塔里木地台北緣已发現的磷矿主要为下寒武紀的层狀与結核狀磷块岩,其次有志留、泥盆紀含介壳磷酸鹽化砂岩。目前看來后者价值不大,前者却可成为新疆所需磷肥的主要来源。
The phosphate rock found on the northern margin of the Tarim platform is mainly the laminar and nodular phosphorous rocks of the Lower Cambrian, followed by the Silurian and Devonian sedimentary shell phosphatased sandstones. It seems that the latter is of little value, but the former can become the main source of phosphate fertilizer needed in Xinjiang.
