areas: marine geology; basin analysis and evaluation; organic geochemistry; reserve/resource estimation; seismic stratigraphy; thermal models of basic evolution; sedimentary geology; continental margins; geophysical interpretation; structural geology/tectonics; formation evaluation techniques; well logging.
