泥火山,顾名思义是由泥构成的火山。说是泥,是因为它的的确确是由黏土、岩屑、盐粉等泥土构成;说是火山,却又不是通常意义上的火山。通常所说的火山最基本的特征是由岩浆形成的,并具有岩浆通道;而泥火山则是由泥浆形成的,不具有岩浆通道。不过,泥火山不仅形状像火山,具有喷出口,还有喷发冒火现象。新疆乌苏泥火山,分布在乌苏西南的天山北麓山谷里。正在活动喷发的泥火山呈现为一眼眼泥泉,一口口泥潭,它们多呈圆形,个体不大,直径从几厘米到2米,星散地分布在方圆约半平方公里的山坡和谷地里。泉潭中的泥浆表面不时咕嘟咕嘟冒泡,犹如大地在沸腾。泥浆散发出带有臭味的沼气、硫化氢等气体,有的 Mud volcanoes, as their names suggest, are volcanic mud. It is mud because it really consists of clay, rock debris, salt and other dirt; it is a volcano, but it is not a volcano in the usual sense. The most basic feature of a volcano is usually formed by magma and has magmatic channels. Mud volcanoes are formed by mud and do not have magmatic channels. However, mud volcanoes are not only shaped like volcanoes, but also have vents and eruptions. Wusu mud volcanoes are distributed in the valleys of the northern foothills of the Tianshan Mountains southwest of Wusu. Mud volcanoes that are erupting at the event are presented as a muddy eye and a quagmire. They are mostly round in shape. They are small in size, ranging in diameter from a few centimeters to 2 meters. Stars are scattered in hillsides and valleys with a radius of about half a square kilometer. The surface of the mud in Quantan is buzzing and bubbling, like the earth is boiling. The mud emits gas with odor such as biogas and hydrogen sulfide, some
