Major and trace element analyses of hawaiites/basanites and associated mineral phases from the Cima Volcanic Field, California and adjacent deposit at Dish Hill

This dataset presents whole-rock major- and trace-element analyses of hawaiites and basanites from the Cima Volcanic Field, California and adjacent deposit at Dish Hill, using inductively coupled plasma mass spectrometry. This dataset also includes electron microprobe analyses of associated mineral phases including olivine, clinopyroxene, plagioclase, and Fe-Ti oxides (ilmenite and titanomagnetite). Whole-rock and mineral compositions are used to place constraints on temperature, melt H2O content, and fO2 using a variety of crystal-melt thermometers, hygrometers, and oxybarometers.本数据集收录了美国加利福尼亚州锡马火山场（Cima Volcanic Field）及毗邻迪什山（Dish Hill）矿床产出的夏威夷岩（hawaiite）与碧玄岩（basanite）的全岩主量元素、微量元素分析数据，分析方法采用电感耦合等离子体质谱法（inductively coupled plasma mass spectrometry）。本数据集同时包含橄榄石、单斜辉石、斜长石以及铁钛氧化物（钛铁矿与钛磁铁矿）等伴生矿物相的电子探针分析数据。研究人员基于全岩与矿物组成，结合多款晶熔温度计、熔体水含量计与氧逸度计，对岩浆温度、熔体水含量及氧逸度（fO₂）进行了约束限定。
