Abstract

A DETAILED investigation of Lower Triassic mud and core samples from north-west German oil wells which I have carried out has revealed the presence of cosmic spherules in considerable numbers. Although magnetic and vitreous spherules originate also from various industrial processes, there seems to be little doubt that the spherules referred to represent genuine cosmic matter, as their main components are magnetite and an iron–magnesium silicate (olivine or bronzite). Thus they have the same composition as the Sikhote-Alin spherules extracted from the soil after the fall of that meteorite. Spherules from deep-sea sediments show the same composition.
