苏格兰西海岸717亿年前的岩石是地球第一个冰河时代(“雪球地球”)的参照点。 717-million-year-old rocks in Scotland's west coast offer a reference point for Earth's first ice age ("snowball Earth").
科学家们在苏格兰西海岸外的加尔韦拉奇斯发现了独特的岩石, 这可能是地球第一个冰河时代的参照点, 被称为“雪球地球”, 大约在7亿1700万年前。 Scientists have found unique rocks on the Garvellachs, off Scotland's west coast, that may serve as a reference point for Earth's first ice age, known as "snowball Earth," approximately 717 million years ago. 这一发现包括沉积岩,其中含有日期为Zircons的沉积岩,有助于为冷冻期间建立一个全球边界斯特拉托型区块和点(GSSP),标志着复杂生命和多细胞生物的重大发展。 This discovery, which includes sedimentary rocks containing dated zircons, could help establish a Global Boundary Stratotype Section and Point (GSSP) for the Cryogenian period, marking significant developments in complex life and multicellular organisms.
