Aldan Highlands nyob qhov twg thiab nws yog dab tsi? Nws yog rau cov lus nug no uas koj tuaj yeem tau txais cov lus teb yog tias koj nyeem cov ntaub ntawv uas tau nthuav tawm hauv kab lus no.
thaj chaw
Nyob rau thaj chaw uas niaj hnub koom pheej ntawm Sakha muaj ib lub toj siab hu ua Aldan. Qhov no landform yog ib tug nruab nrab elevation. Yog tias koj saib ntawm daim ntawv qhia, nws nyob rau sab qaum teb sab hnub tuaj ntawm Stanovoy Ridge, nruab nrab ntawm ob tus dej loj ntawm Siberia - Uchura thiab Olekma.
yam ntxwv
Lub Aldan Highlands yog daim thaiv tectonic ntawm lub sijhawm Precambrian. Nws yog nyob rau ntawm Siberian platform. Cov qauv ntawm cov ntaub thaiv npog tectonic feem ntau yog Proterozoic shales thiab gneisses. Yuav luag txhua qhov chaw ntawm thaj chaw ntawm thaj chaw siab, tsim ntawm crystalline hauv qab daus, uas sawv cev los ntawm gneisses, quartzite thiab marbles, tuaj rau saum npoo. Cov pob zeb crystalline no yog overlain los ntawm cov khaubncaws sab nraud povtseg ntawm nplua granite. Nws yog tsim nyog sau cia tias txhua tus ntawm lawv tau tsim nyob rau hauv txawv geological lub sij hawm.
Aldan highland muaj du, du slopes. Tsuas yog nws sab qaum teb yog raug me ntsisfoundation.
Txoj kev cawm seej
Txoj kev nyem ntawm Aldan Highlands nws tus kheej yog sawv cev los ntawm lub rooj qis-stepped toj. Lawv qhov siab nruab nrab yog 800-1200 m. Qhov siab tshaj plaws yog lub roob uas tsis muaj npe, 2306 m siab. Ancient volcanic kev ua ub no muaj kev cuam tshuam zoo rau kev tsim cov kauj ruam nyem ntawm cov toj siab. Qhov tseeb tias volcanoes feem ntau tshwm sim nyob rau hauv qhov chaw no yog pov thawj los ntawm cov seem ntawm lawv cov dej num.
Orographically, cov toj siab yog elongated nyob rau hauv latitudinal kev taw qhia. Raws li nws qhov ntev, muaj cov kab ntawm tectonic faults ntawm lub platform, nyob rau hauv cov hav dej nyob.
Mineral peev txheej ntawm Aldan Highlands
Teb chaws toj siab no kawm tsis zoo. Ib qho kev cuam tshuam rau qhov no yog huab cua hnyav thiab thaj chaw permafrost. Tab sis txawm qhov no, nyob rau hauv lub xyoo pua xeem, nplua nuj mineral deposits tau pom nyob rau hauv lub cheeb tsam no. Tam sim no lub Aldan Highlands yog ib qho chaw uas yog "kub leeg" rau Yakutia. Hauv 20s. ntawm lub xyoo pua xeem, heev los ntawm kev sib tsoo, ib tug neeg yos hav zoov Yakut pom kub deposits nyob ze ntawm lub kwj deg. Raws li nws tau tshwm sim tom qab, cov no yog cov pob zeb kub loj tshaj plaws hauv Lavxias Federation.
Ntxiv rau cov tso nyiaj no, tooj liab thiab hlau ore, mica thiab pob zeb siv lead ua tau tshawb nrhiav thiab tam sim no tab tom khawb. Cov Aldan Highlands kuj muaj cov nplua nuj nyob hauv cov pob zeb. Nws cov deposits yog nyob rau sab qab teb txoj kab nqes. Txawm li cas los xij, kev siv thee tsuas yog qhov nyuaj ntawm no vim huab cua.
