The yellow color on that siliceous mudstone looks phenomenal. I always enjoy finding yellow/brown specimens when rockhounding. Another feature that I enjoy about the siliceous mudstone is that it has a smooth and silky surface. Natures polish is always the best! Also, I have a question about the siliceous mudstone, how fragile is it? Does it easily break if not handled carefully? 0:26

美味しそうなレモンケーキの珪質泥岩ですね。他の色の石と合わせて、アフタヌーンティーの石セットが出来そうです^^
