This product union and the optimal near ten years for the domestic feed enterprise, the cultivation factory design's cattle and sheep feed formula, strengthened Va, Vd, Ve, the nicotine acid and the biological element specially and so on, and have included the rumen protein, the rich electrolyte, the trace element, the chelating agent, the seasoner, metabolism regulation medicinal preparation, the nutrition comprehensive and are balanced, may adjust the meat cattle and sheep microcycle, maximum limit enhance the meat cattle's and sheep's protein and do the material amount of radiation, display its heredity potential fully, enhance the cattle and sheep to increase the heavy speed.

本产品结合和优选近十年为国内饲料企业、养殖厂设计的牛羊饲料配方，特别强化了 Va 、 Vd 、 Ve 、烟酸和生物素等，并含有过瘤胃蛋白质、丰富电解质、微量元素、螯合剂、调味剂、代谢调控剂，营养全面且平衡，可调节肉牛羊微循环，最大限度的提高肉牛羊的蛋白质及干物质摄入量，充分发挥其遗传潜力，提高牛羊增重速度。

On the basis of their major and trace element geochemistry of these four Fms., the Beitashan and Yundukala Fms. include tholeiite and calc-alkaline series, characterized by the enrichment of large ion lithophile elements, and the high field strength element contents close to MORB, which suggest that they formed an arc-island setting.

对这4个组火山岩的主要元素、微量元素地球化学特征研究表明，北塔山组和蕴都喀拉组为拉斑和钙碱性系列，并且均具有大离子亲石元素富集，而高场强元素与MORB相当，说明其为岛弧环境。

The basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

玄武岩属岛弧拉斑玄武岩和钙碱性系列，属太平洋型钠质类型，稀土、微量元素显示具岛弧特征，大地构造位置为岛弧中心靠近大洋一侧，与南侧那拉提晚泥盆—早石炭世侵入岩共同组成火山弧，同为古亚洲洋向北俯冲的产物。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。
