“…This researcher suggested that the volcanism in the region started in the alkaline character and then ended with Süphan volcanites, which showed calc-alkaline character. Açlan and Turgut (2017) stated that plutonic and volcanic units are observed around Şekerbulak (Ağrı). They said that the plutonic units were represented by Taşlıçay Granitoid consisting of tonalite, granodiorite, monzogranite and granite.…”

The study is located in vicinity of Taşbasamak, Tazekent, Davut, Boyalan, Kuşburnu and Ulukent villages in the south of Diyadin district of Ağrı city. In the study area, Paleozoic aged Batıbeyli metamorphites which consist of crystallized limestones which contain calc-schist interlevels are observed at the bottom. The Upper Miocene aged Alibonca formation composed of conglomerate, trachyandesitic tuff-agglomerate, sandy limestone, marl, dolomite-dolomitic limestone and lacustrine limestone are located unconformably on these metamorphites. Upper Miocene aged Sekirdağ volcanites consisting of daciticrhyodacitic tuffs, agglomerates and lavas are observed by lateralvertical transition over the Alibonca formation. Higher up, Lower Pliocene aged Solhan volcanites are composed of alkaline basaltic lavas are observed. The Solhan volcanites are covered by Upper Pliocene aged Hamur volcanites consisting of trachyandesitic lava and ignimbrite. Higher up, Upper Pliocene-Pleistocene aged Kale pyroclastics consisting of lapilli tuff, ash, volcanic bomb, slag and agglomerate with alkaline basalt composition are observed. These pyrolastics are covered by Upper Pliocene-Pleistocene aged Tutak volcanites which are composed of alkaline basalts. At the top, travertine and alluvium are found. Calcite + dolomite ± quartz ± muscovite mineral paragenesis is observed in metacarbonates belonging to Batıbeyli metamorphites. The tuffs belonging to the Kuşburnu pyroclastic member include quartz, plagioclase, sanidine, clinopyroxene (diopside/augite), biotite, amphibole (hornblende), sphene, opaque mineral, volcanic glass and litic fragment. These tuffs were named as lapillistone and ash tuff "according to grain size", trachyandesite tuff "according to composition and grain size", lapillistone, ash tuff and lapilli tuff "accoding to percentage distribution of grains" and vitric tuff "according to glass-crystals-lithic fragments composition". The tuffs of Sekirdağ volcanites contain quartz, plagioclase, sanidine, biotite, amphibole (hornblende), opaque mineral, volcanic glass and litic fragment. The dacitic and rhyodacitic lavas belonging to these volcantecs include quartz, plagioclase, sanidine, biotite, amphibole (hornblende), opaque mineral, plagioclase microlites and volcanic glass. Tuffs belonging to Sekirdağ volcanites were named as lapillistone and ash tuff "according to grain size", rhyodacitic tuff and dacitic tuff "according to composition and grain size", lapillistone and ash tuff "according to percentage distribution of grains" and vitric tuff "according to glass-crystals-lithic fragments". Alkaline basalts of Solhan volcanites include quartz, olivine, clinopyroxene (diopside/augite), apatite, opaque mineral and plagioclase microlites. Plagioclase, sanidine, amphibole (hornblende), clinopyroxene (diopside/augite), apatite, opaque mineral, plagioclase and sanidine microlites are observed in trachyandesites belonging to Tazekent trachyandesite member. Plagioclase, hornblende, clinopyroxene, sanidine, pumice fragments, litic fragments...

ÖZ Bu çalışma, Demirkapı (Hamur-Ağrı) dolaylarındaki volkanik kayaçların petrografik ve jeokimyasal özelliklerini ortaya çıkarmak amacıyla yapılmıştır. Çalışma alanındaki volkanitler subalkali, kalkalkali, yüksek K'lu seri ve şoşonitik özelliklere sahip olup andezit, dasit, ignimbrit ve tüflerden meydana gelirler. Bu volkanik kayaçlar hafif nadir toprak elementleri (HNTE) ve büyük iyonlu litofil elementler (BİLE) (Cs, Rb, Ba, K) açısından zenginleşme gösterirler. Karlıca volkanitlerinin Nb/Yb and (Th/Nb) N oranları sırasıyla 8.56-15.52 ve 12.59-15.43 arasında değişir. Ortalama Sr ve Ba değerleri 505.15ppm ve 626.16 ppm olup bu değerler ortalama kıtasal kabuk değerlerinin üzerindedir. Karlıca volkanitlerindeki bu zenginleşmeler ve yüksek Sr ve Ba değerlerinden bu kayaçların oluşumu ve evrimi sırasında fraksiyonel kristallenme ile birlikte kabuksal kirlenmenin de etkili bir süreç olduğu sonucu çıkarılabilir. ABSTRACT This study was carried out to reveal the petrographic and geochemical features of the rocks around Demirkapı (Hamur-Ağrı). The volcanites in the study area have subalkaline, calc-alkaline, high-K calc-alkaline and shoshonitic features and consist of andesite, dacite, ignimbrite and tuffs. These volcanic rocks show enrichments in https://doi.org/10.17824/yerbilimleri.509982 __________________________________ Mustafa AÇLAN maclan@yyu.edu.tr Açlan ve Davran / Yerbilimleri, 2019, 40 (1), 72-91, DOI:10.17824/yerbilimleri.509982 73light rare earth elements (LREE) and large ion lithophile elements (LILE) (Cs, Rb, Ba, K). The Nb/Yb and (Th/Nb) N ratios of the Karlıca volcanites range between 8. respectively. Average Sr and Ba values are 505.15ppm and 626.16ppm, respectively, and these values are higher than average Sr and Ba values of the continental crust. These enrichments in Karlıca volcanites, and high Sr and Ba values suggest that crustal contamination is an effective process with fractional crystallization during the formation and evolution of the these rocks.

The study area is Diyadin, which is situated 71 km ESE of Ağrı very close to the Turkish-Iranian State border. It is one of several type localities of promising geothermal fields in the Eastern Anatolia. The neotectonic regime and related structures are dominated by a strike-slip tectonic regime governed by a stress field in the Eastern Anatolia where the greatest principal stress (σ1) is operating in NNW direction (N22°W) while the least principal stress (σ3) is N68°E. This stress field state was proved once more by the tensor solution of the 12 June 2022 Akçift (Muradiye-Van) earthquake of Mw = 5.1. The strike-slip neotectonic regime started at the time of latest Pliocene-early Quaternary and then triggered the first occurrence of the fissure eruption along the NNW trending Kaletepe open fracture. This event was followed by the development of both the two-peaked Tendürek strato-shild volcano and the Diyadin geothermal field (DGF). The geothermal potential of the DGF is high and its most common manifestations are the active tectonic regime and related faults (extensional horse tail strucure), active volcanoes (Tendürek and Ağrı volcanoes), fumeroles, numerous hot water springs to artesian wells, widespread iron-rich alteration zones, actively growing fissure-ridge travertines and the probable presence of the unroofed hypabyssal felsic to intermediate intrusions of Quaternary age at the roots and their near environs of the isolated Quaternary volcanoes in the Eastern Anatolia. In addition, some significant similarities and contrasts are seen between the DGF and the IGF when they are compared.
