1.1 tatanan

basalt formulir nalika lahar tekan lumahing bumi near vulkanik. suhu lava iku antarane 1100 1250 ° c nalika nemu menyang permukaan.

amarga kanggo ngganti ing kondisi lingkungan, rocks sing digawe panas lan pressurized jero nang permukaan bumi. pseudotachylite kawangun saka panas nemen disebabake magma utawa dening tabrakan kuat lan gesekan lempeng tektonik.
