Abstract

Electromagnetic VLF method can be used for the investigation of karstic cavities, which may often be seen along Turkey's southern coasts, the determination of these cavities which are naturally or artificaly: filled or halfly-filled by sea water, natural or artificial. This method is easier and more rapid than some other geophysical exploration methods. In this study, EM-VLF investigation method, which operates between 16 and 25 KHz as considered to be very low frequencies of electromagnetic spectrum, is used along with natural potential and direct current electric resistivity. During the studies, karstic cavities and fault systems related to these cavities and sea water were considered to be the most suitable model representing the region. In this model, structure is considered to be an excessively resistant medium and the fluid that fills the structure is considered to be a conductive medium.

Özet

Özellikle Akdeniz kıyılarımızda sıkça görülen, karstik boşlukların EM-VLF jeofizik yöntemi ile aranması, deniz suyu ile tam veya yarı dolmuş, doğal ya da yapay boşlukların belirlenmesi bazı jeofizik arama yöntemlerine göre hızlı ve daha kolay yapılabilmektedir. Bu makalede bu amaçla elektromanyetik spektrumun çok alçak frekansları olarak kabul edilen 16-25 KHz arasında çalışan elektromanyetik VLF arama yöntemi ile doğal potansiyel ve doğru akım elektrik özdirenç yöntemleri kullanılmıştır. Çalışmada bölgeye en uygun yapı modeli olarak, karstik boşluklar ve bunların tuzlu deniz ile ilişkilendiren bir kırık sistemi öngörülmüştür. Bu modelde yapı yüksek dirençli bir ortamdan oluşurken, bu yapının içi iletken bir akışkan ile doldurulmaktadır.
