Pak PTA Yth.,
Kalau batuan sedimen non marinnya ada sisian batuan produk volkanik primer
seperti tufa dan/atau batu apung primer, barangkali bisa digunakan metoda
radiometri dengan Potasium-Argon (K/Ar) atau Argon-Argon (Ar/Ar) terhadap
mineral biotit,piroksen atau hornblenda yang terkandung dalam tufa dan/atau
batu apung primer tersebut.
