(Table 2) Major-element compositions of selected primary minerals: plagioclase, amphibole, mica, Ti-magnesiochromite, and Ti-magnetite at DSDP Site 89-585@en

Empty cells indicates concentration below detection limit. All iron in feldspar calculated as Fe3+, as Fe2+ in kaersutite and biotite; Fe3+ in oxides calculated assuming cation sum of 24.00.

空单元格代表该组分浓度低于检测限。长石中的铁全部以三价铁（Fe³+）形式计算，钾角闪石（kaersutite）与黑云母（biotite）中的铁则以二价铁（Fe²+）形式计算；氧化物中的三价铁则按照阳离子总和为24.00的假设进行计算。
