Tochilinite, an ordered mixed-layer mineral containing Mg, Al, Fe, Ni, S, and O, has been identified in an interplanetary dust particle (IDP). This mineral is found in only one other class of meteoritic materials, type CM carbonaceous chondrites. The presence of tochilinite in an IDP provides a direct petrogenetic link between a member of the layer-silicate subset of IDPs and a specific class of meteorites and thus establishes that some IDPs collected in the stratosphere have an asteroidal origin. The scarcity of this IDP type suggests that materials with CM mineralogy are not abundant among the dust-producing asteroids.
在一颗行星际尘埃粒子（IDP）中发现了层状硅酸盐亚类的 IDP 与特定类型的陨石之间存在直接的成因联系，从而表明在平流层中收集到的一些 IDP 具有小行星起源。这种 IDP 类型的稀缺性表明，产生尘埃的小行星中富含 CM 矿物的物质并不丰富。
