近些年来，随着我国地质勘查工作的快速发展，全国范围内产生了数量巨大的岩矿芯等实物资料，根据1990年颁发的《岩矿芯管理通则》的规定要求，由于岩芯增长数量成爆炸式增长，各岩芯产生及保管单位原有的保管库房已远远不能满足保管需求。因此，为了更有效的开展岩芯保管工作，根据“科学论证，慎重处置”的原则，按照规定的工作程序和技术方法对岩矿芯进行缩减已成为必然趋势。%Huge amounts of physical geological materials (such as drill cores)have been produced along with the rapid development of geological exploration in recent years.Due to the explosive increasing of the drill core amount,inventory capacity of production units and preservation departments could not meet the demands,according to the requirements of regulations issued in 1990 “drill core general management”.In order to carry out the preservation work of drill core effectively,reduction of drill core must be the inevitable trend.Furthermore,the drill core reduction work must follow the principle of “scientific proof and careful handling”and.
