Cambrian is the main metallogenic era of phosphate rock bearing both in Xinjiang and Kazakhstan. In Xinjiang, the Cambrian phosphate rock ore bed is thin, ore quality is poor, reserve volume is very low; but in small Kalataoshan, Kazakhstan, the Cambrian phosphate rock ore bed is thick, ore quality is good, reserve volume is huge. On strategically "going out", the rich abundant phosphate rock resource in small Kalataoshan of neighboring country have an important significance that to make up the serious shortage of the Xinjiang phosphate rock resource.
