Özet:

 


In basaltic volcanics at Tekirdağ
region (Thrace), peridodit(ic) xenoliths such as harzburgite and dunite thought
as parts of upper mantle has been found. Petrographically, the bazaltic lavas
are olivine-basalts showing a primary paragenesis including mainly plagioclaze.
olivine. augite. magnetite and scarcely hypersthene as well the secondary
minerals at important degrees locally. On the other hand, geochemically they
correspond to the alkaline basalt, trachybasalt basanitic rock types.
Peridodite xenolithenclosing Hacıköy and Balabanlı and excluding Muratlı
basalts also differ in both major and trace element contents. Including olivine
(forsterite). enstatite, Cr-spinel and scarcely diopside, the peridodite
xenoliths are typically protogranular and partly grading into porphyroclastic
in fabric. Magmatic textures are well preserved. Displaying no foliation or
lineation. those have coarseto huge grain sizes. Bandings resembling twinning
and deformation lamellas imply the mechanical effec and are characteristic for
the olivines and pyroxenes. Whether, the presence of relations depicting
partially melting of original mantle, between major elements of the peridodite
xenoliths is a fact, the melting point is probably not high. They were
uneffected by metasomatism and submit a somewhat consumpted composition
compared to primitive mantle.
