The study shows that almost all the feldspar in the alkali-granite is perthite, the host-crystal is microcline, the chadcrystal could be either albiter or oligoclase. The Alkali-amphibole is either manganese-magnesia-arfvedsonite or arfvedsonite, and all the alkali-pyroxene is aegirine.

结果表明，该区富碱花岗岩几乎所有的长石均为条纹长石，主晶为微斜长石或高微斜长石，客晶为钠长石或更长石，碱性角闪石为含锰镁质钠铁闪石或钠闪石，碱性辉石均为霓石。

The feldspar in A-type granite is perthite, the dark alkali-minerals in which are arfvedsonite or manganese-bearing magnesia- arfvedsoniteand aegirine.

碱性花岗岩中的长石为条纹长石，暗色矿物为钠铁门石或含锰镁质钠铁门石及霓石。

对于一个侵入岩体的冷却来说，平流冷却与传导冷却一样重要

Sanidinite (some have transformed to perthite) and quartz inclusions with radial cracks are often seen in the garnet of eclogite. The geothermal gradient of ＜10℃/km is recorded in the early stage mineral assemblage of high-pressure metapelitic rocks with relict aragonite. these features imply a possibility that there may be ultra-high-pressure rocks existed in Altun.

根据榴辉岩中石榴石常见透长石和石英包体，并有放射状裂纹的特征，以及高压变泥质岩石早期矿物组合温压条件记录的地温梯度小于10℃/km和残存文石等特征，不排除区内有超高压变质岩石存在的可能性。
