From Nature

Because the Earth pulls siderophile, or iron-loving, elements such as iridium or gold inward to its core, the planet's crust contains relatively low concentrations of these molecules.

From Scientific American

Meanwhile, space debris contains more siderophile elements than the Earth's crust, and space rocks such as asteroidstypically contain more of these elements than do comets, which are known as the "dirty snowballs" of the solar system.

From Scientific American

However, it has not yet been possible to measure in a lab the solubility of all the highly siderophile elements over the full range of temperatures and pressures of the Earth's mantle, so for now this proposed explanation for the abundance of gold also remains no more than a hypothesis.
