Munganditaurirewo here uko riri ndarama mhangura

tinogona overenga hunonzi, umo dzine underlain kubudikidza nendarama mhangura, huwandu reserves ayo imwe munda, kusarudza kuvaka kambani mugodhi zvinobatsira pano? Mushure ubanguranyika, kuchera zvakadzika matsime uye ubanguranyika ezvimbambaira kutora makore, uye vanopfuura chiuru chimwe zvemadhora. Pane zvikonzero pairi zvokufungidzira kuvapo ari mukati bwenyika inokosha simbi muura? Haiwa, kwete zvakasikwa "yokuwana" kutsvaka deposits goridhe vanhu asati tega. Kunyange zvazvo nguva refu akafunga pamusoro nyaya iyi.

Gold Mboroma kunoda kunzwisisa geologist, kufemerwa, anenge iwe. Mune imwe nzvimbo zvinokosha uye dendrites anenge kwemvura pasi petsoka dzake, ukuwo mumwe ane zvose rinotevera zviratidzo, uye dombo iri hapana aitodada zvinokosha simbi. Kuti tinzwisise kwakabva nyaya iyi nokuti vanhu vaida zvinhu kunoita kudzidza kwemasayendisiti kuitika mudumbu nyika kuti kudzika anoverengeka makumi makiromita.

Earth igneous basa nokudzinga microcracks makuru uye Kunetsana mumatombo Hot mhinduro vakasara pabwe pamadziro migero izvi precipitate kubva feldspars, Goldstone, sarufa yeimwe vane simbi dzakasiyana-siyana. Gold mhangura, Platinum uye sirivha zvinogonawo kuva pakati pavo. Kazhinji Nuggets isirivha kwake. Kana chena simbi mukuru 25%, saka akadana ibwe nesirivha. Kunewo chizvarwa sirivha, iyo ine admixture chendarama. kyustelity ichi chine yeyero simbi kungava kusvika 10%. The makemikari anoumba mhinduro, vakauya simbi dzinokosha apasi akaturikidzana ari goko kuti kudzika 5-7 makiromita vanoverengeka makumi ezviuru metres, zvinoratidza kuti vanofanira kutarisa mune sulphide uye chloride runyararo.

Asi ruzivo urwu hakuiti kutiunzira pedyo chinokosha: kutsvaka deposits nendarama hunonzi. Chloride uye sulphide zvinyorwa zvizhinji, asi zvinodiwa simbi akawanikwa kwete chero pavo. Zvinogona vaifungidzira kuti fuma inotifadza yakaumbwa kubva yekare alluvial sediments yamakungwa, akavigwa pasi makiromita akawanda panyika. Ikoko, achifuridzirwa mukuru tembiricha uye kumanikidzwa, zvakanzi yakarukutika kuti mvura magma vakapfuura Kunetsana uye haagoni Rakasimbisa muchimiro esimbi kana zvinokosha. Asi pfungwa iyi dzesayenzi haritipi rinoshanda kushandiswa.

Ngatiedzei kuenda rumwe nzira: kuziva zvicherwa list, iyo kazhinji anoenda goridhe mhangura. shamwari dzake dziri dzimwe anokosha nesimbi - sirivha, Platinum, palladium, iridium, ruthenium, osmium uye rhodium. Uyewo pedyo intergrowth pamwe splashes endarama kuitika zvishoma vanokudzwa erudzi: Goldstone, argentite, pyrite, galena, adular, albite, neametisi. Asi dambudziko iri kuti satellites izvi kazhinji havana chimwe zviyo goridhe, uye saka havagoni kushumira isu senhungamiro ari kutsvaka kuti kukosheswa core.

Gold kuchera muRussia kwenguva refu akanga kuitwa alluvial deposits, kuti ndipo zvichaita Leach pemvura nzizi. Uye kana dzimwe nyika wakafunga itsva kutsvaka maturusi uye kukura zvigadzirwa, tine pfuti prospector akaramba muchimwiro hungu nomusero. Sezvineiwo, edu asvinure dzezvimwe pamusoro deposits izvi richiri zvikuru. Vakati vaneta ari Urals, rakakura accumulations kuti alluvial deposits dzakafukurwa kuSiberia uye kuFar East.
