300 tons/day = 109,500,000,000,000 tons in 1 billion years.
Average density of the Earth's crust is about 3.2 g/cm3 so lets use that. We get a volume of 31.042 cubic kilometers. Using the current surface area of the Earth, that would make a layer about 2.5 inches thick...after 1 billion years.

created by the collision of 2 tectonic plates?
Continent vs. continent collision raised the Appalachian-Ouachita chain to lofty, Himalayan-scale ranges.
No. The Solar System passes through the Galactic equator once every 30 million years or so. www.astro.ncu.edu.tw...
by the way is there any truth to the idea that the solar system and indeed the local group of stars that we are part of actually move through the galactic ecliptic every 50.000 or so year's and does that not indicate the possability that this level of debris may be more variable than we currently estimate as varient orbist cross track's.
