La.ge-sca.e gra.itic plutons a.e exposed in the Ergun block in the northern pa.t of the Da.Hingga. Ra.ge, but their empla.ement a.e a.d petrogenesis rema.n un-known. Of these plutons, the Ta.e pluton is composed ma.nly of porphyritic syenogra.ite a.d monzogra.ite, with minor hornblende a.ka.i feldspa. gra.ite a.d ga.bro, which ha.e a.finities to post-orogenic gra.itoids. La.er-a.la.ion Induc-tively Coupled Pla.ma.Ma.s-spectroscope (La.ICP-MS) a.a.ysis shows tha. the ma.or rock types of the Ta.e pluton formed a. 494-480 Ma.a.o, indica.ing its empla.ement in the Ea.ly Pa.eozoic. It is concluded, therefore, tha. the colli-sion between the Ergun a.d the Xing’a. blocks ended in Ea.ly Pa.eozoic. Considering the geochronologica. da.a.of the plutons in the a.ja.ent a.ea., the Ea.ly Pa.eozoic evolu-tiona.y history of the Ergun block is simila. to the centra. Mongolia.a.d the Tuvino blocks in Mongolia. a.d the Ergun block should be a.pa.t of the a.cretiona.y continenta. ma.-gin in the southern Siberia. Cra.on.

Slow eva.ora.ion method wa. used to grow pure a.d KCl (10 mol%) doped Ka. single crysta.. The solubility a.d meta.ta.le zone width of a.ueous solutions of pure a.d KCl (10 mol%) doped Ka. crysta. were eva.ua.ed to a.a.yze the crysta.liza.ion process. Mea.uring the induction period τ, the critica. nuclea.ion pa.a.eters like interfa.ia. energy (σ), energy of forma.ion of the critica. nucleus (ΔG*) were determined using the cla.sica. theory of nuclea.ion. The structura. properties a.d optica. consta.ts of the grown crysta.s ha.e been put to test a.d observed tha. the a.dition of KCl results in a. enha.cement of properties of the crysta..
