【话题·导语】
澳大利亚一个潜在的370 英里宽的陨石坑，被称为MAPCIS，可能会重塑我们对地球地质历史的理
解。研究人员发现了地质证据，包括震惊的矿物和融化的岩石，表明埃迪卡拉纪末期发生了巨大的撞击。

Massive 370-Mile Crater Discovery Challenges Existing Geological Theories
（文章来源：Sci Tech Daily）
Research team is delving into history, exploring events
that occurred hundreds of millions of years ago.
A potential crater over 370 miles (600 kilometers) wide
in central Australia may transform our knowledge of
Earth’s geological past.
Researcher Daniel Connelly and Virginia Commonwealth
University’s Arif Sikder, Ph.D., believe they have found evidence to support the existence of MAPCIS
– the Massive Australian Precambrian-Cambrian Impact Structure – which is a nonconcentric complex
crater that could provide new insights into the geological and biological evolution of our planet.
“Working on the MAPCIS project has been an incredible journey,” said Sikder, an associate
professor in the Center for Environmental Studies, a unit of VCU Life Sciences. “The data we’ve
gathered offers a unique glimpse into the forces that have shaped our planet, and I’m excited about the
future research this discovery will inspire.
This September, Connelly will make a presentation in Anaheim, California, at Connects 2024, the
Geological Society of America’s annual meeting. In August, he presented at the 37th International
Geological Congress 2024 in Busan, South Korea. According to researchers, the impact occurred at the
end of the Ediacaran period, within the Neoproterozoic Era, which spans from 1 billion to 538.8 million
years ago.
Geological Evidence of the Impact
Among the geological evidence they have uncovered to support the age, size, and location of the
impact are massive deposits of pseudotachylite breccia, or melt rock, near the crater center. The
researchers found shocked minerals, including lonsdaleite, or shocked diamond, in the deposits, along with
impact level amounts of iridium.
“The discovery of MAPCIS is a testament to the power of collaborative research,” Connelly said.
“Our findings not only highlight the significance of this impact structure but also open new avenues for
understanding Earth’s geological past.”

澳大利亚惊现370 英里陨石坑
研究小组正在深入研究历史，探索数亿年前发生的事件。
澳大利亚中部一个超过370 英里（600 公里）宽的潜在火山口可能会改变我们对地球地质历史的认
识。
研究员Daniel Connelly 和弗吉尼亚联邦大学的Arif Sikder 博士认为，他们已经找到了支持MAPCIS
存在的证据——澳大利亚前寒武纪-寒武纪大规模撞击结构——这是一个非中心的复杂陨石坑，可以为我们
星球的地质和生物进化提供新的见解。
“参与MAPCIS 项目是一段令人难以置信的旅程，”弗吉尼亚州立大学生命科学系环境研究中心的副
教授Sikder 说。“我们收集的数据提供了对塑造我们星球的力量的独特一瞥，我对这一发现将激发的未来
研究感到兴奋。
今年9 月，康奈利将在加利福尼亚州阿纳海姆举行的美国地质学会年会Connects 2024 上发表演讲。8
月，他在韩国釜山举行的2024 年第37 届国际地质大会上发表了演讲。据研究人员称，这次撞击发生在埃
迪卡拉纪末期，即新元古代，距今10 亿年至5.388 亿年。
撞击的地质证据
在他们发现的支持撞击年龄、大小和位置的地质证据中，有火山口中心附近的假速石角砾岩或熔融岩
石的大量沉积物。研究人员在矿床中发现了冲击矿物，包括朗斯代尔石或冲击钻石，以及冲击水平的铱。
康奈利说：“MAPCIS 的发现证明了合作研究的力量。”“我们的发现不仅突显了这种撞击结构的重
要性，也为理解地球的地质历史开辟了新的途径。”
