Archean felsic volcanic rocks lenticular fiamme. When hot pumice deposits on a cool surface, it is rapidly cooled, recrystallised and welded into quartz with flame-like ending tips. The eutaxiitc texture represents a hot vapour-phase emplacement of the fragmented volcanic materials on the Earth's surface. Flow bands are present in massive, uniform felsic lava flow units. When the viscous lava flow encounters a surface, friction drags the mobile lava and forms internal banding. Structureless hyaloclastite is commonly found in Archean felsic volcanic rocks. In submarine environments, water quenches and cools lava rapidly during volcanic eruption. The flow is fragmented and form glassy volcanic breccia. The
Bait (luring substance) Bait (luring substance) Bait is any substance used to attract prey, e.g. in a mousetrap. The term is especially used with regard to catching fish. Traditionally, nightcrawlers, insects, and smaller fish have been used for this purpose. Fishermen have also begun using plastic bait and, more recently, electronic lures, to attract fish. Because of the risk of transmitting Myxobolus cerebralis (whirling disease), trout and salmon should not be used as bait. There are various types of saltwater baits that are natural. Studies show that natural baits like croaker and shrimp are more recognized by the fish and are more readily
