摘　　要：麦饭石是一种天然矿物药石,多用于医药保健、农业畜牧等领域。采用近代岩石学分析测试技术,对有中华麦饭石之乡称号的齐齐哈尔市碾子山区麦饭石的岩石学特征、矿物组分与化学成分、热学性质以及结构特性等进行研究测定。结果表明:碾子山麦饭石是一种具有斑状结构呈致密块状的闪长玢岩,其中,w(SiO_2)约64%,w(Al_2O_3)约16%,里特曼指数σ=2.9<3.3。含Sr,V等对人体有益微量元素,主要矿物有斜长石、钾长石、石英,含少量风化蚀变产物(如角闪石、绿泥石和蒙脱石等粘土矿物)。在1 000℃条件下,碾子山麦饭石仍保持良好的热稳定性。碾子山麦饭石具有海绵状多孔结构,孔径以6μm以上的大孔为主。大孔结构使其既可作为优良吸附剂应用于环境领域,同时也便于其中微量元素的溶出,有望作为制药载体等得到广泛应用。Maifan stone is a natural medical stone and used in many fields, such as medicine, health care, agriculture, animal husbandry. The mineral and chemical composition, microstructure, thermal performances and micro-structural properties of Nianzishan Maifan stone are investigated by modern analytical techniques. It is showed that the Nianzishan Maifan stone is a structurally compact porphyritic calcium-alkaline magmatic rock （Rittman index., a = 2.9 〈 3.3） with 64% of w（SiO2）, 16% of w（Al2O3 ）. The Nianzishan Maifan stone is mainly composed of feldspar, quartz, with minor weathered and altered products （montmorillonite, etc. ）, containing various beneficial trace elements. Its thermal stability is within 1 000℃ and possess a spongy porous structure with dominant pore size above 6 μm, so it can be used as excellent adsorbent in environmental field, and also as good drug carrier in pharmacy.
