摘　　要：介绍一种新型菊花石,白底黑花,轮廓分明,立体感强,有较高的观赏价值。这种菊花石产于新疆阿尔泰地区,由汽水热液作用形成。"花瓣"部分为放射状锂闪石,基底岩石为云母片岩。这种菊花石致密坚硬,不易风化,便于收藏。The new type of chrysanthemum with white ground and black pattern is of great value on ornament for its well distributed and more solid leaves. It occurs in the Ahai of Xinjiang and is formed by steam-water hydrothermal process. The leaves are holmoustite and the ground is mainly mica schist. This type of chrysanthemum stone is more rigid and compact, and is convenience for collection.
