Aldan Highlands: incazelo, izici, isithombe

Uphi i-Aldan Highlands futhi yini? Kule mibuzo ungathola izimpendulo uma ufunda imininingwane echazwe kulesi sihloko.

Indawo yendawo

Engxenyeni yeRiphabhlikhi yanamuhla yeSakha yinqaba, ebizwa ngokuthi i-Aldan. Leli fomu lokukhulula liphakeme ngokuphakama. Uma ubheka ibalazwe, itholakala emaphethelweni asenyakatho eStanovoi Ridge, phakathi kwemifula emibili yaseSiberia - Uchur no-Olekma.

Isici

I-Aldan Plateau iyisihlangu se-tectonic seNkambiso yokuQala. Itholakala esiteji saseSiberia. Isakhiwo se-tectonic isihlangu sakhiwa ikakhulukazi ngama-proterozoic shales nama-gneisses. Kungakhathaliseki ukuthi kuyo yonke indawo ensimini yezindawo eziphakeme, ama-crystalline basements afaka phezu komhlaba, amelwa ama-gneisses, ama-quartzites, nama-marble. Lawa ma-crystalline agcwele ama-granite amahle. Kubalulekile ukuphawula ukuthi ngamunye wabo wakhiwa ngezikhathi ezahlukene zezwe.

I-Aldan Highlands inezintambo ezibushelelezi, ezibushelelezi. Uhlangothi lwalo olusenyakatho kuphela oluhambisana nokubeka okuncane kwesisekelo.

Izici zenkululeko

Ukukhululeka kwe-Aldan Highlands ngokwayo kuboniswa ngamagquma aphansi ase-stolovo. Ukuphakama kwabo isilinganiso kuyinto 800-1200 m. Iphuzu eliphakeme yilona intaba, elingenalo igama, ngokuphakama 2306 m. Umsebenzi wasendulo oshaywe yizintaba-mlilo waba nethonya elikhulu ekubunjweni kokukhululeka kwe-upland. Iqiniso lokuthi kule ndawo kuqhume ukuqhuma kwemifucumfucu, imidwebo esele yomsebenzi wayo ikhuluma.

Orographically, lezi ziqhingi zihlangene ngendlela elandelanayo. Kuyo yonke ubude bayo, kunemigqa yeziphambeko ze-tectonic zesikhulumi, lapho kutholakala khona izigodi zomfula.

Amaminerali e-Aldan Plateau

Isizinda salesi siqhingi asiqondwa kahle. Isithiyo kulokhu yisimo sezulu esibi kanye nezindawo ezihamba phambili. Kodwa naphezu kwalokhu, kulezi zinsuku ezedlule i-deposit ecebile yamaminerali itholakala kule ndawo. Manje i-Aldan plateau yindawo 'eyi-golden vein' yeYakutia. Ku-20-ies. Ekhulwini lokugcina, ngengozi, umzingeli wase-Yakut eduze nomfudlana wathola idiphozi yegolide. Njengoba kwenzeka kamuva, lezi yizimbiza ezinkulu zegolide ze-Russian Federation.

Ngaphandle kwalezi ziphopho, ithusi nethusi ye-iron, i-mica ne-crystal crystal iye yahlolwa futhi yakhishwa ensimini yendawo. Futhi, i-Aldan Highlands icebile ngemali yamalahle. Izitokisi zalo zikhona emthambekeni oseningizimu. Noma kunjalo, izimayini zamalahle lapha kunzima ngenxa yezimo zezulu.
