Angles of white flint stone on a black diabase by the bay of Edsvik. Diabase, also called dolerite is a dark volcanic rock that has formed in cracks of older rock. The density is decided by the cooling speed in the underground rock.
Flint is a sedimentary form of quartz and the white, or really off white yellowish, color comes from lime covering the actual flint. Anyway it is a hairless stone excellent to make sharp tools with if you crack it open.
