湖北省随南大洪山地区之“花山群”自创名以来，是一个集碎屑沉积岩、基性火山岩、酸性火山岩于一体的地质体。解体后的花山群，仅代表碎屑沉积岩组合，该组合进一步划分为洪山寺组和六房咀组，为一套由水下近岸冲积扇至盆地中央的沉积岩系，其下不整合于扬子克拉通中元古代打鼓石群碳酸盐岩褶皱基底之上，其上被南华纪莲沱组不整合超覆，属前陆盆地之构造古地理环境。并与解体出来的基性火山岩和酸性火山岩构成前陆盆地-蛇绿混杂岩带-岩浆弧之大地构造环境模式。

Since “Huashan group” in Dahongshan mountain of south Suizhou of Hubei was named ,it has meant a broad geologic body which contents clastic sedimentary rock ,basic volcanic rock ,acid volcanic rocks .After being decomposed , the “Huashan group” only stand for the clastic sedimentary rock ,which can be divide into Hongshansi formation and Li-ufangzui formation .and it represents the sedimentary body from near-shore subaqueous alluvial fan to the central of basin , which covers on the fold mesoproterozoic carbonatite basement of Dagushi group in Yangtze craton unconformity ,and is o-verlapped by Liantuo formation of Nanhua period , that belongs to the Forelandbasin tectonic-paleogeography .Huashan group together with the basic volcanic rock and acid volcanic rocks that decomposed , they form the Forelandbasin-ophio-lite belt-magmatic arc tectonic-environment mode .
