芬兰已按若干计划对其领土进行了区域地球化学填图。填图中特别注意了冰川沉积物和有机质(沼泽腐殖质)取样以及水文地球化学取样。个别地区工作做的很细。工作是按以下比例尺进行的:1:2000000(细密度—300km~21个样),1:2000000(4km~21个样)。数据库中加进了1057个岩石地球化学样,水化学样和从0.7m深处土壤中采集的生物化学样品的分析结果。在此基础上绘制了芬兰地球化学图集。在1:2000000 例尺测量过程中采集了取自1.5-2.5m深的8万个样品,进行了细粒级分析,合并成了3-5个
Finland has conducted regional geochemical mapping of its territory in accordance with several plans. Special attention was paid in the mapping of glacier sediments and organic matter (swamp humus) sampling and hydrogeochemical sampling. Work done in individual areas is very small. Work is carried out on the following scale: 1: 2000000 (fineness -300km ~ 21 samples), 1: 2000000 (4km ~ 21 samples). The database incorporates analysis results of 1,057 rock-geochemical samples, hydrated samples, and biochemical samples taken from 0.7 m deep soil. Based on this, Finland’s Atlas of Geochemistry was drawn. 80,000 samples taken from 1.5-2.5m depth were collected during the 1: 2,000,000-foot survey and fine-grained analysis was performed and merged into 3-5
