The petrology and geochemichal characteristics of metamorphites in between Budakli-Bolukyazi (Hizan-Bitlis)

This work as a post graduate thesis comprises metamorphic rock's petrography, petrology and geochronology in between Budaklı and Bölükyazı vilage (Hizan-Burdur). Investigated area is inside Bitlis massive and Southeastern Anatolia Thrust Belt. These massive is biggest massive as aresult of collision between Avrasia and Arabia-Aphrica plate. Petrographical and geochemical analyses show that Karakuş formation comprise of amphibolite, gneisse, micaschiste, quarzfeldispatic gneisse, biotite metagranite, Bitlis groupe comprise of marble, quartsite, quarzschiste, micaschiste and phylite, Gökçimen also comprises flysch, Kuyutu formation comprises chloritoid-chlorite schiste, quartsite, marble and metaschell, Çadırdağ formation comprises sedimanter and volcanic rocks. These formations cover slope wash and aluvions. Geochemichal character of metamorphic rocks shows calcalkalen magma type. It is Light REE as regard Hight REE of mineral samples. These changes in REEs indicate hydrothermal effect. The negative Eu anomalies in all rocks can stems from contamination in crustal continental, conduct away of feldispat, sediman mixing by sedimanter dehydratation in magmaetc. The investigate show that Bitlis metamorphic's rocks is characters with basic origin and little contamination from crustal continental. Sm-Nd isotopic age is Campanien as a 80.508±0.11 Ma and 79.293±0.10. The geochronologic value is peak metamorphism age after northern subduction of Arabia crustal shell. Mineral paragenesis show change from amphibolite to greenstone facies. The low temperature metamorphism is ensued exhumation of massive.At different In different pressure-temperature conditions , only a smallpart of the BitlisMetamorphics is crumblend and a large part shows that the mafic rocks are formed as aresult of dynamotermal metamorp hism under the influence of tectonic activities. Key words: Bitlis metamorphite, Sm-Nd geochronology, Dinamothermal metamorphism
