This paper presents the results of experimental time-domain induced polarization (I.P.) soundings
carried out on drilling sights in the Muğla-Tınas lignite field. The applicability of I.P. method was investigated by
using Schlumberger vertical electrical sounding technique on Neogen sediments in a narrow graben region to obtain
thickness and depths of the formations which have different electrical properties. In order to interpret the I.P. soundings
quantitatively the chargeability values were obtained using fictitious resistivity curves and the resistivity field curves
together. The quantitative interpretation of the soundings generally corresponded very well with data from holes which
were drilled prior or after I.P. soundings in the area under investigation and it has been concluded that seperation of
the lignite series from surrounding formations was possible by their small chargeability values and that the use of this
method for lignite investigation could be useful.

Bu çalışma Muğla-Tmas linyit sahasında, yapılmış ya da yapılması planlanmış mekanik sondaj noktaları üzerinde
yapılan deneysel nitelikteki zaman ortamı indüklem polarizasyon (I.P.) sondaj sonuçlarım kapsamaktadır. Dar bir graben
sahasındaki Neojen çökelleri üzerinde, Schlumberger elektrot dizilimi ile yapılan I.P. sondajlarıyle bu ortamda yer alan
farklı elektrik özelliklere sahip formasyonların derinlik ve kalınlıklarının saptanmasında I.P. yönteminin uygulanabilirliği
araştırılmıştır. I.P. sondajlarının nicelik yönünden değerlendirilmelerinde, hayalî özdirenç eğrisi ve beraberindeki özdirenç
saha eğrisi birlikte ele alınarak yüklenebilirlik değerleri elde edilmiştir. Bu değerlendirmelerin sonuçlarıyle araştırma
sahasında yapılan mekanik sondajlardan elde edilen bilgiler çok iyi bir uyum göstermiş, genellikle, linyitli serinin küçük
yüklenebilirlik değerleriyle çevresindeki formasyonlardan ayırt edilebildiği ve yöntemin linyit aramalarında kullanılmasının
yararlı olacağı sonucuna varılmıştır.
