吉林省敦化地区泥炭成矿类型及性质

Type of forming peat ore and character of peat in Dunhua, Jilin province

吉林省敦化地区泥炭矿点 1 1 3处 ,储量约 1 .0 5× 1 0 8m3,质量和储量在吉林省市、县中居前列 .通过对敦化大桥乡裕家泥炭地的科学考查 ,在前人研究的基础上 ,探讨了其成矿类型和泥炭理化性质 .结果表明 :本区成矿类型有 :沟谷型、沟源洼地型、河漫滩型和堤外洼地型 .泥炭有机质、腐殖酸含量高 ,灰份含量低 .

There are 113 peat ores and the reserves are 1.05×10 8 m 3, in Dunhua, Jilin. The reserves and quality of peat are the first in all counties in Jilin. The type of forming peat ore and peat character are discussed in the paper. The results show that the types of peat ore are divided into channel, channel headstream, floodplain and outside bank depression based on the factor of physiognomy. The content of organic matter and humic acid are high while the content of ash is low in peat in this area.
