I thought the rock of Koli was supposed to be quartzite? If this category correctly named? --Periegetes (talk) 14:18, 10 May 2020 (UTC)[reply]

related to Category talk:Granite formations of Ukko-Koli. The granite also consists of quartz. We may need geological expertise here--Estopedist1 (talk) 06:20, 11 May 2020 (UTC)[reply]
I consulted wikipedia and it seems quartz is a mineral, quartzite and granite are rocks (kivilaji), quartzite being distinct from granite. Since I an not a geologist, will not change the category, but am fairly confident the category names should be changed and the Koli categories recategorized. --Periegetes (talk) 14:31, 13 December 2022 (UTC)[reply]
