广西铝土矿遥感综合成矿预测及资源总量估算

前人在已知矿床、点的基础上对广西铝土矿做过系统的成矿预测及资源总量估算，但原有工作限于储量级别要求，划入预测区的范围较小，部分有矿层分布的区带未圈出，又参与资源总量估算的块段尚有向外延伸部分。通过遥感综合方法，在原有基础上扩大预测区，增加三水型铝土矿预到区，并对已知块段外延矿带、新增预测区进一步估算其资源总量，较全面地解决了资料不完整地区的铝土矿资源量估算问题。

SYNTHETIC REMOTE SENSING METALLOGENIC PROGNOSIS AND TOTAL AMOUNT ESTIMATION OF BAUXITE RESOURCES IN GUANGXI

Although the predecessors have finished systematic metallogenic prognosis and total amount estimation of bauxite resources base on known deposits (or points), owing to the demand of reserves grades, the ranges delimited into prognosis regions are relatively small. Some regions which ore-layers are distributed aren't delineated and there are still some uncalculated out-stretch-parts in the regions selected to estimate total resources amounts. Through adopting synthetic remote sensing method, enlarging ranges of prognosis regions, adding new prognosis regions of gibbsite and estimating the total resources amounts of out-stretch-parts and new-add ones, the author fairly solves the problem of estimating total resources amounts in incomplete material areas.
