GIANT FOSSIL WOOD Java, Indonesia H. 51 ¼ in - W. 16 ¼ in Fossilization of plants and trees is rarer than that of other organisms and presupposes the coincidence of a number of favorable factors: the covering of the area by water or volcanic ash so as to create an oxygen-free environment that prevents rapid destruction, quick deposition of sediments such as clays and sands that bury and preserve the trunks from further degradation, and the presence of circulating fluids rich in silica that allows the phenomenon of silicification of the woody material. The petrification process ensures that all features such as knots, bark and annual rings of the wood are preserved. The type of soil in which the fossil wood was preserved determines its aesthetics. Colorations result from the presence of different minerals. If the color shades tend toward a warm hue they indicate to us the presence of a clay soil, in the case of cooler hues, gravelly.
