陨石(meteorite)也称陨星,是地球以外脱离原有运行轨道的宇宙流星或尘碎块飞快散落到地球或其它行星表面的未燃尽的石质、铁质或是石铁混合的物质,陨石在降落地面前与大气层发生摩擦,在高速高温的环境下,表面会形成一层薄薄的熔壳。在降落的陨石中,铁陨石只占陨石降落的一小部分,但在收集的陨石中,铁陨石数量占所有陨石量的将近一半。这是由于由铁镍金属组成的铁陨石,保存时间可以很长,不像石陨石容易风化。铁陨石主要由铁纹石和镍纹石两种矿物组成,其次含有少量的石墨、陨磷铁镍矿、陨硫铬矿、陨碳铁、铬铁矿和陨硫铁等。在化学成分上除Ni和Fe外,还含有Co、S、P、Cu、Cr、Ga、Ge和Ir等元素。有少数铁陨石还含有硅酸盐包体。 此块铁陨石呈不规则体,体积小密度高,重量2708克,有着磁性,表面的熔壳、气印也是十分的明显,完全符合铁陨石的基本特性,陨石这几年还是有着不错的市场关注度,所谓的一石千金现今已不再是远古的神话,而是陨石收藏潜能的蓬勃爆发,前景非常可观,加上持有名家老师的鉴定证明,值得收藏。 近几年,国内逐渐兴起了一股陨石收藏热潮。几年间,不但陨石的价钱飙升,国内陨石收藏也日渐成形。五六年前,陨石所带来的经济价值还不为人所熟知。从无人知晓、无人关怀、无人过问、无人重视,到陨石收藏体系已经基本形成,人们关注的不仅仅是是陨石的本身价值,还有铁陨石的科研价值,对于研究宇宙的无穷与神秘的意义。 在古老的历史长河中,人们将陨石视为圣物。比如,古罗马人把陨石当做神的使者,他们在陨石坠落的地方盖起钟楼来供奉。匈牙利人则把陨石抬进教堂,用链子把它锁起来,以防这个神的礼物飞回天上。在中国,《左氏传》云:陨石,星也。种种迹象表明,在古代,陨石是人们眼中极为珍贵的圣物。其实不止古代,直至现今,陨石仍被认为具有强大的神秘宇宙能量,是宇宙中第四度空间的天使,具有强大的辟邪能力,并能转运开运,辟邪、镇宅等。泰国、东南亚等国和西藏的高僧把陨石称为天铁,常常将其做成护身符和金刚杵等法器进行修炼。 近年来,随着陨石知识的日益普及,被称为天外来客的陨石逐渐进入人们视线,不少收藏家对它更是爱不释手,国内的陨石收藏热潮也随之悄然兴起。如今,铁陨石更是形成疯涨局势,成交价格屡屡被刷新,真正的一石千金,市场前景一片明朗。一般而言,陨石可分为石铁陨石、石陨石和铁陨石三种,其中铁陨石因其独特的历史价值和科研价值备受收藏新贵们的追逐。铁陨石在所有陨石类别中所占的比例为百分之一,也就是说天上落下来一百块陨石中,才有一块为铁陨石,可见其极为宝贵,价值弥足珍贵。 Meteorite,alsoknownasmeteorite,istheunburnedstone,ironormixedmaterialofstoneandironscatteredonthesurfaceoftheearthorotherplanetsbycosmicmeteorsordustfragmentsoutoftheiroriginalorbitoutsidetheearth。Themeteoriterubswiththeatmospherebeforelandingontheground。Intheenvironmentofhighspeedandhightemperature,athinmoltenshellwillbeformedonthesurface。Amongthefallingmeteorites,ironmeteoritesaccountforonlyasmallpartofthefallingmeteorites,butamongthecollectedmeteorites,ironmeteoritesaccountfornearlyhalfofallmeteorites。Thisisbecausetheironmeteoritecomposedofironandnickelmetalcanbepreservedforalongtime。Unlikethemeteorite,itiseasytoweathering。Ironmeteoritesaremainlycomposedoftwominerals,namely,ferrititeandnickeloite,followedbyasmallamountofgraphite,meteoriteferrophosphatenickelore,meteoritechromite,meteoritecarboniron,chromiteandmeteoritepyrite。Intermsofchemicalcomposition,inadditiontoNiandFe,italsocontainselementssuchasCO,s,P,Cu,Cr,GA,GEandIR。Afewironmeteoritesalsocontainsilicateinclusions。 hisironmeteoriteisirregular,smallinsize,highindensity,andweighs648g。Ithasstrongmagnetism。Themoltenshellandgassealonthesurfacearealsoveryobvious,whichisfullyinlinewiththebasiccharacteristicsofironmeteorite。Themeteoritestillhasagoodmarketattentioninrecentyears。Thesocalledonestoneandathousandgoldisnolongeranancientmyth,Itisthevigorousexplosionofmeteoritecollectionpotential,whichhasaverypromisingprospect。Inaddition,itisworthyofcollectionwiththeidentificationoffamousteachers。 Inrecentyears,anupsurgeofmeteoritecollectionhasgraduallysprungupinChina。Inrecentyears,notonlythepriceofmeteoriteshassoared,butalsothedomesticmeteoritecollectionhastakenshapedaybyday。Fiveorsixyearsago,theeconomicvalueofmeteoriteswasnotwellknown。Fromnooneknows,noonecares,noonecares,noonepaysattention,tothemeteoritecollectionsystemhasbeenbasicallyformed。Peoplepayattentionnotonlytothevalueofmeteoriteitself,butalsotothescientificresearchvalueofironmeteorite,whichisofinfiniteandmysterioussignificancetothestudyoftheuniverse。 Inthelongriverofancienthistory,peopleregardmeteoritesassacredobjects。Forexample,theancientRomansregardedmeteoritesasmessengersofGod。Theybuiltabelltowerwheremeteoritesfell。HungarianscarriedthemeteoriteintothechurchandlockeditwithchainstopreventthegiftofGodfromflyingbacktoheaven。InChina,Zuosbiographysays:meteorites,stars。Varioussignsshowthatinancienttimes,meteoriteswereextremelyprecioussacredobjectsinpeopleseyes。Infact,notonlyinancienttimes,buteventoday,meteoritesarestillconsideredtohavestrongmysteriouscosmicenergy。Theyaretheangelsinthefourthdimensionoftheuniverse。Theyhavestrongabilitytowardoffevilspirits,andcantransport,wardoffevilspirits,townhouses,etc。EminentmonksinThailand,SoutheastAsiaandTibetcallmeteoritesheavenlyiron,andoftenmakethemintoamuletsandVajrapestlesforcultivation。 Inrecentyears,withtheincreasingpopularityofmeteoriteknowledge,meteoritesknownasvisitorsfromoutsidetheworldhavegraduallycomeintopeoplessight,andmanycollectorslovethemmore。TheupsurgeofmeteoritecollectioninChinahasalsoquietlysprungup。Nowadays,theironmeteoritehasformedasoaringsituation,thetransactionpricehasbeenrefreshedrepeatedly,therealonestoneisgolden,andthemarketprospectisbright。Generallyspeaking,meteoritescanbepidedintostoneironmeteorites,stonemeteoritesandironmeteorites。Amongthem,ironmeteoritesarepursuedbycollectionupstartsbecauseoftheiruniquehistoricalvalueandscientificresearchvalue。Ironmeteoritesaccountfor1ofallmeteorites,thatis,onlyoneofthe100meteoritesfallingfromtheskyisironmeteorite。Itcanbeseenthatitisextremelypreciousandvaluable。
