Chrysanthemum stones, distributed in the Daxi River valley in Yonghe in Yonghe Town, Liuyang City, belong to the category of marine deposits. A Chrysanthemum stone consists of stamen and petals. Flint, a kind of silicoide separated from marl or siliceous nodule, forms the stamen. Calcite or zolestin takes the coral framework, forming petals. These petals radiate from the center. Reserves totaling 160,000 tons have been verified of chrysanthemum stones.
