Abstract:

The results of regional geological survey, prospecting and exploration indicate that Bac Giang is a province with potentials of minerals making normal constructional materials, especial brick-clays and pebble-granule- sand. During doing the project of Ministry of Education and Training with code number of B2009-02-77TĐ, the authors have discovered and defined two limestone occurrences and one riolite rock occurrence at Cam Son commune, Lục Ngan distrist; two 2 new conglomerate occurrences at Luc Son commune, Luc Nam distrist; and an yellow sand body concerning to I level terrace, distributing in Cau River valley, Hiep Hoa district. These minerals all meets demands of making constructional materials, especial yellow sands can be used in making combined materials in cement. Potential resource of carbonate making constructional materials is about 17 mil. m3; brick-clays - 465 mil. m3; constructional sand - 91.14 mil.m3. Mineral resources making normal constructional materials play important role in development of economy - society in Bac Giang province, therefore they need planning and organizing exploitation, using and protecting environment effectively
