摘要

斯洛伐克北部西部Tatra山脉Baranec山古生代片麻岩中的石英分选中出现了大型蓝晶石晶体(尺寸<15 cm)。蓝蓝晶石晶体与石英和斜长石共存。蓝晶石含有磷灰石、独居石包裹体。配子石、金红石、黑云母和逆行硅线石的过度生长。白云母和黑云母。蓝晶石晶体是迄今为止在塔特拉结晶地块或其他西喀尔巴阡山脉结晶岩芯中发现的最大的晶体。蓝晶石。矿物组合共存，标志着西特拉山海西期变质作用的HP期。

Megacrysts of kyanite from Baranec Mt., Western Tatra Mountains, Slovakia

Abstract Large crystals of kyanite (<15 cm in size) occur in quartz segregations in Paleozoic gneissses on Baranec Mt., Western Tatra Mountains, northern Slovakia. Blue kyanite crystals coexist with quartz and plagioclase. The kyanite contains inclusions of apatite, monazite. gamet, rutile and biotite and overgrowths of retrograde sillimanite. muscovite and biotite. The kyanite crystals are the largest found up to now in the Tatra crystalline massif or in the other Western Carpathians crystalline cores. Kyanite. with the co-existing mineral assemblage, is indicative of a HP stage duiing Hercynian metamorphism of the Western Tatra Mountains.
