KARAKTERISTIK LAVA DAN KEMUNGKINAN PEMANFAATANNYA SEBAGAI BAHAN GALIAN KONSTRUKSI DAERAH MALIMPING KABUPATEN BANDUNG, JAWA BARAT

Abstrak

This research background are potency and limitation aspects in construction material resources
application in southern part of Bandung Regency. The problem of research is role of lava characteristic
in application designe as construction material resources. This research use deduction method with
probabilityapproach. Result of research show lava at Malimping area and surrounding have characteristic
are grey-black, fine to intermediate texture, basaltic. A part of lava has sheeting joint and another
massive. Based on petrographic analysis, a part of lava has a little alteration. That condition showed by
a part of pyroxene had altered to chlorite. Result of chemical and physical analysis of rock show lava at
Malimping area and surrounding is basalt. Potency of lava at Malimping is significane as contruction
material. Based on morphometry calculation and lava outcrop spreading, lava potency estimated
44.573.500 m3. Nevertheless, that all potency can’t used because it spread in upper area of Citarum
river. Based on lava characteristics, outcrop position, regulation of landuse and trend of community
need so that basalt lava potency used as dimention stone. That using can up value of contruction
material so that income of community in that surrounding area can up too.
