Nws ntseeg tau tias tag nrho cov tshuaj muaj nyob rau hauv keeb kwm muaj nyob rau hauv huab protoplanetary. Los ntawm nws tsim: ib tug hlau core nyob rau hauv nruab nrab ntawm lub ntiaj teb no thiab ntau yam minerals nyob ib ncig ntawm nws. Thiab txawm hais tias qhov no tsuas yog ib qho qauv, ib qho kev xav - nws yog qhov tseem ceeb.

Ntau cov hlau los ntawm sab hauv los ntawm plumes (convection currents nyob rau hauv lub mantle) thiab volcanism xaus nyob rau hauv nto ore deposits los yog deposits.

Thiab lo lus dab tsi: deposit! Los yog: haiv neeg kub. Cov. rau qee qhov laj thawj, nyob rau hauv Lavxias teb sab lus, cov txheej txheem ntawm kev tsim ntawm ib co hlau tshwm sim los ntawm lawv yug nyob rau hauv lub ntiaj teb no, thiab tsis yog los ntawm kev hloov thiab poob los ntawm qhov chaw.

Tej zaum qhov no yog li ntawd, tshwj xeeb tshaj yog thaum koj saib cov piv txwv hauv qab no:

Kub nyob rau hauv ib tug quartz leeg. Nws pom tau hais tias quartz muaju loj hlob nyob rau hauv no conglomerate. Tab sis raws li nyob rau hauv ib lub qhaub cij, muaj kub nruab nrab ntawm lawv. Thiab kuj nyob rau hauv ib tug peculiar daim ntawv, tsis zoo li ib tug khov yaj.

Kuv nqis peev tsab xov xwmnrog ib tug version hais txog lub hollow qauv ntawm ntiaj chaw thiab hnub qub. Qhov no kuj yog ib qho kev xav, txawm hais tias nws overturns ntau ntawm peb lub tswv yim txog lub ntiaj teb no.

Ntawm no koj tuaj yeem pom tias cov hlab ntsha ntawm kub tau loj hlob zoo li cov qauv dej khov rau ntawm iav - zoo li ib ceg ntawm cov nroj tsuag, fern.

Kuv tam sim ntawd nco qab cov lus tim khawv ntawm cov miners thiab cov kev ntseeg ntawm geology hais tias xws li "txog" thiab "nplooj" nyob rau hauv cov khaubncaws sab nraud povtseg ntawm thee yog supposedly 100% pov thawj hais tias thee yog los ntawm cov roj ntsha. Tias cov no yog coked deposits ntawm ancient flora.

Kuv tau sau ntau zaus tias muaj ntau npaum li cov sulfur nyob rau hauv coals li tsis muaj nyob rau hauv tej ntoo lossis nyom. Sulfur concentration tsis piv rau kev ua neej lom neeg. Bituminous thiab xim av thee yog cov hauv paus chiv keeb abiogenic. Cov no yog petrified roj outflows tom qab kev puas tsuaj. Thiab cov ceg ntawm supposedly ferns - qhov no yog li cas graphite thiab carbon loj hlob nyob rau hauv tej yam kev mob.

Cia peb rov qab mus rau kub. Xws li daim duab nrog kev loj hlob ntawm cov hlab ntsha kub, ua raws li cov ceg ntawm cov nroj tsuag, yog kev loj hlob ntawm cov muaju thiab tuaj yeem tshwm sim los ntawm yaj lossis los ntawm kev daws. Kuv yog ib tug txhawb nqa ntawm qhov thib ob version. Cov lus piav qhia tib yam yog nrog kev tsim cov muaju ntawm silicon dioxide hauv granite - los ntawm cov tshuaj overheated (kua txiv) nyob rau hauv siab lossis thaum qee qhov kev hloov pauv.

Cov qauv frosty ntawm lub qhov rais kuj tsis loj hlob zoo li ntawd - koj xav tau qee qhov kub ntawm lub khob thiab muaj cov dej noo hauv huab cua. Kuv xav tias nws zoo ib yam nrog kub. Nyob rau hauv lub broth, nplej ntawm quartz thiab ib tug "ceg" ntawm kub pib loj hlob thaum lub cev yam ntxwv ntawm lub broth hloov.

Geologically, kub yog feem ntau pom nyob rau hauv hydrothermal quartz leeg. Cov. quartz tuaj yeem hais tias tau loj hlob los ntawm kev daws teeb meem ntawm hydrothermal vents. Tej zaum, kub yog tib yam.

Placer kub nyob rau hauv cov xuab zeb thiab av twb yog ib yam khoom ntawm kev puas tsuaj ntawm tej conglomerates, thaum kwj ntawm dej yaig puas thiab ntxuav tawm no pob zeb.

Kub tuaj yeem crystallize, loj hlob tawm ntawm kev daws thiab mus rau hauv cov ntaub ntawv hauv qab no:

Nyob rau sab laug, nws muaj cov qauv siv nrog quartz siv lead ua. Ntawm sab xis yog cov ntaub ntawv crystalline tus kheej.

Crystalline kub zus los ntawm kev thauj mus los. Cov. kev loj hlob ntawm kub tuaj yeem rov tsim dua hauv chav kuaj.

Lwm cov hlau tseem ceeb ntawm pab pawg platinum kuj tseem loj hlob tuaj:

Crystalline Platinum

Palladium siv lead ua

Qhov xaus yog qhov no: thaum lub sij hawm geotectonic kev puas tsuaj rau lub ntiaj teb (lub ntiaj teb no extinction ntawm flora thiab fauna raws li geochronology), cov txheej txheem coj mus rau qhov tshwm sim ntawm tshiab deposits ntawm ntau yam hlau thiab minerals. Kuv xav tias qhov no tsis yog txheej txheem maj mam, tab sis cuam tshuam nrog kev puas tsuaj sai sai hauv lithosphere. Tab sis dab tsi ua rau xws li destabilization ntawm subsoil?
