Lub hauv paus ntsiab lus tsim ntawm ntuj graphite tsuas yog suav nrog ob theem: carbonaceous theem thiab txhawb theem thiab metamorphic avalization theem. Ua ntej tshaj plaws, cov peev txheej ntawm cov khoom siv carbonaceous yog feem ntau yog cov carbon carbon thiab cov organic carbon thiab cov organic carbon monocon occup thiab micro-ancient tseem nyob rau hauv dej hiav txwv prescive; Inorganic carbon feem ntau yog los ntawm carbon-muaj cov tshuaj inorganic xws li cov pob zeb carbonate tsim nyob rau hauv lub nkoj marine. Cov roj carbonaceous cov ntaub ntawv sau thiab raug faus rau ntawm lub seabed, sib sau cov roj carbon-nplua nuj sedimentary txheej. Tom qab, thaum lub zog ntawm lub ntiaj teb cov phiaj, cov sedimentary me me tau txav mus rau qhov tob crust. Qhov kub thiab txias thiab kev kub siab ib puag ncig ua rau cov khoom siv hluav taws xob tawg sai thiab ua kom haum thiab maj mam muaju graphiteryu. 1. Kev tsim cov kev cai ntawm lub ntuj graphite muaj qhov kub thiab siab. Qhov chaw kaw ntawm qhov kub thiab kub siab yog qhov tseem ceeb rau cov khoom siv roj carbonaceous rau hauv graphite, thiab lub sij hawm muaj lead ua ke yog qhov tseem ceeb hauv kev teeb meem. Tshwj xeeb, roj av yog hais txog cov txheej txheem uas high-siab gase-crystalline graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite graphite Gracite Metamorphians hais txog cov khoom sib sib zog nqus me nyuam cov khoom lag luam tau los ntawm cov pyrolysis ntawm cov thee lossis asphalt hauv stratum nyob rau hauv kev kub siab thiab txawv txav kub.
Kev faib ntawm ntuj graphite tseem dav heev. Lub ntiaj teb cov pov thawj muaj txiaj ntsig ntawm cov duab ntuj muaj kwv yees li 280 lab tons, thiab cov cuab yeej cuab tam tau kwv yees li 81 lab, suav rau txog 1/4 ntawm lub ntiaj teb tag nrho. Tuam Tshoj cov kab ke graphite yog feem ntau concentrated nyob rau hauv heilongjiang, shandong, sab hauv Mongolia thiab Hubei. Ntawm lawv, Heilongjiang yog qhov loj tshaj crystalline graphite reservation xeev nyob rau hauv kuv lub teb chaws, suav nyiaj txog li 2/3 ntawm lub teb chaws Crystalline cov chaw khaws cia.
Tsis tas li ntawd, ntuj graphite feem ntau coexists nrog quartz, feldspar, thiab lwm yam, lossis yog tsim nyob rau hauv tob me ntsis thee seams.
