新疆和田普魯火山

普魯(lu)火(huo)山(shan)(shan)實為(wei)(wei)火(huo)山(shan)(shan)熔(rong)(rong)巖(yan)(yan)(yan)(yan)層(ceng)(ceng)(ceng)(ceng)，來自于(yu)南部的(de)昆侖山(shan)(shan)。活動(dong)時間約(yue)143萬年(nian)前。火(huo)山(shan)(shan)熔(rong)(rong)巖(yan)(yan)(yan)(yan)層(ceng)(ceng)(ceng)(ceng)分布于(yu)克里雅河(he)中游(you)兩側的(de)高(gao)階(jie)地(di)上(shang)(shang)(shang)，火(huo)山(shan)(shan)熔(rong)(rong)巖(yan)(yan)(yan)(yan)分兩層(ceng)(ceng)(ceng)(ceng)，下(xia)層(ceng)(ceng)(ceng)(ceng)厚(hou)7米(mi)(mi)，為(wei)(wei)火(huo)山(shan)(shan)集塊(kuai)巖(yan)(yan)(yan)(yan)和致(zhi)密塊(kuai)狀熔(rong)(rong)巖(yan)(yan)(yan)(yan)，覆蓋在砂(sha)礫(li)上(shang)(shang)(shang)，接(jie)觸面有礫(li)石(shi)層(ceng)(ceng)(ceng)(ceng)被烘(hong)烤痕跡(ji)；兩層(ceng)(ceng)(ceng)(ceng)間夾12.3米(mi)(mi)厚(hou)的(de)礫(li)石(shi)層(ceng)(ceng)(ceng)(ceng)，上(shang)(shang)(shang)層(ceng)(ceng)(ceng)(ceng)熔(rong)(rong)巖(yan)(yan)(yan)(yan)厚(hou)20米(mi)(mi)，為(wei)(wei)集塊(kuai)巖(yan)(yan)(yan)(yan)、致(zhi)密塊(kuai)狀巖(yan)(yan)(yan)(yan)和氣(qi)孔狀巖(yan)(yan)(yan)(yan)石(shi)。上(shang)(shang)(shang)、下(xia)層(ceng)(ceng)(ceng)(ceng)熔(rong)(rong)巖(yan)(yan)(yan)(yan)，均形(xing)(xing)成于(yu)第四紀早更(geng)新世，屬不同時期的(de)兩次火(huo)山(shan)(shan)噴發的(de)玄(xuan)武巖(yan)(yan)(yan)(yan)（粗安巖(yan)(yan)(yan)(yan)），玄(xuan)武巖(yan)(yan)(yan)(yan)組成階(jie)地(di)陡崖，形(xing)(xing)似眾(zhong)多奇異造型(xing)的(de)怪(guai)獸(shou)傲視遠方，蔚為(wei)(wei)壯觀(guan)。

火山巖覆蓋于河流6級階地的砂礫石層上，其上覆蓋風砂質黃土層。火山熔巖分兩期，均屬早更新世火山熔巖流。兩次火山活動都在南部的昆侖山高山地帶，且規模巨大，巨大的火山巖漿象洪流一樣，流出山地，覆蓋于山前沖洪積傾斜平原的礫石層上。它對研究青藏高原及昆侖山的形成及環境演化意義重大。
普魯火山處于原始的保存狀態，因其在國內(nei)外有名(ming)，常有學者(zhe)前來考察研究。
