Abstract：Iron cosmic spherules were discovered for the first time in modern coastal sediments of the Rose Garden, which, as a part of the Golden Pebble Beach in Dalian City, is a nation-grade scenic spot where the quantity of cosmic spherules is fairly large. 18 grains were separated from a 2.4 kg sample whose size is less than 0.5mm. The particle sizes of cosmic spherules range from 158 um to 423 um, and most of them possess segregation and mosaic structure on their surfaces. The cosmic spherules can be divided into four types according to their chemical composition, i.e. Fe, Si-Al-Fe, Cr-Fe, and Ti-Fe species. The relationship between minerals in the Ti-Fe cosmic grains, which constitute a species of cosmic spherules collected there, was studied specially in this paper, and the results show that the titanium magnetite was formed around magnetite by quick cooling segregation. Comparative studies of cosmic spherules collected from modern sediments of Dalian in Liaoning and Zedang in Tibet and those from the sediments in deep sea of the Pacific Ocean as well as from the Proterozonic sedimentary rocks in the Ming Tombs of Beijing have shown that their chemical compositions are different from each other, but their particle sizes and surface characteristics are similar to each other.
