Abstract

In this study, status of the weathering of rocks outcroped in the various carbonate facies at Araklı-Taşönü (Trabzon) limestone quarry were evaluated. The study area were divided into four zones, namely Zone 1 (Z-l), Zone 2 (Z-2), Zone 3 (Z-3) and Zone 4 (Z-4). Schmidt rebound hammer, ultrasonic pulse velocity and water absorption percent by weight of the rock samples were determined for each zone. A weathering classification according to the water absorption percent by weight thought to directly reflect the status of the weathering of bi-omicritic limestones was suggested based on the classifications of Schmidt rebound hammer and ultrasonic pulse velocity. According to the suggested classification, the areas have the following classes: Z-2 unweathered, Z-l and Z-4 slightly weathered and Z-3 moderately weathered. The suggested weathering classification for biomicritic limestone based on the water absorption by weight was considered to provide inexpensive, simple and practical solution for the rocks having similar properties.

Özet

Bu çalışmada, Araklı-Taşönü (Trabzon) kalker ocağında değişik karbonat fasiyeslerinde yüzeylenen kayaçla-rın ayrışma durumları değerlendirilmiştir. Çalışma sahası Zon 1 (Z-l), Zon 2 (Z-2), Zon 3 (Z-3) ve Zon 4 (Z-4) olmak üzere dört zona ayrılmıştır. Her bir zon için kayaç örneklerinin Schmidt çekici sertlikleri, ultrasonik dalga hızları ve ağırlıkça su emme yüzdeleri belirlenmiştir. Schmidt çekici sertlik ve ultrasonik dalga hızı sınıflamaları göz önüne alınarak, çalışma sahasındaki biyomikritik kireçtaşlarının ayrışma durumunu doğrudan yansıtacağı düşünülen ağırlıkça su emme yüzdelerine göre bir ayrışma sınıflaması önerilmiştir. Önerilen sınıflamaya göre; Z-2 ayrışmamış, Z-l ve Z-4 az ayrışmış, Z-3 ise orta ayrışmış sınıfına dahil olmuştur. Ağırlıkça su emme yüzdesine göre biyomikritik kireçtaşları için önerilen ayrışma sınıflamasının, benzer nitelikteki kayaçlar için ucuz, kolay ve pratik bir çözüm sunacağı düşünülmektedir.
