New Data on Mineralogy, Petrology and the Origin of Calc--Silicate Rocks from Novo Selo-Kriva Lakavica, Eastern Macedonia

The paper presents the results of the latest research carried out on calc– silicate rocks from Novo Selo – Kriva Lakavica, Eastern Macedonia. One hun- dred samples were collected for research. Chemical, optical and X-ray analyses were performed. The results show that the dominant material in these rocks is calcite. The following minerals were also present: diopside-hedenbergite, augite, actinolite, pargasite, K-feldspar, plagioclase, quartz, titanite, vesuvian- ite, clinozoisite, andradite–grossular, scapolite and prehnite. These mineral associations and the regional distribution of calc–silicate rocks from Novo Selo – Kriva Lakavica indicate regional metamorphic conditions of origin. Such min- eral associations have been described in many regional metamorphic complexes
