| 中文摘要: |
| 铬铁矿床成因可分为两大类:岩浆铬铁矿床和地幔变质橄榄岩残、滞留铬铁矿床。后者直接受上地漫岩熔融程度所制约。而岩浆铬铁矿床的形成除决定于上地幔岩熔融岩浆总成分外,还受岩浆分异结晶作用、岩浆就位的地质条件和规模所决定的结晶速度和状态直接影响。 |
| 英文摘要: |
| Cr ore deposits are genetical divided into 2 types ie. magmatic type and relic and stagnated type of metamorphosed mantle peridotite. The later is controled by melting degree of the upper mantle rock. The former is not only controled by general composition of melting magma from the upper mantle rock but also by crystalization velocity which is govened by differentiation crystalization of the magma and it's emplacemcut. |
