\n\tGraniit on levinuim kivimt\u00fc\u00fcp maakoore pindmises osas ehk nn graniitses kihis ja seda ka Eesti aluskorras ja r\u00e4ndkivide seas. Suur osa (ligi 80%) suurtest r\u00e4ndrahnudest Eestis koosnevadki graniidist (foto 4).<\/font>\n<\/p>\n

\n\tGraniitide r\u00fchma kuuluvad ka\u00a0rabakivid<\/b>, mis on v\u00e4lja eraldatud peamiselt nende omap\u00e4rase struktuuri t\u00f5ttu (fotod 6, 7, 8). Neis esinevad roosad kaaliump\u00e4evakivide suured kristallid ja \u00fcmardunud kvartsiterakesed (l\u00e4bim\u00f5\u00f5duga kuni 6 mm). Oma eba\u00fchtlase struktuuri t\u00f5ttu on rabakivid kergesti murenevad ja ehituses neid seet\u00f5ttu ei kasutata.<\/font>\n<\/p>\n
