Calcium and copper isotope signatures in hydrothermal sediments as proxies for hydrothermal activity on mid-ocean ridges

Research data for the paper "Calcium and copper isotope signatures in hydrothermal sediments as proxies for hydrothermal activity on mid-ocean ridges" submitted to Geochimica et Cosmochimica Acta. This dataset contains (1) a Word file containing the Ca and Cu isotope compositions of hydrothermal sediments collected from the Carlsberg Ridge, Northwest Indian Ocean; and (2) an Excel file with chemical compositions of the hydrothermal sediments.

本数据集为投稿至《Geochimica et Cosmochimica Acta》（地球化学与宇宙化学学报）的论文《热液沉积物（hydrothermal sediments）中钙与铜同位素指纹（isotope signatures）作为洋中脊（mid-ocean ridges）热液活动替代指标》的配套研究数据。数据集包含两项内容：(1) 一份Word文档，收录了采集自西北印度洋卡尔斯伯格洋脊（Carlsberg Ridge）的热液沉积物的钙、铜同位素组成数据；(2) 一份Excel表格，包含该热液沉积物的化学组成信息。
