The proportions of major oxides in the Allende carbonaceous chondrite after partial reduction are remarkably similar to those in possible mantle material of the earth. When heated, the Allende meteorite generates a sulfide melt (47 percent iron, 25 percent nickel, and 24 percent sulfur by weight), a ferrobasaltic melt, and olivine with or without pyroxene, over a wide pressure range (5 to 25 kilobars). The silicate melt contains more sodium and less titanium than lunar ferrobasalts. An aggregate of the Allende chondrite rich in calcium and aluminum produces silica-undersaturated, calcium-rich melt and spinel over a wide pressure and temperature range. From these studies, it is suggested that the earth's core contains significant amounts of both nickel and sulfur and that a 3 : 2 mixture of Allende bulk sample and calcium- and aluminum-rich aggregates is closer in major element abundances than either of these components to the average composition of the moon.
阿连德球粒陨石经部分还原后，主要氧化物的比例与地球可能的地幔物质非常相似。阿连德陨石加热时，在很宽的压力范围内（5 至 25 千巴），会产生硫化物熔体（重量百分比为 47%的铁、25%的镍和 24%的硫）、铁镁玄武岩熔体和橄榄石，有或没有辉石。硅酸盐熔体的钠含量比月铁镁玄武岩高，钛含量低。富含钙和铝的阿连德球粒陨石的聚合体在很宽的压力和温度范围内产生硅不饱和、富钙的熔体和尖晶石。从这些研究中可以看出，地核含有大量的镍和硫，而且阿连德总体样本和富含钙和铝的聚合体的 3:2 混合物在主要元素丰度上比这两种成分中的任何一种都更接近月球的平均组成。
