中文摘要
1989年10月,主要研究人员开始研究 德瓦尔斯将离散的岩浆和构造单元 东太平洋海隆 他们使用了“岩石取芯”取样 技术,以及疏浚和新的预制岩心 在198个地点收集样本。 底部照片和 还获得了录像。 其结果是一个前所未有的数据集 其中包括非常精确定位的样本,包括沿沿着和沿 东太平洋海隆,超过近50公里的山脊。
英文摘要
In October 1989, the principal investigators began a study of the extent to which Devals bound discrete magmatic and tectonic units of the East Pacific Rise. They used a 'rock coring' sampling technique, as well as dredging and a new precussion core rock sampler to collect samples at 198 sites. Bottom photographs and videos were also obtained. The result is an unprecedented data set that includes very precisely located samples, both along and across the East Pacific Rise, over nearly fifty kilometers of ridge.
