如果将地球自诞生至今的历史化为一天,则直到年夜前一分多钟,我们人类才出现。那么;我们是如何得知以前的历史、了解地球的诞生呢?地球不会说话,无法亲口告诉我们它的年龄,所以我们必须借助一种能够“铭刻时间”的奇特矿物——锆石。测量地球的年龄,为什么要靠这连名字都那么拗口的石头呢?难道不能在地球上那些没有人类或其他生物干扰的地方随机提取一些岩石矿物的样本来测量吗?这当然是不行的!因为通过火山活动、板块运动等方式回收老旧的岩石,并将新生的岩石带到地表,地球不断地更新着自己的外貌,同时也掩盖了自己的真实年龄。所 If the history of the Earth from its birth to this day is one day, human beings will not emerge until more than a minute before the night. So how do we know the history of the past and understand the birth of the earth? The Earth can not speak and can not tell us its age by itself, so we must resort to a peculiar mineral that can “etch time” - zircon . Is it not possible to measure the age of the earth by the stone whose name is so hard to pronounce? Is it not possible to take samples of rock minerals randomly from places on the earth that are free of human or other biological disturbances? Through volcanic activity, plate movement and other means of recycling old rocks, and new rock brought to the surface, the Earth constantly updated its own appearance, but also cover up their true age.
