Its geographical coordinates are 100° 11 ′15″-100° 13′00″ E and 60°07′30″26°10′30″ N. Since its discovery in 1999 until November 31st 2013, it has had accumulative proven （111b＋122b＋331 ＋332＋333） gold metal amounts of 258.475 t at an average grade of 2.61 g/t. This deposit contains 88.98 million tons of paragenetic and associated iron ores, with TFe grade varying from 9% to 36%; metal amounts are： gold 27 t; copper 0.6188 million tons; silver 5439 t; lead 1.35 million ton; zinc 0.31 million ton; and sulfur content is 10.09 million ton. Beiya is one of the top ten largest gold deposits discovered in recent years in China.展开更多

Differences between ZLJ0112 and the holotype （subadult specimen） are considered as ontogenetic characteristic changes of L. huenei. Since some of these differences are present in other prosauropod dinosaurs （i.e., forms of the maxillary vascular foramen are irregular; the frontal contribution to the dorsal margin of the orbit is substantial; the frontal contribution to the supratemporal fossa is absent; the supratemporal fenestra is visible in lateral view; the supraoccipital inclined at 75 degrees; the parasphenoid rostrum lies level with the occipital condyle; the retroarticular process is short; the axial postzygapophysis project caudally beyond the end of the centrum） they may be common ontogenetic changes in prosauropod dinosaurs.展开更多

[Result] The yield of Shenyu 10 was up to 66.3.4 kg/ 667 m^2 and there were extremely significant differences between Shenyu 10 and Xuanhuangdan 5 （CK）. Moreover, it had strong stress resistance. As Jingdan 12, Beiju 0913, Ante 8000, Yunrui 89 and Yayu 78 were planted in the region, their earing should not appear in rainy months. The inciderce of stem rot and ear rot of Yayu 891 was high, so Yayu 891 should not be planted in the region. [Conclusion] Shenyu 10 had a high yield, suffered few diseases and had strong stress resistance, so it can be popularized widely in the region.展开更多
