Outline of Final Research Achievements |
I summarize results from two ophiolites (the northern Oman ophiolite of Oman and the Mirdita Ophiolite of Albania) and ophiolitic localities (the Talkeetna massif, Alaska) in order to investigate the maturing processes of arc systems, such as Nascent, Young and Mature stages, respectively. The main conclusions are as follows: (1) the high frequency of highly refractory harzburgite (+dunite and chromitite) caused by influx of slab-derived fluids, (2) silica enrichments resulting in increasing of pyroxenites in peridotites. These can be good indicators of arc-related magmatic modifications in the mantle. In Mature stage (Talkeetna), ultramafic rocks are formed by metamorphism from plagioclase-bearing crustal rocks. These rocks can be related those are delaminated from the lower crust part to the mantle.
