| | MYRMEKITE 4 of 50 |
 | | In southern Finland, 9 km northeast of Alastaro (75 km north-northeast of Turku), pods and veins of megacrystal granite, containing K-feldspar crystals (2 to 3 cm long), occurs in sharp contact with gabbro. |
 | | At Alastaro, it is clear that the K-feldspar is primary instead of secondary because it is deformed and fractured, and that the myrmekite is secondary, because it is undeformed in the fractures. |
 | | Myrmekite is also found on borders of deformed plagioclase in the gabbro, in the interiors of fractured K-feldspar megacrysts in the granite, and in Carlsbad-twinned euhedral plagioclase inclusions in the megacrysts. |
