| 摘 要： | 察尔汗盐湖的盐类沉积,东西长164km,南北宽13～44 km,面积4704.8km~2,自西向东分为4个区段。它们的盐类沉积统称为含盐系,其中夹有5层碎屑层,把含盐系分隔成5个含盐组。该盐湖钾矿分为固体钾矿和液体钾矿两种。前者储量小,品位变化大;后者储量大,品位变化小。固体钾矿赋存于各盐层中,共有8层矿。液体钾矿具有明显的分层性,上层品位较高。

DISTRIBUTION REGULARITY OF THE SALT AND POTASH-ORE BEDS IN CHARLEHAN SALINE LAKE |

| Abstract: | The saline deposits in Charlehan is 164 km long from east to west,13-44 kmwide from south to north,with an area of 4 704.8 km~2.They can be divided into 4sections from east to west.The 5 more stable clastic beds in the salt-bearing sequencesubdivided the later into 5 salt-bearing formation.In Charlehan,there exists twokinds of potash-ore-solid ore and liquid ore.The former is small in reserve andmore variable in grade,while the later is large in reserve and less variable in grade.In occurence,the solid potash-ore exists in every salt bed,8 layers in total.Theliquid ore has obvious stratification,with the upper layer having higher grade. |
