FRACTURE (VEIN) MINERALS IN AMPHIBOLITE ROCKS ON THE SOUTHERN EDGE OF THE KRIVAJA–KONJUH MASSIF (BOSNIA AND HERZEGOVINA)

Mevlida OPERTA¹

One of the impressive geological formations in Bosnia and Herzegovina is part of the Dinarides Central Ophiolite Zone, known in literature as the Bosnian Ophiolite Zone. Within the ophiolite zone, there are 6 ophiolite complexes in Bosnia among which the Krivaja-Konjuh Ophiolite Complex stands out with its size.The paper presents the results on research to date of fracture (vein) minerals in the Bosnian Ophiolite Zone, with accent put on research of vein (fracture) minerals on the southern edge of the Krivaja–Konjuh Ophiolite Complex. The following were conducted in the research on fracture (vein) minerals: an optical examinations by polarization microscope, x-ray examinations and chemical analysis by an electronic microprobe. The following were determined as fracture (vein) minerals in amphibolite rocks: prehnite, zeolite minerals (laumontite, thomsonite, mesolite and analcime), epidote-clinozoisite, chlorite, calcite, then plagioclases, quartz, garnet minerals and corundum. In contact zone between these rocks and metadiabases, the followings were determined: prehnite, epidote and subordinate clinozoisite and quartz.
