The pallasites are a class of stony–iron meteorite. They are relatively rare, and can be distinguished by the presence of large olivine crystal inclusions in the ferro-nickel matrix.

橄榄陨铁（橄榄石石铁陨石），是指含有5%左右的 橄榄石 和 锥纹石 、 合纹石 、 镍纹石 和陨硫铁的 石铁陨石。 包含厘米尺度的橄榄石晶体，一种在铁镍 矩阵内的橄榄石成分。 粗金属区域 …

Perhaps the most beautiful of all meteorites, pallasites contain abundant olivine suspended in a nickel-iron matrix. When cut and polished, pallasites reveal translucent crystals, which are …

Pallasites are believed to form between the silicate mantle, or outer shell, and molten metal core of a differentiated asteroid. The primary silicate mineral in pallasites is olivine, distinguishable …

In specimens of one common type of stony iron, known as pallasites (formerly called lithosiderites), the nickel-iron is a coherent mass enclosing separated stony parts.

2019年9月16日 · Our calculations show that ferrovolcanic surface eruptions are more likely on bodies with mantles less than 50 km thick. We show that intrusive ferromagmatism can …

1977年6月1日 · Pallasites are highly differentiated meteorites and provide a unique sample from the deep interiors of solar system parent bodies. They contain evidence of the former …

The main pallasite contains several regions of “massive” olivine clusters up to 11 cm in diameter with thin metal veins only a few millimeters in width. Fo86.4 with molar Fe/Mg = 0.1367, Fe/Mn …

Pallasites are igneous in nature and characterized by crystals of olivine, sometimes peridot (green gem quality clear olivine crystals), embedded in a matrix of Fe-Ni metal. The type specimen, …

Pallasites are mainly composed of subequal proportions of olivine and Fe-Ni metal, with minor amounts of troilite, chromite, Ca-phosphates and schreibersite [14.2]. They are divided into …
