The local climate; which, due to its short wet season and extended dry season, experiences a lower degree of leaching that prevents rapid soil genesis, causes an increase in Si concentrations in the soil solution, and favors neogenesis of crystalline clays such as kaolinite and illite, thereby consuming a large amount of Al and Si derived from the parent material as opposed to poorly crystalline colloidal constituents such as allophone.

Abstract

This study the mineralogical characteristics of the soils from Mt. Karadağ, whose climate is semi-arid were investigated. For this purpose, samples were taken from the horizons after their macromorphological identifications were completed in all profiles and analysis for mineralogical properties was carried out. these soils lacked non-crystalline minerals like allophane, imogolite, and iron humus complexes. The only noncrystalline minerals that are present are, in great quantities, Al-humus complexes and, in small quantities, ferrihydrite. Crystallized Fe minerals were higher than the other Fe minerals. Feldspar and quartz were more common primer minerals. Hematite was also found in the profiles. X-ray diffraction indicates kaolinite and illite were dominant minerals in clay fractions. Furthermore, a considerable amount of chlorite-smectite interstrafied mineral was found to occur in the clay fraction. The local climate; which, due to its short wet season and extended dry season, experiences a lower degree of leaching that prevents rapid soil genesis, causes an increase in Si concentrations in the soil solution, and favors neogenesis of crystalline clays such as kaolinite and illite, thereby consuming a large amount of Al and Si derived from the parent material as opposed to poorly crystalline colloidal constituents such as allophone.

Özet

Bu çalışmada yarı kurak iklim şartlarında Karadağ üzerinde oluşan toprakların mineralojik özelliklerinin incelenmiştir. Bu amaçla açılan horizonlarda morfolojik tanımlamalar yapıldıktan sonra horizon esasına göre örnekler alınarak mineralojik analizler ile mineralojik analizleri desteklemek için bazı kimyasal analizler yapılmıştır. Çalışma alanındaki topraklarda allofan, imogolit ve Fe humus kompleksleri gibi amorf mineraller saptanmamıştır. Amorf formda Al humus kompleksleri ve az miktarda da ferrihidrite bulunmuştur. Kristalize demir mineralleri diğer minerallerden daha bol, en yaygın primer mineraller olarak ise feldispat ve kuvars tespit edilmiştir. Aynca profillerde hematit de saptanmıştır. X ışınları difraktogramlarma göre kaolinit ve illit kil fraksiyonunda dominant mineraller olarak bulunmuştur. Ayrıca önemli miktarda klorit smektit ara tabakalı kil mineralleri de saptanmıştır. Kısa yağışlı dönem uzun kuru sezon ile karakter ize edilen yerel iklimsel koşullar, düşiikyıkanmaya neden olarak toprak oluşumunun yavaşlamasına neden olmuş, bu da toprak solüsyonunda Si konsantrasyonunu artırarak kaolinit ve illit gibi kristalize kil minerallerinin oluşumuna sebep olmuştur. Dolayısıyla ana materyal kaynaklı yüksek Si ve Al konsantrasyonu topraklarda allofan gibi zayıf kristalize olmuş minerallerin oluşumu engellenmiştir.
