Galunggung volcanic rocks are included within the Galunggung Group and can be divided into old Galunggung formation, Tasikmalaya Formation and Cibanjaran formation. The firs formation represents rocks of old Galunggung stratovolcano (50.000 - 10.000 yrs. BP?), the second formation covers rocks erupted during caldera formation (4200 - 150 yrs. BP) and the third one comprises rocks in t822, 1894,…
