金伯利岩的卫星影像识别标志及应用实例

金刚石矿是我国的急缺矿种,具有很高的工业价值和经济价值。但是,过去50年中国在寻找金刚石矿上始终没有取得突破。在科学理解金伯利岩火山地貌形态的基础上,利用卫星影像识别技术,建立一个地区金伯利岩的卫星影像识别标志,能够在金刚石矿靶区范围内有效地缩小目标。这些都是要建立在野外和室内反复认证的基础之上。本文以博兹瓦纳境内两个著名的金刚石矿,结合山东临沂和湖南常德地区的具体实例来推断金伯利岩的存在。在寻找金伯利岩时,理解金伯利质火山是玛珥-管道火山体是寻找金伯利质火山管道的基础,应重视对低平圆形地质体成因的研究。建立一个地区的小型圆形地质体的卫星影像识别标准是一个野外和室内反复验证和积累经验的过程。

Satellite image index of kimberlite and its application

Diamond deposit is important one for the development of Chinese economics, with highly demand in industr. However, in the past 50 years, China has not made a breakthrough in discovering it. Based on establishing the geomorphology of kimberlitic volcano, satellite image index is being recommended to establish by using satellite image data, which can effectively find the exclusive targets in a target area for possible diamond deposit, establishment of SII is a process that need repeated field and indoors checking. This paper illustrates some examples of diamond mines of Botswana, and possible targets in Linyi, Shandong Province and Changde, Hunan Province, where diamonds in alluvial are abundant. In the process of looking for kimberlite, understanding that kimberlite volcano is a maar-diatreme volcano, making knowledge foundation of looking for kimberlite, paying attention to the study of the genesis of low-flat-circular geological body, and establishing its satellite image recognition standard in an area, with field verification and topographic accumulation.
