我国含铀磷块岩主要产在下寒武统,其中扬子地台西缘含铀磷块岩也不例外,从陕西汉中-滇中沿扬子地台西缘[1],北起汉中宁强-四川峨嵋-雷波-会东-云南滇中晋宁长达1000km,到南缘贵州境内磷块岩广泛分布,含铀磷块岩系主要赋存于下寒武统底部与上震旦统顶部,与含铀磷块岩型铀矿化关 The uranium-bearing phosphatic blocks in our country are mainly produced in the Lower Cambrian. The uranium-bearing phosphatic blocks in the western margin of the Yangtze platform are no exception. From Hanzhong to central Yunnan along the western margin of the Yangtze Platform [1] Sichuan Emei - Leibo - Huidong - Yunnan Yunnan Jinning up to 1000km, to the southern margin of Guizhou phosphorous widely distributed, mainly containing uranium phosphate rock strata at the bottom of the Lower Cambrian and the top of the upper Sinian , With uranium phosphate rock type uranium mineralization
