This rock zone, with a NE striking, the whole length of 1 400 km and the width of 100~150 km, is characterized by not onlyalkaline rocks (analcite biotite olivine melilitites, leucititic alnoites, nephelite syenites, aegirite augite syenites, melanite syenites, riebeckite syenite and aegirite bearing quartz syenites) and alkaline granite (riebeckite granite, and aegitite augite riebeckite granite), but also a lot of syenites, monzonites and alkaline feldspar granites or miarolitic K feldspar granites.
该岩带全长约1400km,宽100~150km,不仅发育有狭义的碱性岩(方沸黑云橄榄黄长岩、白榴黄长煌斑岩、霞石正长岩、霓辉石正长岩、黑榴石正长岩和含霓石石英正长岩)和碱性花岗岩(钠闪石花岗岩、霓辉石钠闪石花岗岩),还发育有大量的正长岩类二长岩类碱长花岗岩或晶洞钾长花岗岩。

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。

It has been shown in the Al(Na+K+Ca/2) diagram that the Jinla granitoids are all plotted within the area of "S" type of granites, but the samples from Laochang amphibole admellite, Menglinshan biotite admellite and Nanla K-feldspar graniteporphyry are scattered gradually far away from the boundary between "I" and "S" types of granites, implying that the components from the upper mantle gradually decreasing from the Laochang amphibole admellite to the Menglinshan biotite admellite and then to the Nanla K-feldspar granite porphyry.
3上述三类花岗岩样品皆位于S型花岗岩区,但从老厂似斑状角闪二长花岗岩,勐林山似斑状黑云二长花岗岩,到南腊碱长花岗斑岩,样品分布逐渐远离"I"型花岗岩和"S"型花岗岩的分界线,这表明自老厂似斑状角闪二长花岗岩至勐林山似斑状黑云二长花岗岩,到南腊碱长花岗斑岩幔源组分逐渐减少。
