| 摘 要： | 根据最大似然法应用ＴＭ影象数据，对拉斯曼地区米勒半岛进行岩性自动识别分类。结果提取出该区的５种主要岩石类型即：１．片麻状花岗岩；２．正长花岗岩；３．富Ｆｅ、Ａｌ片麻岩；４．混合岩；５．条带状混合岩。说明用自动分类法进行地质岩性填图在该地区是可行的。它为南极地质工作提供了一种新的方法，初步工作表明，该方法分类速度快，省时省力，能减少大量的野外工作。为利用遥感资料进行地质工作展示了良好的前景

| Abstract: | According to Maxium Likelihood Method and TM data, we conducted the automatic taxonomy of rock in the Mirror Peninsula of the Larsemann Hills, East Antarctica. Five kinds of rock were identified. They are: ①Gneissic Leucogranite, ②Syenogranite, ③High Al Fe gneisses,④Migmatite,⑤Striped migmatite.The reliability is 82 precent. This method is useful in Antarctica and it is economic and efficient method.Development of satellite borne polar remote sensing in the geology has good prospects. |
