Alkali-feldspar in an alkaline rock shows evidence for the formation of iron rich primitive clay precursors in the earliest weathering stage. High-resolution TEM with EDAX, electron diffraction patterns and lattice images clearly show the decomposion of Alkali-feldspar and growth of primitive sheet structure mineral. The primitive clay precursors consist of Si and Fe with small amount of K and Al. These precursors with 14-20 A spacing show diffuse rings electron diffraction pattern due to low crystallinity and random orientation. The diameter of precursors is 150-200 A.
