摘要
以铁岭县湾龙背地区的钾长石矿为例,研究了辽北地区伟晶岩型钾长石矿的分异相带特点及空间分布规律。指出具新太古代壳源岩浆成因的钾长石分异相带明显,可分为内中外三个相带,其中内部相带的块体状钾长石、中间相带的团块状具文象结构的钾长石质量好,并在对国内的钾长石的市场潜力分析的基础上,指明了辽北地区钾长石矿的开发利用方向。
This paper deals with differentiation and spatial distribution ofpegrnatite type K-feldspar deposits in north Liaoning by the example of the Wanlongbei K-feldspar deposit. The study indicates that Neoarchean crust-derived magmatogenic K-feldspar may be divided into endozone, middle zone and exozone. Massive K-feldspar in the endozone and graphic K-feldspar in the middle zone are good in quality. Exploitation of K-feldspar in north Liaoning is discussed.
