By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

Hongxing area which is locating in Yichun, southeast Heilongjiang province, is geologically at the binding site of Bulieya-Jiamusi block and Zhangguangcailing orogenic belt. The late Triassic alkali-granite of this area is composing of syenogranite, alkali-feldspar granite and sodium-amphibole and aegirine bearing alkali-granite.

黑龙江省伊春红星地区大地构造上位于布列亚－佳木斯地块和张广才岭造山带结合部位，区内出露晚三叠世碱性花岗岩，其岩石组合为正长花岗岩、碱长花岗岩、含钠闪石、霓石碱性花岗岩。

Because of the existence, quantity and change of chemical composition of pyroxene group minerals, such as jadeite aeginine,vryite and hedenbergite ,largely influence the quality of jadeite.

其中辉石族的矿物如硬玉、霓石、钠铬辉石、钙铁辉石，他们的存在和数量的多少以及化学成分的变化对翡翠质量的影响很大。
