Dataset for "Weathering and paleosol formation in the 1.1Ga Keweenawan Rift"

At a road cut section at Good Harbor Bay, Cook County, Minnesota, and along Cut Face Creek on the northeast part of the road section, 89 samples were taken with a hammer after removing about 10 centimeters of rock from the outcrop surface. Analysis was done with a PerkinElmer Optima 3300RL ICP-AES System and a PerkinElmer 5000 ICP-MS system for trace elements. A James Smith Model F Point Count machine for point count data and a Hitachi S3000 SEM for SEM and EDX images were also used. Dried samples were used for Munsell Soil colors. These analyses were done at Royal Holloway, University of London.

在明尼苏达州库克县（Cook County）古德港湾（Good Harbor Bay）的公路路堑段，以及该路段东北部的切面溪（Cut Face Creek）沿岸，研究人员先刮除露头表面约10厘米厚的岩层，随后使用锤子采集了89件岩石样品。本次研究采用珀金埃尔默（PerkinElmer）Optima 3300RL电感耦合等离子体原子发射光谱（ICP-AES）系统与珀金埃尔默5000电感耦合等离子体质谱（ICP-MS）系统，对样品中的痕量元素开展检测；此外还使用James Smith F型点计数仪获取点计数数据，并借助日立（Hitachi）S3000扫描电子显微镜（SEM）采集扫描电镜与能量色散X射线（EDX）图像。门塞尔土壤颜色（Munsell Soil Color）测定采用干燥后的样品完成。所有分析工作均在伦敦大学皇家霍洛威学院（Royal Holloway, University of London）进行。
