麻扎塔格山对其南北侧风沙地貌的影响

麻扎塔格山位于塔克拉玛干沙漠腹地的和田河以西,北纬38°30′—38°40′,东经79°43′—80°48′,东西长120公里,南北宽2—4公里,高出山南平原200—300米。它的西侧是与麻扎塔格山结构、构造相似的古董山、罗斯塔格山,这一几乎连续的隆起把和田河西部的沙漠分为南北两部分。麻扎塔格山是由中上石炭系、二迭系和老第三系石灰岩、红色砂岩所组成。在该地区出露的老第三系乌拉根——卡拉塔尔组地层,中下部浅灰黄色钙质砂泥岩中夹有介壳层,含有贝氏牡蛎化石,在齐姆根组和阿尔塔什组的灰绿色泥岩、白云岩地层中含有双

The Influnce of Mazhatag Mountain on Wind Sandy Landforms in Its Two Sides

In this paper the impacts of Mazhatag Mt. on wind sandy landforms distributed in its south and north sides were mainly discussed. The results indicated: The laws of sand deposit and wind erosion in this area have been transformed with the mountain. The height of sand dunes, being generally higher and larger in the north of the mountain, but lower and smaller in the south, is relative to the height of the mountain in exponential curve. The sandy landforms influnced by the mountain evidently spread as 20__30 times as the mountain's height in the scale. Special flow field resulted from the mountain formed the special dune landforms in each sides.
