This study concern the quaternary geology, geomorphology and sedimentology of the intramontane Bandung basin, West - Java, Indonesia. A comprehensive analysis of the sequence of lacustrine, alluvial and volcaniclastic sediments in the basin form the basis for a reconsstrution of the Late Quanternary geologic and morphologic evolution of the Bandung basin area and for an evaluation of the geolog…
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,…
