Geochemical properties of soils surrounding the Deliklitaş Au deposit, Turkey
(Pergamon-Elsevier Science Ltd, 2016)The Deliklitas gold deposit is in northwest Turkey, where a renowned gold province containing many major hydrothermal deposits related to Tertiary volcanic rocks. Because of the limited outcrops in the region, one of the ... -
Macromolecular composition of terrestrial and marine organic matter in sediments across the East Siberian Arctic Shelf
(Copernicus Gesellschaft MBH, 2016)Mobilisation of terrestrial organic carbon (terrOC) from permafrost environments in eastern Siberia has the potential to deliver significant amounts of carbon to the Arctic Ocean, via both fluvial and coastal erosion. ... -
Source, transport and fate of soil organic matter inferred from microbial biomarker lipids on the East Siberian Arctic Shelf
(Copernicus Gesellschaft MBH, 2016)The Siberian Arctic contains a globally significant pool of organic carbon (OC) vulnerable to enhanced warming and subsequent release by both fluvial and coastal erosion processes. However, the rate of release, its behaviour ... -
Petrology of Eocene volcanic rocks from the Central Sakarya Zone (northwestern Anatolia, Turkey): new evidence from Ar-Ar and Sr-Nd isotope determinations
(Springer Verlag, 2016)In this study, petrological characteristics of the Early-Middle Eocene Bozanic volcanic rocks resulting from the closure of the Neotethys Ocean in the Central Sakarya region and geodynamic evolution of the Eocene magmatism ... -
Coal characteristics, elemental composition and modes of occurrence of some elements in the isaalan coal (Balikesir, NW Turkey)
(Elsevier Science Bv, 2017)"This study uses coal petrography, micro-FTIR, mineralogical, and geochemical analyses to determine the coal characteristics and controlling factors of elemental enrichments in the Isaalan coal (NW Turkey). The obtained ... -
Performance and sustainability of district-scale ground coupled heat pump systems
(Springer, 2017)This study proposes a solution to the problem of maintaining the performance and sustainability of district-scale, cooling-dominated ground coupled heat pump (GCHP) systems. These systems tend to overheat because heat ... -
SHRIMP U-Pb zircon ages and whole-rock geochemistry for the Sapc volcanic rocks, Biga Peninsula, Northwest Turkey: implications for pre-eruption crystallization conditions and source characteristics
(Taylor & Francis Ltd, 2017)Palaeogene and Neogene volcanic rocks are widespread on the Biga Peninsula of Northwest Turkey. These rocks were formed during the Eocene, Oligocene-Miocene, and late Miocene, and the early Miocene Sapc volcanic rocks in ... -
Preliminary results of the radiolarian-chert hosted manganese deposit within the Vezirler ophiolitic melange (Kula-Manisa, western Turkey): constraints on the origin, paleo-redox conditions, and depositional environments
(Springer Heidelberg, 2018)In Turkey, Late Cretaceous ophiolitic complexes and melange assemblages of the Izmir-Ankara-Erzincan Suture Zone, part of the northern branch of the Neotethys Ocean are rich in Mn-oxide deposits. These deposits are related ... -
Soft-sediment deformation structures related to tectonomagmatic activity: A case study from the borate-bearing lacustrine deposits of early Miocene Bigadic Basin, NW Turkey
