環(huán)境中，以韌脆性變形為主，礦化以脈狀為主。低中角閃巖相，以韌性變形為主，有葉理狀、條紋狀礦化和極少量的微脈狀礦化。在綠片巖相和角閃巖相邊界處，礦化主要以脈、不規(guī)則脈、剪切葉理礦化為主。剪切變形特征受圍巖的性質(zhì)、應變速率及圍巖壓力的影響。圍巖的性質(zhì)不同，礦化結(jié)構(gòu)也不同。在能干層中，以發(fā)生擴容帶(易發(fā)生脆性)，主要以脈狀礦石為特征。當流體壓力大于圍巖時，巖石易出現(xiàn)脆性變形，而出現(xiàn)了脈狀礦石。這種脈狀礦石是由于流體壓力大而形成的裂隙不斷重復的結(jié)果。圍巖蝕變一般發(fā)生與斷裂帶附近幾十公分的范圍內(nèi)。原文：AdvancesinductileshearzonesandtheirgoldmineralizationsignificanceABSTRACTDuctileshearzonesplayanimportantroleingoldmineralizationsincetheyarefavorablesitesforgeneratingandtransferringofgold—bearinghydrothermalfluids．Thispapersummarizestherelationshipsbetweenductileshearzonesandgoldmineralization．Differentmovementstagesofshearzonesandgolden—richmentmechanism，alterationcharacteristicsandthemetallogenicmodelarealsodiscussedinthispaper．Keywords：gold—bearingshearzone；golddeposit；researchadvance1.shearzoneandtherelationshipbetweengoldmineralizationManyveinsofgolddepositsintheworld,andmorerelevantwiththelargelinearfaultzone,whichismainlyfaultorshearzonewithstrongschistosity,istheincreaseinchannelsandhydrothermalgoldenrichmentsites.Asanextensionofductileshearzonesoftenhaveafardeeper,long-termactivities,features,andmagmaticactivityandhydrothermalactivityisrelativelystrongintheareaof??mineralizationisveryfavorable.Scholarsattachgreatimportancetorelationsbetweenshearzonesandmineralizationstudy,whichisparticularlyin-depthstudyofgold(Col-vine,1989;Foster,1989;WuMeide,1989;HeShaoxun,1996).Notonlyshear-richSiO:strongrockcrushingandmylonitic,whiletheformationofporousandquartz-likecrystalsugarhole,butalsosoastogeneratenewminerals,mineralre-adjustandmakethemetaldispersionelementactivation,migration,mineralizationinfavorablelocations.Shearzonestructureisnotonlytheore-controllingfactors,butalsoimportantmetallogenicmechanism(WuMeide,etc.,1989).Gold-bearingshearzonetypegolddepositsareaclassofboththenumberofvein-typedeposits,includingsomedisseminatedtypedeposit,theshearmechanismandcontrollingfactorsforthemineralizationofthegolddeposit.Ramsayin1980,formallyandsystematicallyelaboratedlaterductileshearzone,manyscholarsathomeandabroadhavebeentheformationmechanismoftheductileshearzonewerecomplementarystudies(egListeretal,1984).Ramsay(1980)proposedcanbedividedintobrittleshearzone,aductileandbrittle-ductileshearzonethreecategories.Asearlyas1977,theBritishOuterHebrideSibsonstudythecharacteristicsofthrustfault,youmade??alargedoublefaultrheologymodel.Onthestructurallevelislocatedintheuppercrust,generatedbythefrictionmechanismofrandomfabricfaultrocksformed.Thefollowingisadeepstructurallevelshearzone,generatedbytheplasticmechanismwithlinemanagementandthecompositionoffoliationfabriccomposedofmylonite.Andthetransitionphasebetweenthetwo,thetemperatureis250~350℃,themainductiledeformation,equivalenttogreenschistfacies.After,Mattauer(1980),Scholz(1988)andZhuZhicheng(1988)onthebasisofthemodelwassupplementedandimproved.Ductileshearzoneduringdeformation,resultinginalargenumberofmacroandmicrostructure,providesspaceforthegoldsolutionandthechannel.Sincestrainhardeningandtheriseinthecrustasmountainbuildingandotherreasonstobringinthesuperpositionofthebrittleductile,brittle-ductiledeformation,suchassuperimposedontheRiedelshearbeltfaultsystem.Thesesystemsareverygoodhoststructures.ManyveingoldtoproduceinsuchFracture.Shearzonewhiledrivingintothemigrationandconcentrationofminerals(Colvine,1989;Foster,1989;YueShietal,1990).Fluidpresentindifferenttypesandnatureoftheshearzone.ComponentstoCOz-H.Obased.Intheductileshearzone,metamorphicfluids,inparticular,isthedrivingforcesofteningplaystheroleofmetamorphicfluids,oftenformedinhigh-temperaturehydrothermalalteration.Inthebrittleshearzone,thesystemisanopensystem,water-rockinteractionisveryobvious,strongmaterialexchange,oftenformedinlowtemperaturehydrothermalalteration.Theresultofthefluid,oftenwiththeformationofmetasomaticalteration,waterbrecciazone,hydrothermalzone,micro-fracturezoneandthemineralizedzone.Fluidshearzonestendtocarryalargenumberofformingmaterials,andtobecomeore-formingfluids.Sourceofore-formingfluidhasacomplex,are:theintrusionofmagmacrystallizationreleasedduringdecompositionorfluid,metamorphicdehydrationprocessproducesvolatilefluidremoval,compactionortectoniccompressionresultingcontractionofthefluid,airorwaterunderrainfallProducedbyinfiltrationoffluidcirculation,theroleofthemantleresultingexhaustmetasomatismproducedfluidandthefluid.2.gold-bearingshearzoneevolutionBonnemaisonetal(1990)instudyingFrenchHercyniangold-bearingshearzonesofthebasementmadethethreeevolutionarystages.Theirworkshowsthatdepositsofeconomicimportancehaveoccurredintheshearzonecomplexmulti-stageevolutionaryrelated.Eachstagehasitsowncharacteristicsanduniquemineralsfromtherichgold.
