建国50年来我国金红石矿产地质勘查及研究历史的回顾

我国金红石矿床地质勘查可分为 1949～ 196 6年、196 7～ 1976年、1977～ 1985年、1986～ 1999年四个阶段 ,实行金红石专门找矿的最后一个阶段发现矿床的速度远高于综合找矿的前三个阶段 ,共发现矿床 5 9处 ,探明储量 1亿t。相应的系统地质研究分为 1980～ 1989年初步研究、1990～ 1999年深入研究两个阶段。成矿理论体系初步形成 :矿床有 11个成因类型、5个成矿区带 ;矿床主要在变质岩地区沿深大断裂分布 ;成矿时代主要为晚元古代末期、泥盆纪、中生代及第四纪 ;成矿主要与板块的三次活动有关。

REVIEW THE 50 YEARS OF CHINESE RUTILE MINERALS EXPLORATION AND RESEARCH

China's prospection for rutlie deposits has gone through four stages: 1949～1966, 1967～1976, 1977～1985 and 1986～1999. The final stage, aimed at specialization in ore-hunting, more strongly speeded up prospection process than did the other three stages set for comprehensive ore searching, totally finding 59 deposits with a total of proven reserves up to a hundred million t. The general studies of deposit geology were performanced in the 1980~1989 period whereas the 1990～1999 saw a thorough investigation into the deposits of their kind. The works of the two periods contributed to the establishment of theoretical metallogenic system for the deposits, according to which they were grouped into 11 metallogenic types, respectively belonging to five different metallogenic provinces or belts. The deposits are characteristic of the distribution along deep faults in domains of metamorphic rocks, the metallogenic epoches of the end of Proterozoic, Devonian, Mesozoic and Quaternary, and the relation to three stages of plate movements.
