Turkish Journal of Earth Sciences
In the Tavşanlı Zone, the Eocene magmatism led to NW-SE trending plutons located just south of the İzmir-Ankara-Erzincan Suture Zone in Turkey. The Middle Eocene-aged Günyüzü Intrusive Complex (Karacaören, Tekören, Dinek, Kadıncık) is one of these plutonic rocks and has metaluminous to peraluminous, medium-K calc-alkaline to shoshonitic and mainly I-type granite characteristics. The plutonic rocks consist of mainly granodiorite and granite, and their mafic microgranular enclaves are widespread in these rocks. Mineral assemblages in the host rocks and enclaves also are quite similar (quartz, plagioclase, K-feldspar, biotite, and hornblende), but the latter are more enriched in mafic minerals. The enclaves …

The mafic to felsic intrusive rocks of Nay (IRN) are located in the northeast of the central Iranian block. In this study, we present new major and trace element geochemistry, U-Pb zircon ages, and Sr-Nd isotopic data to discuss the origin of the IRN postcollisional units. The oldest units in the Nay area belong to Paleocene?early Eocene volcanic and pyroclastic series including basalt-andesite, latite, dacite, and tuff. These series are crosscut by subvolcanic and granitoid rocks with lithological composition varying from quartz gabbro to K-feldspar granite. The youngest igneous activity is represented by quartz monzodiorite dikes. Hornblende-biotite quartz monzonite from …
Harmonic Numbers Associated With Inversion Numbers In Terms Of Determinants, Takao Komatsu, Amalia Pizarro-Madariaga
Harmonic Numbers Associated With Inversion Numbers In Terms Of Determinants, Takao Komatsu, Amalia Pizarro-Madariaga
Turkish Journal of Mathematics
It has been known that some numbers, including Bernoulli, Cauchy, and Euler numbers, have such corresponding numbers in terms of determinants of Hessenberg matrices. There exist inversion relations between the original numbers and the corresponding numbers. In this paper, we introduce the numbers related to harmonic numbers in determinants. We also give several of their arithmetical and/or combinatorial properties and applications. These concepts can be generalized in the case of hyperharmonic numbers.

Turkish Journal of Earth Sciences
Migmatitic rocks in the Hamedan area, Sanandaj-Sirjan Zone, Iran, contain symplectite that has partially replaced andalusite. In metatexite, symplectite typically consists of spinel + cordierite + Ca-rich plagioclase ± orthoamphibole, but in diatexite, symplectite consists of spinel + Ca-rich plagioclase; cordierite is typically absent from symplectite although it is present in the matrix of the rock. A calculated P-T pseudosection for an average, nonmigmatitic bulk-rock composition indicates that the whole-rock composition was not the effective bulk composition during the formation of symplectite. Therefore, effective bulk compositions (EBCs) were calculated using modal abundance and the average composition of minerals in contact …
