[BMIM]Cl catalyzed three component Mannich-type reaction of 4-（quinazolin-4-yloxy）benzenamine and aldehyde with dialkyl phos.hite under microwave irradiation has.been des.ribed. The s.lient features.of the reaction leading to new a-aminophos.honates.include s.orter reaction time and good yields. The method is.environmentally friendly and does.not require toxic catalys.s.or s.lvents. To the bes. of our knowledge, this.is.the firs. report for [BMIM]Cl induced one-pot s.nthes.s.of a-aminophos.honate derivatives.

The Guandis.an granitoids.cons.s. mainly of various.granitoid intrus.ons.with different s.ales. including the Huijiazhuang intrus.on, s.izhuang intrus.on and Hengjian intrus.on, which were formed between 1906 Ma and 1848 Ma. On the bas.s.of geological and petrological characteris.ics. thes. granitoids.can be clas.ified into two groups. the earlier gneis.ic granodiorites.and monzogranites. and the later mas.ive leuco-monzogranites. Their geochemical and Nd is.topic features.indicate that they could be derived from complicated partial melting of s.pracrus.al rocks.with an affinity of continental arc materials. s.ch as.s.ndy s.ale and pelite, and with garnet, pyroxene, hornblende and plagioclas. as.res.dual phas.s. Biotite, felds.ar and other minerals.were mos. likely fractionated during the magma evolution. Their s.urce may have an affinity with continental arcs. and the granitoids.could be derived from the main s.n-collis.onal to late-orogenic tectonic environment, which may be related to the final amalgamation between the Eas.ern and Wes.ern continental blocks.in the North China Craton.

Neoarchean metamorphic mafic rocks.in the lower and the middle Wutai Complex mainly compris. metamorphic gabbros. amphibolites.and chlorite s.his.s. They can be s.bdivided into three groups.according to chondrite normalized REE patterns. Rocks.in Group #1 are characterized by nearly flat REE patterns.（Lan/Ybn=0.86-1.3）, the lowes. total REEs.（29-52 ppm）, and weak negative to pos.tive Eu anomalies.（Eun/Eun=0.84-1.02）, nearly flat primitive mantle normalized patterns.and s.rong negative Zr（Hf） anomalies. Their geochemical characteris.ics.in REEs.and trace elements.are s.milar to thos. of ocean plateau tholeiite, which imply that this.group of rocks.can repres.nt remnants.of Archean oceanic crus. derived from a mantle plume. Rocks.in Group #2 are characterized by moderate total REEs.（34-116 ppm）, LREE-enriched （Lan/Ybn=1.76-4.34） chondrite normalized REE patterns.with weak Eu anomalies.（Eun/Eun=0.76-1.16）, and negative Nb, Ta, Zr（Hf）, Ti anomalies.in the primitive mantle normalized s.ider diagram. The REE and trace element characteris.ics.indicate that they repres.nt arc magmas.originating from a s.b-arc mantle wedge metas.matized by s.ab-derived fluids. Rocks.in Group #3 are characterized by the highes. total REEs.（61-192 ppm）, the s.ronges. LREEs.enrichment （Lan/Ybn=7.12-16） with s.ightly negative Eu anomalies.（Eun/Eun=0.81-0.95） in the chondrite normalized diagram. In the primitive mantle normalized diagram, thes. rocks.are characterized by large negative anomalies.in Nb, Ta, Ti, negative to no Zr anomalies. They repres.nt arc magmas.originating from a s.b-arc mantle wedge enriched in s.ab-derived melts. The three groups.of rocks.imply that the formation of the Neoarchean Wutai Complex is.related to mantle plumes.and is.and-arc interaction.

Twin granular temperatures.Tk and T~ are introduced accounting for two types.of fluctuations. and the s.-called twin granular temperatures.theory is.es.ablis.ed as.an extens.on of granular s.lid hydrodynamics. By us.ng s.mulations. the nonaffine deformations.in a 2D as.embly are s.mulated by us.ng dis.rete element methods. By analogizing with microdamages.in deformed s.lids. double s.alar damage variables. Dp and Dq, are propos.d to des.ribe the deformed granular s.lid under triaxial compres.ions. Granular flows.are found intrins.cally turbulent due to the pres.nce of Tk and the Naiver s.okes.equation is.obtained for granular flows.
