TI  - CONTACT METAMORPHISM OF LATE SILURIAN-EARLY CARBONIFEROUS METACARBONATES BY METAMAFIC DYKES AROUND LADIK AND ESIRAĞIL AREA (KONYA, CENTRAL TURKEY)
AB  - In NNW Konya, mafic rocks form as dyke swarm or isolated linear dykes, which are cut by a series of normal faults that developed possibly by emplacement of the dyke-forming magma. Some anhydrous oxidized calcic skarn zones have ever been found out in Silurian-Early Carboniferous metacarbonates next to the Triassic metamafic dykes faulted, and in roof pendants within the intrusion. The metamafic rocks are suggested to have a low temperature and a small amount (or even absence) of the heat of crystallization, which causes the development of a restricted skarn zone. Mineralogical studies show that the skarn contains garnet, magnetite/hematite, chlorite, and sericite.  The magnetite/hematite minerals form mostly as large euhedral crystals, up to 0.5 cm in length, which may be resorbed by chlorite and felsic minerals or rimmed by goethite. The garnet typically forms as spectacular euhedral large crystals, up to ~1.5 mm in size.  The existence of chlorite and sericite, and the lack of hornblende, biotite and wollastonite in the region indicate that contact metamorphism took place under low pressure, relatively low temperatures (albite-epidote hornfels) and/or high CO2 conditions in the area.
