Geochemistry of plagioclase from the Mid-Atlantic Ridge

We have studied the chemical zoning of plagioclase phenocrysts from the slow-spreading Mid-Atlantic Ridge and the intermediate-spreading rate Costa Rica Rift to obtain the time...本研究针对慢速扩张的大西洋中脊（Mid-Atlantic Ridge）与中等扩张速率的哥斯达黎加裂谷（Costa Rica Rift）中的斜长石斑晶（plagioclase phenocrysts）化学环带（chemical zoning）展开分析，旨在获取其形成时间相关信息
