中江花石分类及成因初探

Research on Classification of Zhongjiang Colorful Stones and their Causes of Formation

中江花石，隋唐以来就已著名，并且拥有丰富的花石资源。中江花石资源在清代道光年间，就已经枯竭了。大部分中江花石资源来自凯江上游一西部古地中海域盆周的秦岭、大巴山、龙门山和岷山崩塌下来的4亿年前后的古生代珊瑚化石，经河水搬运至中江圣泉。沿凯江上游的干河子流域及安昌河流域至北川、汶川、茂县等地搜寻中江花石类资源，算是一条捷径。在寒武纪晚期至二叠纪床板珊瑚地层、中奥陶纪至二叠纪四射珊瑚地层、三叠纪至侏罗纪六射珊瑚地层以及寒武纪晚期至第三纪晚期八射珊瑚地层中考寻。花石资源范围将会更加宽广。

Zhongjiang Colorful Stone has been famous since the Sui and Tang Dynasties and Zhongjiang County is rich in colorful stones. Yet by the Daoguang Emperor era, its resource had been exhausted. Many of such kind of stones come from the coral fossil collapsed from the upstream of Kaijiang River and the Mountains of Qinling, Daba, Longmenshan and Minshan, which were from the basin of the west ancient Mediterranean Sea that formed during the Paleozoie Era 400 million years ago. It is a shortcut to go to find the resources of these colorful stones along with the Ganhezi Watershed of the upstream of Kaijiang and Anchanghe Watershed to such places as Beichaun, Wenchaun, Maoxian and so on. The colorful stones are now widely distributed of the coral formation of several ancient eras.
