Soil gas radon concentrations have been studied in an active fault zone of Ilgın, Konya, Turkey. At this seismically active fault zone 20 km long, 3-5 km width in the study area there are two faults and a graben in between them. The maximum radon and thoron concentrations are 32601 Bq/m3 and 17628 Bq/m3 , while the minimum values are 170 Bq/m3 and 103 Bq/m3 respectively. At 15 sampling points for radon the obtained values are higher than the average values. There has been a clear visibility of both 222Rn radon and 220Rn thoron anomalies in the area. The 222Rn and 220Rn have no positive or negative correlation at sampling points in the field.

F or the last fifteen years, there has been extensive motorway and railway constructions in Turkey. This requires enormous amount of road-fillers and aggregates, and the construction companies open many open-pit limestone quarries to fulfill their aggregate needs. The partly double four lines , partly one-way double line motorway of KonyaHüyük have recently been enlarged and partly re-constructed. During this construction, a total of five limestone quarry were opened to produce limestone aggregate. The Bozlutepe Limestone member of Asmalıtepe Formation near the town of Selki HüyükKonya, central Anatolia were used for this demand, and it has been operated for the last 6 years. The limestone member is approximately 200 m thick at most and mostly made of three type of minerals and these are dolomitic limestone, crystalline limestone and quartz-bearing crystallized limestones. All the minerals are crystallized and the minerals locally dominate at the quarry. The produced aggregates have relatively flat granulometry curve indicating most of the grains are of thin and have clay-silt sized particles. Our studies revealed that Bozlutepe Limestones are formed in carbonate facies in shallow marine environments during Permian-Carboniferous times. The member most likely have low-grade metamorphism during Paleozoic and Mesozoic eras
