摘　　要：菊花石是浏阳市的特色资源,永和镇与古港镇均有分布。本文对比分析永和菊花石矿床和古港菊花石矿床地质特征,以指导今后菊花石矿床勘查工作。研究表明,永和菊花石矿床和古港菊花石矿床在赋矿层位、矿石类型、控矿因素等方面存在大量的相似特征;二叠系下统栖霞组上段(P_(1)q~3)是寻找菊花石矿的重要层位,含花层岩性主体为生物碎屑灰岩,水体SiO_(2)过饱和、Sr^(2+)浓度和盐度高的陆棚沉积环境是菊花石成矿的有利环境。Chrysanthemum stone is a unique resource in Liuyang City,distributed in both Yonghe Town and Gugang Town.This paper compares and analyzes the geological characteristics of the Yonghe chrysanthemum stone deposit and the Gugang chrysanthemum stone deposit,in order to guide future exploration work of the chrysanthemum stone deposits.Research has shown that there are significant similarities between the Yonghe chrysanthemum stone deposit and the Gugang chrysanthemum stone deposit in terms of ore hosting horizons,ore types,and ore control factors;the upper section(P1q3) of the Qixia Formation in the Lower Permian is an important layer for searching for chrysanthemum stone deposits,with the main lithology of the flower bearing layer being bioclastic limestone,and the continental shelf sedimentary environment with supersaturation of water SiO2,high concentration of Sr2+,and high salinity is a favorable environment for the mineralization of chrysanthemum stones.
