摘要
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. Comparative studies of cosmic spherules collected from modern sediments of Dalian in Liaoning Province and Zedang in Tibet and those from the sediments in deep sea of the Pacific Ocean as well as from the Proterozoic 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.
