(Table 3) Representative pyroxene and spinel chemistry of basaltic rocks from...

Cation numbers on O = 6 (pyroxenes) and O = 4 (spinels) basis. The oxide values are normalized to total 100%. Fe2O3 of spinel was estimated so as to make cation total 3 on the 4...以氧原子数为6的辉石（pyroxenes）与氧原子数为4的尖晶石（spinels）为基准计算阳离子数。氧化物组分含量归一化至总和为100%。尖晶石的三氧化二铁（Fe₂O₃）含量经估算得到，以确保以4个氧原子为基准时阳离子总数为3……
