Abstract

In this study, petrographical and palynological analyses of coal samples from two regions (the Kırka region in the south, and the Karacaören region in the north) of the Sinanpaşa (Afyon) Neogene basin were performed. The coal-bearing Neogene sediments indicate the occurrence of fi ve facies: paleosol, matrix-supported conglomerate, coal-bearing mudstone, sandstone-claystone and laminated mudstones. Coal layers are mainly within coal-bearing mudstone facies. In addition, there are various types of coalifi ed materials in matrix-supported conglomerate and sandstoneclaystone facies. Based on coal petrography, an interpretation of the coal-forming environment was made. The investigated coals mainly contain a huminite maceral group. From the refl ection values (Rmax), these coals can be classifi ed as sub-bituminous in rank, and as being deposited in swamp zones associated with limnic environments. The palynological data indicates that all studied coalbearing units are of Mid-Miocene age. On the other hand, based on MAT, CMT, WMT and MAP parameters, it can be stated that at that time climatic conditions changed seasonally in the study area. Humid climatic conditions prevailed during the period when the peat was formed, then later transformed into the coal layers examined in this manuscript.

Özet

Bu çalışmada Sinanpaşa (Afyon) Neojen havzası içerisinde iki bölgede (güneyde Kırka bölgesi,kuzeyde Karacaören bölgesi) yer alan kömür örneklerinin petrografi k ve palinolojik incelemeleriyapılmıştır. Kömür içeren Neojen tortulları beş fasiyese ayrılarak incelenmiştir. Bunlar alttanüste doğru; paleosol, bağlayıcı destekli çakıltaşı, kömürlü çamurtaşı, kumtaşı-kiltaşı ve laminalıçamurtaşı fasiyesleridir. Kömürlü seviyeler belirgin olarak kömürlü çamurtaşı fasiyesi içerisindeyer almaktadır. Ayrıca bağlayıcı destekli çakıltaşı ile kumtaşı-kiltaşı fasiyeslerinde de çeşitliboydaki kömürleşmiş malzemeye rastlanmaktadır. İnceleme alanından derlenen örneklerin kömürpetrografi si incelemeleri yapılmış ve bunlara bağlı olarak kömürlerin çökelme ortamları ile ilişkiliyorumlamaya gidilmiştir. Buna göre bu kömürlerin başlıca gelinitçe zengin olan hüminit maseralgrubunu içerdiği, Rmax değerlerine göre alt bitumlu kömür sınıfl amasına girdiği ve göllerleilişkili bataklık zonlarında çökeldiği sonucu ortaya çıkmaktadır. Örneklerin derlendiği düzeye aitpalinolojik veriler kömürlü birimlerin yaşının Orta Miyosen olduğunu işaret etmektedir. Paleoiklimçalışmaları sonucunda elde edilen MAT, CMT, WMT ve MAP parametrelerine dayanarak çalışmaalanındaki iklimsel koşulların mevsimselliğe bağlı olarak değiştiği gözlenmiştir. Sonuç olarak,kömürlü seviyelerin oluştuğu dönemde ılıman iklim koşullarının varlığından söz edilebilir.
