Six-year Record of Rate of Limestone Dissolution at Three Sites in Gunung Rapat, Kinta Valley, Perak, Malaysia

Abstr ac t: Dissolution rate of limestone in the Kinta Valley is continuos ly measured. The last measurement before this study is done was taken in 200 1. The whole six yea rs has shown that limestone is further being degraded under natural environment. The esti mated dissolution on th e lim esto ne bedrock is from 0.086 to 0.1 S8 mlnlyr. However it is too early for the author to conclud e that extrapo lat ion of short term micro ero sion meter data is acceptable in this enviro nm ent. Abstr a k: Kadar pelarutan batu kapur di Lembah Kinta diukur secara berterusan . Ukuran yang terakhir sebelum kaj ian in i dibuat pad a 200 I. Masa 6 ta hun ini menunjukkan ya ng batu kapur terus mengalami pelarutan di dalam keadaan semu lajad i. Pelarutan dianggarkan dari 0.086 ke 0.1 S8 mm/tahun. Walaub aga imanapun , masih terlalu awal bagi penul is untllk membuat kes impulan ya ng datajangka masa pendek ya ng dip ero lehi dari meter erosi mikro boleh diramalkan un tuk masa aka n datang.
