Frank et al. (1986a) inferred a terrestrial mass influx of 10⁸ g icy comets of ∼10¹⁵g a⁻¹. About 20‐40% of the mass of known comets is comprised of chondritic rocky matter, thus the associated influx of chondritic matter is inferred to be at least 2 · 10¹⁴ g a⁻¹. Iridium‐accumulation evidence indicates a total influx of chondritic extraterrestrial matter having masses in the range 10⁻¹⁴ to 10¹⁷ g of 7.8 · 10¹⁰ g a⁻¹, 2500 times smaller; >99% of this infalling matter is in masses <10⁻² g or >10¹¹ g. For bodies in the 10⁷‐10⁹ g range the inferred flux is 10⁸ g a⁻¹, a factor of 2 · 10⁶ lower than that inferred for the Frank et al. comets. Because there must be devolatilized objects in the same population, the actual discrepancy is larger, probably ∼3 · 10⁹.
