- n. Plural form of siderophile.
Sorry, no etymologies found.
Their mantles, for example, might be lacking in siderophiles like gold and platinum, which we value for a variety of reasons.
One possibility is that the siderophiles were replenished shortly after core formation by collisions with planetesimals, the smaller building blocks of full-grown planets.
To account for present abundances of gold, platinum and the other siderophiles, researchers said, the impacts would need to deliver about 0.5 percent of Earth's mass to our planet's mantle, 10 times less mass than that to Mars and about 1,200 times less to our moon.
But siderophiles are found in these bodies' upper reaches in perplexing abundances.
