Microthermometric Characteristics Of The Oxidized Type W-Skarn, In Susurluk, Balikesir, Turkey, Ayşe Orhan, Halim Mutlu, Nurullah Hani̇lçi̇
Microthermometric Characteristics Of The Oxidized Type W-Skarn, In Susurluk, Balikesir, Turkey, Ayşe Orhan, Halim Mutlu, Nurullah Hani̇lçi̇
Bulletin of the Mineral Research and Exploration
The Susurluk skarn deposit developed at the contacts the Çataldağ Granitoid and Mesozoic carbonate rocks is represented by endo and exoskarn (proximal zone, distal zone and vein skarn) zones. The endoskarn zone which occurs in a limited area is characterized by clinopyroxene, plagioclase, sphene, orthoclase and quartz minerals. The exoskarn zone is composed mainly of clinopyroxene, vesuvianite, wollastonite and some accessory minerals such as calcite, quartz, plagioclase, orthoclase, scapolite, biotite, muscovite, sphene and chlorite and ore minerals of scheelite, chalcopyrite and bornite. The presence of anhydrous minerals such as garnet and clinopyroxene is indicative of prograde stage, and the absence …
Investigation Of Crustal Structure Of Turkey By Means Of Gravity Data, Selim Arslan, Uğur Akin, Atakan Alaca
Investigation Of Crustal Structure Of Turkey By Means Of Gravity Data, Selim Arslan, Uğur Akin, Atakan Alaca
Bulletin of the Mineral Research and Exploration
During this work, the regional gravity data acquired earlier were used and in order to investigate the relations between geology - tectonics and elevation, isostatic map of Turkey, free air anomaly map and Bouguer anomaly maps were obtained, and comparisons with respect to elevations were carried out. For the thickness of the earth crust T 0 32 - 0.08g relation was used. The best relation was obtained from Bouguer anomaly with +0.65 coefficient; the relation function was obtained as Y = - 72E + 7.77. Thickness of the crust of Turkey is estimated to be 31.4 km where it is …
Actual Bloedite Mineral Precipitation In A Seasonal Lake In Çankiri-Çorum Basin, İlhan Sönmez
Actual Bloedite Mineral Precipitation In A Seasonal Lake In Çankiri-Çorum Basin, İlhan Sönmez
Bulletin of the Mineral Research and Exploration
Bloedite (Na2Mg(SO4)2.4H2O) which is an economically important sodium sulfate mineral currently precipitates through evaporation in Lake İshaklı, a small seasonal lake (playa lake) situated to the north of İshaklı Village (Bayat - Çorum) in Çankırı-Çorum Basin. Lake İshaklı, in which actual bloedite precipitation has been determined for the first time by this work in Turkey, extends in East-West direction and covers an area of approximately 220 000 m2 . During winter and spring months it becomes a lake with a depth of more than 2 m. However, during hot periods when evaporation …
Investigations Of Alteration Zones Based On Fluid Inclusion Microthermometry At Sungun Porphyry Copper Deposit, Nw Iran, Omid Asghari, Ardeshir Hezarkhani
Investigations Of Alteration Zones Based On Fluid Inclusion Microthermometry At Sungun Porphyry Copper Deposit, Nw Iran, Omid Asghari, Ardeshir Hezarkhani
Bulletin of the Mineral Research and Exploration
The Sungun porphyry copper deposit is located in East Azerbaijan, NW of Iran. The porphyries occur as stocks and dikes ranging in composition from quartz monzodiorite to quartz monzonite. Four types of hypogene alteration are developed; potassic, phyllic, propylitic and argillic. Three types of fluid inclusions are typically observed at Sungun; (1) vapor-rich, (2) liquid-rich and (3) multi-phase. Halite is the principal solid phase in the latter. The primary multiphase inclusions within the quartz crystals were chosen for micro-thermometric analyses and considered to calculate the geological pressure and hydrothermal fluid density. In potassic zone, the average of homogenization temperature is …

Sediment Core Studies On The North Anatolian Fault Zone In The Eastern Sea Of Marmara: Evidence Of Sea Level Changes And Fault Activity, Erol Sari, Namık Çağatay
Bulletin of the Mineral Research and Exploration
Sediment cores BUC-10A and ÝZ-30 located on the North Anatolian Fault Zone (NAFZ), 12 km south of Büyükçekmece and Ýzmit Gulf in the eastern part of the Sea of Marmara, respectively, were studied to investigate tectonics and paleo-oceanographic processes, using sedimentological and geochemical methods. Total inorganic carbon (TIC as total calcium carbonate) and total organic carbon (TOC) contents in core BUC-10A range between 12.1-34.3 and 0.5-4.1 dry wt. %, respectively. The organic matter-rich sapropel unit was identified between 1.60 and 2.43 m below sea floor (bsf) in this core. The concentration ranges of the metals in core BUC-10A were: Cr: …

Preliminary Findings On The Fossil Traces In The Massive Sulphite Deposits Of Eastern Black Sea Region (Lahanos, Killik And Çayeli), M. Kemal Revan, Taner Ünlü, Yurdal Genç
Bulletin of the Mineral Research and Exploration
Tube worm fossils have been found in the Upper Cretaceous aged massive sulfide deposits of the Eastern Black Sea Region. Similar ones of these tube worm fossils have been found in the massive sulfide deposits of Umman, Cyprus, Ireland and Urals. This fossil community defined in very few massive sulfide deposits in the world is the important evidences of the sea floor hydrothermal vents in Pontids. These worm-like forms can be considered as the ancestral forms of the unusual vent communities defined in places where modern hydrothermal vents are observed such as East Pacific Rise, Galapagos and Juan de Fuca …

Bulletin of the Mineral Research and Exploration
Technological analyses of zeolites are important for their areas of use. Zeolite samples were collected from different regions (İzmir-Foça, Balıkesir-Bigadiç, Manisa-Gördes) for this study. First mineralogical and chemical analyses of the samples were conducted in the study. Later on, technological tests of the samples were made for their utilizing in ceramic industry (pre-technological), in paper industry (filling and coating) and as cat litter. Finally, the results were evaluated. It was concluded that some samples can be used in baked ceramics in the ceramic industry; they have high whitening properties to be used in paper industry. As for cement additives, their …
